PGR gibberellic acid 90% Tc GA4 GA7 plant growth regulator was discovered during the research of rice blight, and it refers to a generic term for a class of compounds with a gibberane skeleton that can stimulate cell division and elongation. Gibberellin is a plant growth regulator, which can promote crop growth and development, make it mature earlier, increase yield and improve quality.
PGR gibberellic acid 90% Tc GA4 GA7 plant growth regulator widely distributed in quilts, gymnosperms, ferns, brown algae, green algae, fungi and bacteria, and it is mostly found in vigorous growth parts, such as stem ends, young leaves, root tips and fruit seeds. The type, quantity, and state (free state or combined state) of igibberellin vary according to the stage of plant development.
Treating dormant potatoes with PGR gibberellic acid 90% Tc GA4 GA7 plant growth regulator of 2 ~ 3μg · g can make them germinate quickly, which can meet the needs of planting potatoes multiple times a year. This is becauseGibberellin can induce the synthesis of α-amylase, protease and other hydrolases, and catalyze the degradation of the storage materials in the seeds for the development and development of the embryo.
The differentiation of flower buds in some higher plants is affected by the length of sunlight (ie, photoperiod) and temperature. If PGR gibberellic acid 90% Tc GA4 GA7 plant growth regulator is applied to these unvernalized plants, flowering can be induced without low temperature process, and the effect is obvious. In addition, Gibberellin can also replace some long-day plants to induce flowering in some long-day plants.
The most prominent effect of PGR gibberellic acid 90% Tc GA4 GA7 plant growth regulator on plants is to stimulate the elongation of the stem, which significantly increases the height of the plant, especially the elongation of the flower stem. Gibberellin does not change the number of nodes, but gibberellin has the effect of stimulating plant cell elongation and promoting cell division.
PGR gibberellic acid 90% Tc GA4 GA7 plant growth regulator is also involved in the process of plant tolerance to many abiotic stresses. For example, under the environmental stresses of low temperature, high salt, drought and hypertonicity, plants can slow down their growth by adapting to gibberellin and adapt to the external environment. On the contrary, plants also generate escape mechanisms by increasing gibberellin To get rid of environmental stress such as flooding.
PGR gibberellic acid 90% Tc GA4 GA7 plant growth regulator can not only promote stem elongation, but also promote leaf growth and expansion, and even change leaf shape. while gibberellin is sprayed during the topping stage of the tobacco leaf, and the parietal leaf is opened later Have a greater impact. Can promote the top tobacco leaf to stretch, smooth, reduce wrinkles, and can increase the width of the top tobacco leaf.
