<p>Red chili is a very important horticultural commodity in Indonesia having low productivity and quality. Cultivation method needs to be improved including the use of exogenous growth hormones. The purpose of this study was to determine (1) the optimum concentration of IAA and GA growing hormones from isolate B6.2 in stimulating plant growth and improving the quality of large red chili fruit; (2) molecular identity of the B6.2 bacterial isolate. The growth hormone content of B6.2 isolates using HPLC obtained 0.49 ppm IAA and 64.53 ppm GA. The growth hormone potential test on the growth and quality of chili was carried out with a concentration of 1, 3, 5 ml/l, while water and synthetic hormones was used as negative and positive control, respectively. The experimental design used was a Complete Random Design with the foliar spray application to the plant canopy three times during the growth period. The results showed the best concentration in increasing plant height, fruit weight, shooth wet, and dry weight compared to controls at the age of 76 days after planting (dap) was a concentration of 5 ml/l, with the values of 71.7±0.9 cm , 94.7±0.3 g, 11.5±0.43 g, and 1.4±0.09 g, respectively. The molecular identification showed that B6.2 isolate was classified as Bacillus vallismortis with 100% homology. The growth hormone from isolate B6.2 has the potential to increase growth and production of red chili plants.</p>

Significant results were obtained from most studied parameters. The results indicated that cultivars had significant response on some of vegetative growth and yield parameters of pea, the best results were recorded from Utrillo cultivar. Moreover, foliar spraying of Nitrphenolates had significant influence on vegetative parameters, the highest significant result of leaves and branchesnumber (110.747 and 2.694 respectively) were recorded from (1ml.l-1). While, the best results of vegetative growth fresh weight and leaf chlorophyll content were obtained from 0.2 ml.l-1treatment. Foliar spray of Nitrphenolate also increased significantly yield parameters, where the highest values of number of seeds.pod-1, yield per plant, plat and hectare (6.000, 0.168kg, 1.009kg and 1.681ton respectively) were recorded from 0.2 ml.l-1 treatment compared with the control. Meanwhile, there was the significant response of cultivars to foliar application of Nitrophenolates on most vegetative growth and yield components and were recorded for both cultivars especially Nihal.

Abstract An experiment was carried out in the Laboratory of Seed Technology-College of Agricultural Engineering Sciences - University of Baghdad – Iraq, to studying the stimulation of maize seeds by soaking with selenium and chitosan to improve the vigour and viability of seeds. By using factorial experiment according to the Complete Random Design (CRD) with three replications. The seeds of two synthetic cultivars of maize (Baghdad 3 and Buhoth 5018) were soaked in selenium solutions at two concentrations (2 and 5 mg L-1), and chitosan (100 and 500 mg L-1) for 10 hours, as well as the two control treatments, which were dried seeds (without soaking) and the seeds soaked in distilled water. Results are shown that low concentration of 2 mg L-1 give highest mean were recorded in the percentage of germination in the first and final counts, the mean time germination, length of root and the plumule, the seedling vigour index, germination speed, and dry weight of the seedling. Seeds soaking with the solutions containing chitosan at both concentrations did not give significant results compared to the selenium treatments, both cultivars differed significantly in some germination characteristics and the vigour and viability of the seed: (length of root and the plumule, dry weight of the seedling). The results also showed a significant effect of the interaction between seed soaking treatments and cultivar on all studied traits. We conclude from this study that treatments of stimulating seeds by soaking them with distilled water and solutions of selenium and chitosan positively affected germination and its characteristics, so we recommend using low concentrations of selenium and chitosan to improve seed germination, vigour, and viability of the seedling.

The present study was performed during two successive seasons 2019 and 2020 to investigate the effect of the soil application of fulvic acid (FA), seaweed extract (SE), and their different combinations on vegetative growth, yield, and fruit quality of six-years-old guava (Psidium guajava L.) cv. ‘Maamoura’. The trees were planted 4 × 4 m2 apart in clay soil under a flood irrigation system. They were treated three times starting from mid-March with one-month intervals with the following treatments: Control (water only), 3 and 4 g/L FA, 3 and 4 g/L SE, and their different combinations; 3 g/L FA + 3 g/L SE, 3 g/L FA + 4 g/L SE, 4 g/L FA + 3 g/L SE, and 4 g/L FA + 4 g/L SE. The results clearly showed that the application of FA or SE solely or in combinations increased shoot length and diameter, as well as leaf chlorophyll compared with the control. The treatments also increased fruit set percentage, fruit yield, and fruit physical and chemical characteristics such as fruit weight, size, TSS%, total reduced and non-reduced sugars, as well as leaf mineral content, while they decreased the fruit acidity compared with the control in the two seasons.

