The present investigations “Studies on the effect of pre-sowing treatment and time of wedge grafting on production of saleable grafts in mango” were carried out in the nursery block of Fruit Science Department. The study was conducted using wild mangoes seeds. The seeds were divided in two equal halves, one half of seeds were sown with intact seed coat (K1) while, in other half the mango kernels were extracted (K2), both type of seeds were then soaked in 6 different chemicals of varying concentrations viz. C1- KNO3 @ 0.5%, C2- KNO3 @ 1%, C3- KNO3 @ 1.5%, C4- BA @ 50 ppm, C5- BA @ 100 ppm, C6- GA3 @ 100 ppm, C7- GA3 @ 200 ppm, C8- beejaaumrit @ 2%, C9- beejaaumrit @ 3%, C10- panchgavya @ 2%, C11- panchgavya @ 3% for 12 hours and C12- Control. The germination and vegetative parameters were observed. The results of study revealed that the e×tracted kernels pre-soaked with GA3 @ 100 ppm produced earliest germination, 50 % germination, high rate of germination, germination percentage, number of leaves, maximum leaf area, highest seedling vigour index, while, on pre-soaking extracted kernel with KNO3 @ 0.5% produced maximum seedling diameter. The Seedling raised from extracted kernels pre-soaked in KNO3 @ 0.5% (C1K2) attained graftable diameter within 210 days of sowing. The present investigation was conducted during 2019-2020 at the nursery block of College of Horticulture and Forestry, Neri Hamirpur (H.P) to study the effect of pre-sowing treatments on germination, growth and production of graft-able seedlings.

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.

The continuous rise in global population demands more food production under limited land resources accompanied by climate change. More oversupply of quality seeds to meet ever-growing food demand is a highly challenging task. Seeds with low vigour level limit the growth and yield of crops at varied field conditions. Hence, an experiment was conducted to develop a technique for the fast and homogeneous growth of kabuli chickpea seeds. The priming treatments evaluated in the present study enhanced the various seed quality parameters of kabuli chickpea significantly when compared to control. Hydro-priming for 4 hours (at 20°C) and air drying for 72 hours showed better results compared to rest of the treatments both in fresh seeds which recorded higher first count (66.38%), germination (92.50%) root length (11.85 cm), shoot length (6.16), mean seedling length (18.01), dry seedling weight (747 mg), seedling vigour index-I (1665), higher speed of emergence (0.3992) and old seeds with higher first count (61.88%), germination (74.13%) root length (8.15 cm), shoot length (5.85 cm), mean seedling length (14.00 cm), seedling dry weight (611 mg), seedling vigour index-I (1056), higher speed of emergence (0.3814). The aged seeds have recorded 29 % increase in germination percentage in contrast to 8 percent increases in fresh seeds. Kabuli chickpea seeds could be subjected to hydropriming, an affordable, alternative, and eco-friendly technique for improving seed and seedling vigour of kabuli chickpea.

The aim of this work was evaluate the effect of different levels of light intensity on the physiology, vegetative and reproductive development of Heliconia bihai cv. Lobster Claw Two grown under coastal zone of Ceara State. Plants of this species were grown under full and 30%, 40% and 50% reduction sunlight intensity. It was evaluated the number of leaves and tillers per plant; amount of stalks; leaf area, water and carbohydrate content in the leaf next to the inflorescence arising and next to the inflorescence at harvest stage. Photosynthesis, transpiration and stomatal conductance of plants were measured for six consecutive months. Significant difference were attained for leaf area and water content in leaves close to the inflorescence at harvest stage, with lower values, and carbohydrate contents in leaves, with higher values in plants grown in full sun. The treatments with lower levels of solar radiation had higher amounts of stalks and higher vegetative growth, the reduction in vegetative growth of the plants under full sun was due to the lower photosynthetic rate and lower translocation of assimilates.

Papaya is a very popular fruit in the tropical and subtropical regions of the world and has witnessed an increase in demand. This has fuelled an interest to develop region specific hybrids with desirable vegetative growth and vigour.  Hence a field experiment was carried out at College of horticulture and forestry, Navsari Agricultural University in Gujarat during 2018-2020 in randomized block design with three replications to know the mean performance of parents and hybrids for comparative growth performances of papaya. Wherein, thirty papaya hybrids were developed from six morphologically distinct parents through full diallel crossing technique and all the parents and hybrids were evaluated for their germination and growth parameters. The variability was distinct in all hybrids and parents for germination percentage, days taken to germination, periodical plant height and girth, number of leaves, petiole length and internodal distance. Amongst all the parents, Pusa Delicious, CO-8 and Lucknow Local exhibited improved germination, better vegetative growth and dwarf stature, respectively. Among the hybrids, Pusa Delicious x Lucknow Local was found to have dwarf stature with minimum internodal length however, the reciprocal cross: Lucknow Local x Pusa Delicious recorded maximum plant girth and number of leaves. Based on their mean performance, these parents can be used for further breeding programmes and hybrids could be exploited for cultivation.

