A review on impact of GA3 application on strawberry cultivation

Abstract

Strawberry (Fragaria × ananassa Duch.) is a temperate fruit which bears aggregate fruits and responds well to plant growth regulators (PGRs). A range of varieties have been developed which are commercially being cultivated under subtropical climate as well. Application of PGRs particularly GA3 has been commercially recommended for cultivation of strawberry. Literatures are available which have endorsed application of GA3 at 10 to 150ppm concentration for various varieties like Pusa Early Dwarf, Senga Sengana, Missionary, Chandler, Sweet Charlie, Camarosa etc. These varieties have responded well in terms of better plant growth, runner production, flowering and fruiting enhancement, yield and quality improvement in strawberry after GA3 treatment. A direct correlation has been reported by many authors in between GA3 concentration and these parameters.
