Studies on The Effect of GA3 on Growth and Development of some Citrus Rootstocks

The present study was planned to follow three citrus rootstocks in response to different concearations and petterns of gibberellin application at different stages of seedling development upto the usual age of budding. Sour orange, rough lemon and trifoliate orange were used in the study to represent different levels of growth vigour within the citrus rootstock. Growth vigour is thought to be considered of close relationship with the endogenous balance of plant orginization and responese.