Soapnut (Sapinduas emarginatus) is one of the most primitive precious useful plants since ancient times. This plant was domesticated due to its multifarious usefulness. The study was conducted in College of Forestry, Sirsi during 2019-20 to know the influence of post scarification storage treatments on seed germination and quality in Sapinduas emarginatus. The seeds were collected from in and around Sirsi area. In soap nut, the basic problem is poor seed germination due to hard seed coat. The seeds were treated with concentrated H2So4 for 12min and stored under laboratory condition for six months. At monthly interval, seed samples were drawn and evaluated for post scarification germination. The germination behaviour remarkably influenced due to scarification and without scarification during experimentation. The untreated seeds recorded the maximum germination (68%) compared to scarified seeds (22.85%).Speed of germination was highest in seed without scarification treatment (2.7) compared to scarified seeds. Mean daily germination was highest in without scarified seeds (1.04) and lowest in the scarified seeds (0.32). Peak value was maximum in without scarified seeds (0.50) compared to scarified seeds (0.22). Seedling vigour index was significantly highest in without scarified seeds (1290) compared to scarified seeds (455). In general, scarified seeds with conc. H2SO4 for 12 min affected seed germination due high conc. H2SO4 because of chemical residues remaining in seed that affects the embryo. As the advancement in storage period the seed coat may lose the integrity so, germination was improved in without scarified seeds.

Bottle gourd is an important cucurbitaceous crop. The impact of 14 species from eight fungal genera on bottle gourd seeds was studied through in vitro tests. Bottle gourd seeds were inoculated with each isolate separately and subjected to various germination tests. Maximum germination inhibition was upto 69.3% due to Fusarium proliferatum. Inoculation of seeds with F. proliferatum significantly reduced the germination speed index to 2.69. The seedling vigour index I for seeds inoculated with F. proliferatum and F. incarnation-equiseti (species complex) was 860 and 861, respectively, significantly different from that of non-inoculated seeds having a vigour index of 1791. The seedling vigour index II of seeds inoculated with F. proliferatum was 1818, significantly lower than the control (4631), indicating that the F. proliferatum isolate was highly virulent among all the isolates. Amongst seven plant protectants evaluated for their efficacy as seed dressers against F. proliferatum, propioconazole (25% EC), copper oxychloride (50% WP) and Mancozeb (75% WP) were effective in reducing infection. Germination percentage was highest for seeds treated with the bioagent Trichoderma harzianum 1% WP.

Background: Selenium (Se) is an essential trace element to higher plants, animals and humans, but low Se levels are a global public health concern. Seed priming has become a basic strategy for the production of Se-riched agricultural products, but its application is still not clear in the production of Se-enrich alfalfa, hence this study was conducted for the production of Se-enriched alfalfa by seed priming with different concentrations and time on seed vigour. Methods: Seeds were primed with 0, 0.5, 1.0, 2.0, 4.0 and 8.0 mmol L-1 of sodium selenite solution for 0, 3, 6, 9 and 12 h at 20°C and their germination percentage, germination index, seedling vigour index and mean germination time were analyzed. Result: Seed vigour of alfalfa was improved by priming with low selenium (Se) concentration (0.5 and 1.0 mmol L-1), but was inhibited by high Se concentration ( greater than 2.0 mmol L-1). Hence, it must be necessary to carefully select appropriate concentration and time for the application of Se priming in alfalfa seeds. The optimal manner of Se priming in alfalfa seeds might be at 1.0 mmol L-1 concentration for 9 h.

Background: Understanding the drought tolerance of white clover seeds during germination and early seedling growth and how that is linked to seed maturation in legume species, is crucial to developing new stand establishments.Methods: An experiment was conducted in Randomized Block design in two factorial concept to explore how seed maturation and drought tolerance influence seed germination and early seedling growth using the two factors: seed coat color (yellow and brown, two levels as one factor) and drought intensity (control: 0 MPa [distilled water], mild drought: -0.2 MPa, moderate drought: -0.4 MPa and severe drought: -0.6 MPa, four levels as another factor).Result: In contrast to the yellow-coated seeds, the mean germination percentage, germination index, seedling vigour index and radicle length of the brown-coated seeds were lowered by 7.9%, 23.1%, 20.5% and 12.9%, respectively. Compared to the control, introducing drought conditions reduced the mean of germination percentage, germination index, seedling vigour index and radicle length of yellow-coated seeds by 52.4%, 64.1%, 41.9% and 23.2%, respectively. Meanwhile, drought affected brown-coated seeds more than yellow-coated seeds. The results indicating that the seed quality of white clover seed lots with yellow-colored coats higher than the seed lots with brown-coloured coats. In agronomic practice, a larger proportion of yellow-coated seeds should be harvested to improve new stands successful establishment under environment easy to dry.
