A study was conducted to estimate the influence of gibberellic acid (GA3) at different concentrations in different time intervals on seed germination and seedling growth of kagzi lime. The results revealed that Maximum germination percentage (95%) was recorded under treatment with GA3 80 ppm for 12 hours, rate of germination of seeds (25 days), height of plant (18.79 cm) at 120 DAS, number of leaves per plant (26.53), fresh and dry weight of shoot (25.84 g and 14.44 g), tap root (17.44 cm), secondary and fibrous roots (5.98 and 85.99), fresh as well as dry weight (7.04 and 4.95 g), survival percentage (85 percent) in similar treatment. Therefore, it may be concluded that the GA3 at 80 ppm has a significant effect on the seed germination and seedling growth of Kagzi Lime and can be recommended to the grower for obtaining better growth and yield.

An experiment was conducted with a local cultivar of garlic to study the effects of planting date and gibberellic acid on the growth and yield of garlic at the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during November 2001 to April 2002. Early planting influenced the plant height, leaf number, bulb diameter and total dry matter. With the delay in planting time starting from November 7, the yield was chronologically reduced in later plantings. Significantly the highest bulb yield (2.67 t/ha) was recorded when planting was done on November 7 and lowest yield (0.92 t/ha) was obtained from December 22 planted crop. Bulb yield was higher in control plants than those of GA3 treated plants. The interaction effects of planting date and different concentrations of GA3 differed significantly in respect of plant height, number of leaves, bulb diameter and dry weight of roots, leaves and bulbs and yield of garlic.

Aims: This study aimed to optimize the levels of gibberellic acid (GA3) and plant spacing on growth and yield of lettuce. Study Design: The experiment was laid out in Randomized Complete Block Design with three replications. Place and Duration of Study: Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka-1207, from November 2013 to January 2014. Methodology: The experiment consisted of two factors. Factor A- two levels of gibberellic acid (GA3,) application, viz. G1= 25 ppm and G2= 50 ppm in relation to a control G0 and factor B- four plant spacing viz. S1=15cm x 15cm, S2=20 cm x 20 cm, S3=25 cm x 25 cm and S4=30 cm x 30 cm. GA3 was applied twice as a foliar application by hand sprayer at 20 and 30 days after sowing. First, second and final harvesting was done at 25, 35 and 45 days after sowing respectively. Results: The growth and yield characters of lettuce showed significant variation for different levels of GA3 and plant spacing. Among GA3 levels, 25 ppm GA3 produced the maximum number of leaves (15.6), leaf area (283.9 cm2), fresh weight (91.6 g plant-1), dry weight (11.8 g plant-1), fresh yield (1794 g plot-1) and gross yield (12 t ha-1) at final harvesting compared to control where GA3 was not used. Under plant spacing, highest plant height (17.5 cm), leaf area (281.1 cm2), fresh weight (99.1 g plant-1) and dry weight (12.1 g plant-1) was revealed from wider spacing 30 cm x 30 cm followed by optimum spacing 25cm x 25cm. Meanwhile, closure spacing 15 cm x 15 cm showed maximum fresh yield (1710 g plant-1) and gross yield (15.5 t ha-1) due to higher plant density at final harvesting. Besides, lower chlorophyll content (0.43%) and the highest number of leaves (16.2) was found from 25 cm x 25 cm at final harvesting. So, optimum spacing 25 cm x 25 cm would be more suitable considering different points of view. Moreover, the treatment combinations 25 ppm GA3 with 25 cm x 25 cm exhibited highest benefit-cost ratio (2.04) than other treatments. Conclusions: It is concluded that the combinations 25 ppm GA3 application with 25cm x 25cm spacing would be optimum for better growth and yield of lettuce

