ABSTRACT
A study was undertaken to analyse the effect of various concentration of GA3 and soaking period on seed germination of custard apple. The experiment was laid out in Factorial Randomized Block Design (FRBD) with three replications. The results of present investigation clearly showed that there were significant differences with respect to effect of different concentrations of GA3 and soaking period on seed germination of custard apple. The maximum germination percentage was maximum with the seed treatment of GA3 at 400 ppm. Regarding duration of soaking, soaking of seeds for 24 to 48 hrs gave early, maximum germination percentage of the seedlings. In respect of interaction effect , it was observed that soaking of seeds in GA3 400 ppm for 12 hrs gave maximum germination percentage and seedling height.
Thus, it can be concluded that seed treatment of GA3 at 400 ppm for 24- 48 hrs was helpful to get higher germination of custard apple seedlings.
Key words :
Annona squamosa, custard apple, Growth, germination, GA3, seedling, ppm.
