Gibberellins Contents in Leafy Fruitlets of Satsuma mandarin (Citrus
unshiu, Marc.) in Relation to Fruit Quality
Abstract:
Present studies were designed to find out the role of endogenous Gibberellin like compounds in production of low quality in leafy fruits of Satsuma mandarin. Gibberellin-like activity in the leafy and leafless fruitlets of Satsuma mandarin grafted on Troyer citrange, Sour orange and Trifoliate orange rootstock was tested with lettuce hypocotyl elongation test. Results showed that Gibberellin-like activity in the leafy fruitlets was considerably higher than the leafless fruitlets in Troyer citrange. Like wise Gibberellin-like activity in the leafy fruitlets of Satsuma mandarin grafted on Sour orange and Trifoliate orange was also higher than that of leafless fruitlets. Comparison of the leafy fruitlets indicated that maximum gibberellin like activities were noted in case of Trifoliate rootstock which was followed by Troyer citrange and Sour orange, respectively.
