Effect of natural ageing on germination and seedling vigour of Teak (Tectona grandis Linn. f.) drupes

摘要

A study was conducted to find the effect of natural ageing on the germination and seedling vigour of fresh, one and two years-old teak drupes (Fruit with seed). The fresh, one and two year-old drupes were allowed for germination under open and mist chamber conditions following soaking and drying of drupes for 6 days at an interval of 12 hrs recorded 8, 37 and 51 per cent and 3, 40 and 50 per cent germination respectively. The total number of seedlings also reflected the same trend as that of germination. Seedlings from one and two year's old-drupes emerged early in mist chamber (10 days) than in open condition (12 days). Seedlings from one and two year-old drupes also exhibited better seedling vigour than fresh drupes.