Aims: To investigate the effect of storage treatments, gibberellic acid (GA3) and duration of soaking on seed germination and seedling growth in Kagzi lime. Study Design: The experiment was laid out in a Completely Randomized Design (CRD) with factorial concept and three repetitions. Place and Duration of Study: The experiment was conducted during July to November 2017 at Department of Fruit Science, Navsari Agricultural University, Navsari, Gujarat, India. Methodology: The experiment consisted of sixteen treatments which were repeated thrice. It comprised of three factors and their respective levels. Factor S1 indicated freshly extracted kagzi lime seeds and S2 comprised of seeds stored for 15 days. The different concentrations of gibberellic acid were G1 - 200 ppm; G2 - 300 ppm; G3 - 400 ppm and G4 - 500 ppm. Whereas, duration D1 stood for 12 hours and D2 for 24 hours. Results: The interaction between storage treatments, pre-sowing treatments and duration of soaking was found significant for all parameters included in the study except collar diameter and sturdiness quotient. Soaking freshly extracted Kagzi lime seeds in an aqueous solution of 500 ppm GA3 for 12 hours resulted in the minimum days for 50% germination (27.89), Seedling Vigour Index (3654.83) and survival percentage (84.70). The same treatment when extended for 24 hours recorded the highest germination percentage (95.68) and number of leaves (28.76). Soaking freshly extracted seeds in 400 ppm GA3 solution for 12 hours registered the maximum shoot length (21.63 cm). Kagzi lime seedlings raised from freshly extracted seeds resulted in higher collar diameter (2.04 mm) and sturdiness quotient (8.70). Further, a soaking duration of 12 hours proved better over 24 hours for collar diameter (2.04 mm) and sturdiness quotient (8.69). Between the different concentrations of GA3, 400 ppm gave better results for collar diameter (2.09 mm) and 200 ppm for sturdiness quotient (8.65).   Conclusion: Soaking freshly extracted kagzi lime seeds in an aqueous solution of 500 ppm GA3 for 12 hrs proved to be the best treatment combination for inducing early germination, higher Seedling Vigour Index and survival percentage. Nurserymen can employ these findings for early germination and vigorous seedlings in Kagzi lime.

Three experiments were conducted in a plastic greenhouse at the Sinna Garden of the Crop Science Department of the University of Ghana, Legon, Accra to investigate into pre-sowing treatment (water treatment, growth regulator, and sulphuric acid scarification and water soaking) effects on seed germination and seedling growth of Bauhinia rufescens from October to December, 2011 and January to April, 2012, respectively. The experimental design used was complete randomized design. There were 4 treatments in experiment 1, 7 in experiment 2 and 6 in experiment 3. Each experiment was replicated five (5) times. The results showed that Bauhinia rufescens seeds soaked in hot water at 65 0 C for 60 minutes gave the highest mean germination rate, tallest plant height and highest number of leaves per plant at 49 days after soaking. It also had the widest stem diameter, highest fresh shoot and root weight, highest fresh root and dry root weight and number of roots per seedling. Seeds soaked in 500 ppm Gibberelic acid(GA3) produced the highest number of leaves per plant and tallest plants at 49 DAS. Seeds soaked in 750 ppm GA3 had the highest number of leaves per plant at 49 DAS and highest fresh shoot weight. Seeds soaked in 1000 ppm Promalin differed significantly from 500 ppm GA3 and the control in germination percentage. Seeds soaked in 1000 ppm Promalin differed significantly from 500 ppm GA3 and the control in germination percentage. Acid scarified seeds for 60 minutes plus soaking in tap water for 24 hours differed significantly from the seeds treated withother growth regulator rates plus 24 hours soaking in germination percentage. Acid scarified seeds for 45 minutes plus soaking in tap water for 24 hours had the tallest plant and highest number of leaves per plant at 49 DAS, widest stem diameter, highest fresh shoot and root weight and dry shoot weight. Soaking seeds in hot water at 65 0 C for 60 minutes and/or in acid (H2SO4) for 45 minutes plus soaking in tap water for 24 hours is recommended as pre-sowing treatment for Bauhinia rufescens for maximum mean germination rate and vigorous vegetative growth of seedlings.

Saline soils contain multiple types of salt, each of them may exert a different effect on seed germination and seedling growth. The aim of this study is to assess the effects of five types of salt on the seed germination and radicle establishment of common bean (Phaseolus vulgaris L. var. Djedida). The experiment was set out as a factorial experiment based on completely randomized design with four replications of ten seeds for the seed germination and twelve replicates for the seedling growth. We used five kinds of salts (NaCl, Na2SO4, CaCl2, CaCO3 and KCl) with concentrations of 0, 100, 200 and 300 mM. Seeds were incubated in Petri dishes at 25°C, in the dark, for 10 days. The results of analysis of variance indicated that the effects of salt types and concentrations, and their interaction effect were significant in all measured traits (P< 0.01). However, no significance effect was found on secondary roots number and seedlings dry biomass with CaCO3 treatment solution. According to the results, the inhibitory effects of the five salt types differed significantly. Indeed, germination of common bean seeds by various salts were in the order of NaCl > KCl > CaCO3 > Na2SO4 > CaCl2. However, the taproot length, the number of secondary roots and the seedlings dry weight by various salts were in the order of CaCO3 > KCl > NaCl > CaCl2 > Na2SO4. The effect of salt concentration was also obvious. The reduction in dry biomass of cotyledons is proportional to germination rates and to the development of seedlings in dry biomass and in size. Seeds of P. vulgaris var. Djedida were able to germinate under all concentrations of the various types of salt. The lowest final germination percentage (FGP) was obtained under 300 mM of all salts recording the following values: CaCO3 - 60%, NaCl - 60%, KCl - 52.5%, Na2SO4 - 50% and CaCl2 - 27.5%. During germination stage, the radicle emergence would be controlled by the environment osmolarity, while the later growth of the seedling would be limited by the reserve mobilization.

