Detection of endogenous gibberellins and their relationship to hypocotyl elongation in soybean seedlings. No difference was detected at the first evaluation with regard to the root collar diameter of plants Table 1. The Bonzi should help tame the Dalat. Share This Page Tweet. Since seeds in the control treatment were imbibed for the same time, under the same conditions, the treatment methodology can not be hold responsible for the decrease observed in the number of emerged plants. These tendencies persisted at the third evaluation, but the differences between treatments disappeared, demonstrating that the effects provided by GA are short-lived, since no effect of the foliar application of GA 3 was observed for this evaluation. Uncle BenJun 4, Effect of gibberellic acid on ion uptake selectivity in pea seedlings. Aluminun inhibiton of shoot lateral branches of Glycine max and reversal by exogenous cytokinin.

Jaiswal. Gibberellins (GA3, GA4+7, GA7 and GA9) induce male flowers on female plants of Cannabis sativa. This is, depending on concentration, partially or fully.
To better understand the role of these compounds, a pot experiment was carried out to study effects of GA 3 and cytokinin on the vegetative growth of the soybean.
Since root dry matter was not affected as well, it is fair to infer that the roots of treated plants became thicker because they had shorter root lengths and similar amounts of root dry matter data not shown.
Gibberellic Acid(growth hormone) .. effects on marijuana Rollitup
Deactivation of bioactive GAs has recently been shown to also occur through methylation of bioactive GAs Varbanova et al. The effect of GA 3 on root growth is indirect, by means of its effect on the growth of the aerial part, because of the action exerted by GA 3 on cell elongation Tanimoto, Papaya is a trioecious species with a pair of nascent sex chromosomes controlling sex type; females are XX, males XY, and hermaphrodites XY h Ming et al. In a comparison against 34 commonly consumed fruits, papaya ranks number one in many categories including vitamin A and C, potassium, folate, niacin, thiamine, riboflavin, iron, and calcium Liebman,

|No difference, however, was found in dry matter mass for the aerial part data not shown that would justify this smaller growth of the root system, thus eliminating this hypothesis.
Gibberellin is a major phytohormone that functions to not only promote normal growth and development, but it is also able to affect sex expression in many plant species reviewed by Khryanin, So it may possibly help to shorten the veg cycle, but the risk of herms and extreme stretching limit its use for indoor cult and probably outdoor as well.
