 ABSTRACT

The present investigation was conducted under greenhouse condition with an aim to study the effect of pre sowing treatments like aging [A1 (8 months old seeds) and A2 (new seeds)], scarification [S1 (manual scarification with sandpaper) and S2 (ultrasonic sound)] and different treatments [T1 (GA3 100 ppm), T2 (GA3 300 ppm), T3 (KNO3 at 2%), T4 (cow dung for 24 hours), T5 (cow dung for 48 hours), T6 (ethrel 100 ppm) and T7 (control)] on seed germination and its parameters in sandalwood. But aging factor was not considered as the number of germinated seeds is observed to be very less. The results indicated that 8 months old seeds had poor germination because of loss of viability. Observations viz., germination per cent (%), time taken for initiation of germination (TTIG), time taken for completion of germination (TTCG), speed of germination, mean weekly germination, root length of seedling (cm), shoot length of seedlings (cm), seedling length (cm), collar diameter (mm), seedling fresh weight (mg), seedling dry weight (mg), seedling vigour index (length) and seedling vigour index (mass) were analyzed by completely randomize design (factorial) in three repetitions. Manual scarification with sandpaper (S1) produced significantly the earliest seed emergence and also resulted superior response in all the observations. Among different treatments GA3 300 ppm (T2) was best for 9 observations out of 13 observations. The treatment combination S1T2 (manual scarification with sandpaper treated with GA3 @ 300 ppm) noted the earliest seed emergence and relatively the maximum germination percent.
