dc.description.abstractSeed germination study of bitter gourd varieties Pusa Do Mausmi and Pusa Vishesh under laboratory and field conditions using eight chemicals and three seed soaking durations was carried out in March and August, 2009. Analysis of variance revealed highly significant differences among the treatment effects for different characters in both the varieties for respective seed soaking durations. Test weight of sampled seeds was 17.99g (Pusa Do Mausmi) and 16.96g (Pusa Vishesh). In both sets of experiments varieties differed for all the characters in respective seed soaking durations under laboratory and field conditions where some interactions were also significant. The laboratory seed germination and seedling field emergence for both the sets of experiments and all the three seed soaking durations were found similar but field emergence was lesser than laboratory seed germination in all the treatments investigated. In both the sets of experiment GA3 50ppm followed by KCl (1%) and ZnSO4 (1%) gave significantly higher seed germination then the canal water control treatment in both the varieties. Pusa Vishesh had better germination than Pusa Do Mausmi, however, field emergence was at par in both the varieties. Field emergence (%) and field emergence index were recorded maximum with GA3 50ppm/boron 25ppm and or GA3 50ppm/KCl (1%) and KNO3 (1%) and ZnSO4 (1%). It was lowest with canal water and IBA 75ppm. The other associated parameters of seed quality i.e. seedling length (root/shoot), seedling fresh/dry weight, seed vigour index-I and II were also influenced by the chemical treatments and followed almost the same pattern as of seed germination and seedling field emergence.Seed soaking duration of 12h was better than 24 and 36 h seed soaking.The seed germination, field emergences/index, seedling size, and seed vigour index were reduced with aging of the seeds. The patterns of field emergence, which showed non-to-multi peaks was not consistent for the chemical response, seed soaking duration and also for the crop season. GA3 50ppm, KCl (1%) and KNO3 (1%) with 12h seed soaking appeared most promising for enhancing seed germination/field emergence of bitter gourd varieties.en_US
