Abstract

Foliar fertilization plays an important role in increasing the micro or macro element of fruits. The influence of paclobutrazol, boric acid and gibberellic acid on growth and quality of strawberry was investigated during the years 2011 and 2012. The experiment was conducted as a factorial experiment in a completely randomized design with 4 replications. Paclobutrazol (25, 50 and 100 mg l-1), boric acid (50, 150, 200 mg l-1) and gibberellic acid (50 and 100 mg l1) solutions were applied as foliar sprays and data were recorded for dry weight, number of runners, leaf area, number of flowers, length of the roots, length of flowering period, weight of primary and secondary fruits and number of their achenes, Tss, TA and vitamin C of the fruit. Results indicated that vegetative growth was reduced with paclobutrazol. The application of paclobutrazol increased number of flowers, weight of primary and secondary fruit, percentage of total soluble solids and and ascorbic acid, while reduced titratable acidity. Results indicated that gibberellic acid increased number of runners but had no effect on reproductive growth. Boron significantly enhanced the vegetative growth, number of flowers, fruit weight, vitamin C, and total soluble solid content of the fruits.