Leizhou Peninsula in South China is facing a serious water shortage problem because of the special regional and geological conditions. As a kind of low water requirement crop, pineapple has been popular in lateritic soil. However, the physical characteristics of Lateritic soil such as too cohesive, impervious, low content of organic matter, and seasonal arid often bring some problem to pineapple cultivation. Seasonal iron deficiency can be easily observed from April to July. The effect of foliar spray of iron sulfate (with concentration of 0, 0.5%, 0.75%, 1%) on the fruit growth and quality of pineapple cv. Yellow Mauritius were studied in this research. Results showed that there were no significant difference (p>0.05) on the fruit weight, longitudinal diameter, transverse diameter among all the treatment. 0.75% treatment increased the fruit weight to 6.08% and decreased crown weight significantly. Both 0.75% and 1% iron sulfate treatment not only enhanced vitamin C extremely significantly, but also improved the aroma quality significantly with the increase of total esters, especially in the content of hexanoic acid methyl ester, 3-(methyl tio) propanoic acid methyl ester and 2-methylbutanoic acid methyl ester. The content of these 3 esters above were all extremely significantly higher than control, which means much stronger pleasant aroma. Hence, 0.75% was the optimal concentration of foliar spray with iron sulfate in pineapple cv. Yellow Mauritius.

The role of arbuscular mycorrhizal fungi in sweet oranges is well known, but the function of their secondary metabolite, especially the easily extractable glomalin-related soil protein (EE-GRSP), an active fraction of glomalin, is still unclear. The proposed study aimed to analyze the field response of foliar application of exogenous EE-GRSP on tree mycorrhizal development and fruit quality of two sweet orange (Citrus sinensis L. Osbeck) varieties viz., Lane Late Navel (LLN) and Rohde Red Valencia (RRV). Application of EE-GRSP significantly increased the root mycorrhizal colonization and soil mycorrhizal hyphal length in both the sweet orange varieties. The external quality of fruits (fruit weight, polar diameter, and equatorial diameter) also improved in response to foliar application of EE-GRSP in both sweet orange varieties. However, EE-GRSP treatment showed no change in fruit soluble solid content, while it increased the Vc content, solids-acid ratio, fructose, glucose, and sucrose content of sarcocarp in the two sweet oranges varieties. The LLN variety treated with EE-GRSP recorded significantly higher N, P, K, Fe, and Si content of sarcocarp as a mark of nutritional quality, while the RRV variety treated with EE-GRSP displayed a higher concentration of nutrients like Cu, Fe, Si, and Zn in the sarcocarp as compared with the corresponding non-treated control. To the best of our knowledge, this is the first report regarding the improvement in fruit quality of late-ripening sweet oranges (especially LLN) in response to foliar application of EE-GRSP as another potential biostimulant.

Abstract Growth and flowering responses of Pelargonium × hortorum L. H. Bailey ‘Ringo Deep Scarlet’, Tagetes erecta L. ‘Inca Orange’, Viola × wittrockiana Gams. ‘Blue Shades’, Impatiens × ‘Zenith’ and Salvia farinacea Benth. ‘Victoria Blue’ to uniconazole applied at the seedling stage were evaluated at the end of production and 5 to 7 weeks after transplanting into the landscape (geranium, impatiens and salvia only). A drought stress evaluation was also conducted. Response to uniconazole varied with species, sampling date and uniconazole concentration. Growth of all species was suppressed when measured 4½ to 8½ weeks after treatment (WAT), and stress tolerance of all species except marigold increased with increasing concentrations of uniconazole. Flowering generally was delayed with uniconazole. Impatiens and geranium treated with 10 ppm or less of uniconazole were similar in height to nontreated plants 5 to 7 weeks after being transplanted; at this time, uniconazole had no effect on plant height or shoot dry weight of salvia. Daminozide applied once as a 5000 ppm foliar spray was not effective in suppressing vegetative growth of any of the tested species.

Twenty-eight-year-old `Starkrimson Delicious' and 10-year-old `Fullred Delicious' apple (Malus domestics Borkh.) trees were spur-pruned in 1986 and 1987 and/or treated with 500 mg BA + GA4+7/liter in 1986 in an attempt to improve spur growth and increase fruit weight. All treatment combinations generally failed to improve yield or fruit size. BA + GA4+7 reduced yield and fruit weight and increased the number of pygmy fruit in 1986, but had little effect on fruiting or vegetative growth for 3 years after treatment. Spur-pruning reduced spur density in 1986 and 1987 and increased yield, but not fruit weight, in 1987. Although spur-pruning improved spur length, spur bud diameter, leaf area per spur, and leaf dry weight per spur, fruit weight was not improved. Chemical names used: N-(phenylmethyl)-1H -purine-6-amine [benzyladenine (BA)]; gibberellin (GA4+7).
