Gibberellins act to overcome dormancy and increase the germination rate of seeds several species, including genus Annona. Considering that Annona have a high lipid content few sugars, degradation such reserves from application gibberellins has not been described so far. This study aimed evaluate how different gibberellic acid (GA3) concentrations acts on sugar pattern during atemoya (Annona x M...

Induction of sprouting is widely used in Solanum tuberosum tubers to reduce the sprout growth time. The main objective this article was evaluate effect different concentrations gibberellic acid (GA3), ethanol, and hydrogen cyanamide (Dormex) on budding buds, length, number sprouts L. var. Cecilia tubers. Previously disinfected were immersed three inducers at placed two peat-based substrates (TS...

Crop yield is the ultimate manifestation of all physiological changes crops and external environmental influence. A controlled study was conducted to investigate effects exogenous gibberellin on morphological characteristics formation sesbania pea grown in saline soils. Seeds were presoaked with four levels Gibberellin (GA3) solutions (0, 202.1, 404.2 606.3 µM) for 6 h, then manually direct-sow...

A study was conducted to determine the optimum concentration of benzyladenie (BA) and gibberllic acid (GA3) to break the dormancy of gladiolus corms in relation to storage period and to find out the effect of BA and GA3 on growth and development of gladiolus corm and cormels. The effect of GA3 on dormancy breaking was most pronounced in the 100 ppm treatment being 26.93 days while in the water ...

Seeds of the plant Eucommia ulmoides Oliver, have prominent dormant characteristics. In present study, seed dormancy and germination E. were investigated by treating them with exogenous GA3 different water temperatures. The results revealed that warm soaking treatments beneficial to breaking seeds. rate seeds treated 50℃ was 84.67%. comparison, 300 mg·L-1 had only a 45%. This low resulted proba...

Polyamines (PAs) are involved in various developmental processes, especially plant flowering. Their significant influences have been established; however, the exact mechanism by which PAs regulate flowering remains unclear. To explore PA metabolism flowering, gibberellic acid (GA3, 0~2400 mg L?1) and spermidine (Spd, 0~1 mM) were applied alone or combination during early stage of flower bud for...

High transformation efficiency is a prerequisite for study of gene function and molecular breeding. Agrobacterium tumefaciens-mediated transformation is a preferred method in many plants. However, the transformation efficiency in soybean is still low. The objective of this study is to optimize Agrobacterium-mediated transformation in soybean by improving the infection efficiency of Agrobacteriu...

two experiments were performed for in vitro establishment, proliferation and shoot growth in axillary bud explants of sebri pear cultivar. in the first experiment, the effect of different concentrations of iba(indole-3-butyric acid) on explants’ establishment was evaluated. in a second experiment, the influence of several combinations of pgrs (plant growth regulators)on shoot proliferation and ...

P. aegyptiaca is one of the most destructive root parasitic plants worldwide, causing serious damage to many crop species. Under natural conditions P. aegyptiaca seeds must be conditioned and then stimulated by host root exudates before germinating. However, preliminary experiments indicated that TIS108 (a triazole-type inhibitor of strigolactone) and fluridone (FL, an inhibitor of carotenoid-b...
