Influence of soaking time and PGR on seed germination and seedling growth of tamarind (Tamarindus indica L.)

Abstract

The study investigated effect of different soaking and PGRs on seed germination and growth of Tamarind and was conducted at college of horticulture and research station, Sankara, Patan, Durg (C.G). The experiment was laid out in Factorial Completely Randomized Design with two factors, factorial arrangement having three replications. Data were recorded for days of initiation of seed germination, days required for 50% germination, germination percentage, number of leaves per seedling, seedling length, stem girth, survival percentage and mortality percentage of the seedling. Seeds with soaking time 24 hours + 200 ppm GA3 (S3P2) showed earliest germination (6.9 DAS), while control took maximum days (17.8 DAS). Maximum germination percentage (95.0) was recorded for Seeds with soaking time 24 hours + 200 ppm GA3 (S3P2) along with maximum no. of leaves per seedling (17.1), maximum stem length (60.1), more stem thickness (2.98) and maximum survival percentage (91.3) at 90 DAS. In conclusion, seeds soaked for 24 hours in GA3 200 ppm have out perform all the germination attributes, plant growth attributes and survival parameters whereas control (S0 p0) had shown the poorest of them all.
