Abstract:
It was established that the treatment of inflorescence of the table grape variety Cardinal by biological active substances - gibberelic acid (GA3) and α-naphtyl acetic acid leads to increase in the sizes and weights of clusters. Along with increase in the sizes, degree increase seedless berries and their durability on texture is observed. Productivity of vines increases in 1,3-1,8 times. We have established that for a table grape variety Cardinal optimal concentration of gibberellic acid is GA3-50 mg/l and GA3+ α-NAA-5 mg/l (ppm).
