Seed Source Variation in Black Siris (Albizia lebbek Benth.)

Variation with respect to different pod and seed characteristics among 20 seed sources from Punjab, Haryana and Uttaranchal was studied. Correlation coefficient among pod and seed characteristics, germination percentage and growth parameters of mother trees was also estimated. The correlation matrix revealed that statistically significant correlation exists between seed weight, seed width, and seed length. Germination per cent was positively correlated with number of seeds per pod. Highest germination percentage was found in Raipur seed source in Ropar Forest Division though there was a high variation in germination percentage among all the seed sources. Based on our finding it is suggested that the seeds of Albizia lebbek should preferably be collected from healthy and fresh pods.
