JASMONATES IMPROVE FLOWERING AT THE EXPENSE OF RUNNER PRODUCTION IN STRAWBERRY

Hydroponic strawberry production in greenhouses is becoming more common in Iran. However, there are several problems associated with it including low yield, poor fruit quality, misshapen fruits, and susceptibility to environmental stresses. Using plant growth regulators is an important means to ameliorate these problems. In this research the effect of foliar application of jasmonic acid (JA) at the rate of 0, 0.5, 1, 1.5 and 2 mM, and methyl jasmonate (MJ) at the rate of 0, 0.25, 0.5, 1.0 and 1.5 mM on flowering, and runner production of the strawberry cultivars ‘Paros’ and ‘Selva’ was investigated. Results indicated that both JA and MJ at the rate of 1.5 mM produced the greatest number of flowers and inflorescences per plant. JA at concentrations of 1.5 and 2 mM, and MJ at 1.5 mM significantly decreased the number of runners.
