THE EFFECT OF GROWTH-REGULATING SUBSTANCES ON THE ASSIMILATORY SURFACE OF TABLE GRAPE VARIETIES.
Keywords:
grapevine, table varieties, assimilating surface, Falgron, growth regulator, leaf area, photosynthesis.Abstract
This study investigates the effect of the growth regulator Falgron at different concentrations on the assimilating surface of leaves in table grape varieties — Khusaine Belyi, Rizamat, and Khusaine Kelin Barmak. The results showed that a concentration of 40 mg/l significantly enhanced leaf growth and increased the total assimilating surface area by 25–35% compared to the control. However, at 60 mg/l, a decrease in leaf growth was observed. The optimal concentration for improving vine leaf development was determined to be 40 mg/l of Falgron.