Abstract Seeding is the most important and quite challenging stage in seed/TSS cultivation. Plant growth regulator (PGR) seed priming has the potential to enhance the quality of TSS seedlings. The research had been conducted in the greenhouse of Agriculture Faculty, UGM, from February to April 2020. The factorial treatments of shallot cultivars (Tuk-Tuk, Lokananta and Sanren) and seed treatments (soaking seed with GA3 100 ppm and NAA 50 ppm for 12 hours and untreated seeds as control) were assigned in the RCBD with four replications. Each experimental unit was consisted of 728 seeds per cultivar. Both treated and untreated seeds were sown in soil blocks. The data were analyzed using ANOVA and continued with Tukey HSD procedure at α=0.05. The results showed that PGR priming on seeds significantly increased the germination percentage, plant height, leaf number, leaf area, and hypothetical vigor index of the three cultivars at six weeks after sowing. However, there was no significant difference in the fresh weight and dry weight of seedlings. This research implied that soaking seeds in GA3 100 ppm and NAA 50 ppm for 12 hours could improve seed germination and TSS seedling growth. Additional fertilizers are perhaps needed in soil blocks to increase the effect of hormones on the seedlings.

Seeds of tomato cv. Keabi were primed with of three important growth regulators viz Gibberellic acid (GA3), Napthlene acetic acid (NAA) and potassium nitrate (KNO3). Four concentration of each, Gibberellic acid and Napthlene acitic acid (25ppm, 50ppm, 75ppm.100ppm) and two concentration of KNO3 (1% and 2%) were compared with the distilled water as control. For each treatment seeds were soaked in growth regulator for 24 hrs before put for the germination test. Fifty seeds in four replications were germinated on top of paper at 200C in seed germinator for 14 days. Normally germinated seedlings were counted which gave an estimation of germination percentage. Data was recorded on the germination percentage, shoot length, seed vigour index. Most of the treatments had significant positive effect on all the quality parameters. NAA had showed adverse effect on the root length while other growth regulators were found to be significant role to improve the root length. Maximum seed germination (74%) was observed at 50 and 75ppm GA3. Highest shoot length (4.83cm) was found at 25ppm of GA3 whereas enhancement of root length occurred with the priming of 1% KNO3 (3.52cm ). Seed vigour-I, on the basis of seedling length was observed higher at 25ppm. GA3 (720) and seed vigour –II on the basis of seedling dry weight was also observed maximum priming with 100ppm GA3 (1460). From this study it was suggested that GA3 priming has important growth regulator to enhance the seed germination as well as seed vigour. Before sowing seed should be priming with GA3 for obtaining high % germination and vigorous seedling that survive under adverse condition it also increase the uniformity of field plant stand.

The effect of root exudates of fifty Sorghum genotypes on seed germination and seedling growth of millet were studied in vitro. The fifty genotypes were divided into four groups according to their effect on percentage reduction in root and shoot and whole plant average lengths of millet seedling growth. The first group caused slight stimulation, the second slight inhibition, the third gave limited inhibition and the fourth caused high inhibition. In seedling growth. Five genotypes of sorghum were selected, one from group two and four from group four. These five genotypes were cultured in the field in Autumn 2007 and at the end of the season plants were removed, dried and grind. Three concentrations of each of these genotypes powder were prepared, in addition to the control treatment, (0.0, 3.0, 6.0 and 9.0) g/kg soil to study their effects on the growth of Amaranthus retroflexus which cultured in pots and kept in experimental field. Data on number of leaves, lengths of shoot and root and whole plant were taken as well as wet and dry weight were measured. Percentage of Amaranthus retroflexus seeds germination were evaluated in an experiment cultured in Petri dishes containing concentrations (0.0, 5.0 and 10.0%) of aqueous extracts of each of the five genotypes powder. Results showed high significant inhibition for the four genotypes from group four in comparison with the one genotype from group two. Significant differences among these genotypes in their inhibition on such parameters as shoot, root, whole plant growth, number of leaves, and wet and dry weight. The genotype 2005-K-Type 1050 gave the highest reduction in plant length 53.2% incomparing with the genotype 2005-K-Type 1033 which gave 0.7%. The percentage of seed germination of Amaranthus retroflexus was significantly reduced as the concentration of the aqueous extract increased and there were significant differences among genotypes on this parameter. The concentration of the powder of each genotype added to the soil produced significant reduction in all parameters studied and the effect increased as the concentration increased in soil. This research discusses the potential of the allelopathic effect of some Sorghum genotypes on weed germination and growth reduction and the possibility of employing them in weed control program with the intention to use less herbicide.
