Abstract
The stone of ber (Ziziphus mauritiana) cv. cola were size graded using round perforated metal sieves of size 28/64", 26/64", 24/64"and 22/64". Seed quality characters in terms of germination (%), root and shoot length (cm), dry matter production (mg 10 sl-1) and vigour index were more in medium sized stones compared to large and small sized stones. The maximum recovery percentage, number of seedlings produced per 100 graded stones with 24/64" round perforated sieve are recommended for production of better quality seedlings in ber.
