Abstract: Different seedtime was adopted with different maturity genotype cotton,in order to study the dy-namic characteristics of material accumulation in different temperature and sunlight. The results showed that the accumulation of nutritional organ of early-mid maturity was more than that of middle maturity, and the accumu-lation of nutritional organ of middle maturity was more than that of early maturity. The earlier the cotton ma-ture,the earlier of the key period of material accumulation. The suitable sowing time is favorable for the materi-al accumulation in three maturity cottons.On the other hand, the earlier maturity cotton accumulates more ma-terial than the later maturity cotton in the reproduction organ. The earlier sowing date is, the quicker and more material accumulates. The result offers theoretical basis for the establishment of growth mechanism model and production adjustment and control for cotton.

Key words: Maturity, Sowing date, Dry material, Accumulation
