摘要

Seed size is a trait of the plant that affects seed germination and seedling survival.This study aims to assess the growth response of J.curcas to different seed sizes.A pot experiment was conducted to evaluate the effects of J.curcas seed sizes on the seedling vigour and seed component.The seeds were fractioned into three sizes visually into: large, medium and small and by 1000 seeds weight (SW).Seedling vigour was assessed by: germination % (G%), seedling length cm (SL), seedling vigour index, SVI, seedling growth rate, SGR, and speed of germination, SOG as well as proportion of cake, shell and oil content (OC) expressed as% of the seed.Results obtained shows that G% and the SOG were not affected by seed sizes but by other factors within the seed.However, seedling vigour expressed as SL, SVI and SGR increased significantly (P 0.05) with increase in seed sizes.Proportion of cake, shell and oil component of J.curcas seeds increased with increasing seed sizes while 60% of the seed is made up of the cake from where the oil is extracted.Dry matter yield, DMY significantly (P 0.05) increased with increase in seed size from 6.41 g/plant in large seeds to 2.61 g/plant in small seeds.There is positive and strong significant correlation between, SW and DMY (r = 0.91**), yield increase (r = 0.82**), OC (r = 0.85**), % cake (r = 0.94**).Findings revealed that larger seed had higher potential of producing vigorous plants with eventual high crop yield and higher OC.
