Description Seed dormancy is a major limiting factor constraining commercial cultivation of spine gourd and hence the present study was undertaken to identify better environment for the germination. The germination of fifteen spine gourd genotypes, grown at three different locations was analyzed. All the combinations were tested under optimal conditions for germination. We have evaluated the seed germination response to different environment along with different physical factors which influence seed germination and found that the genotype, G10 did perform well under all the three environments which was followed by G2, G4, G8 and G12. Among the environments, E2 was a best suited environment for germination and E1 is at par with E2. Germination deciding factors like soilpH, temperature, N, P, K and organic matter content did affect germination in some extent and these factors can be additive, synergistic or inhibitory, depending on the combination, providing an almost infinite spectrum of dormancy levels. The location caused the greatest variation across all the experiments and the impact was greater for germination than for vitality. The results should encourage breeding for seed vitality and some reconsideration of provenance effects on seed vitality.
