Abstract

Mangosteen (Garcinia man,ostana L.) seedlings widen were about six months old and _rown under part-ially snaded conditions were sprayed weekly for three weeks with different levels of 0,3 (0, 100, 200, 500, 1000 ppm). After 14 weeks, the treated manosteen seed-lings were evidently taller than the control plants and had ratner lon u-Termost inte•riodes. The effect of GA3 on girth was not significantly different from the control but for height and number of leaves the effect was sig-nificant. This was attributed to the great response of th stem to GA3 application and to the promotive effect of GA3 in cell division and elongation. Si0nificant differences betw,en the treatments were ouserved only wren height was considered. However, leaf abscission was observed with all the treatments; also cleat,. of seedlings was found to be associated wit► hiLner concentrations of GA3 (500 and 1000 ppm ).
