Abstract: Ecological experiments of wheats was arranged in Lasa during 1982—1985. Liaochun 6 is a typical spring wheat, on the other hand, Taishan 4 is a winter variety. Heading and maturation were postponed, so were the growth periods and periods from sowing to maturation for wheats in Lasa. The low temperature was an important influential factor. Plant height of wheats was higher in Lasa, because growth periods was longer. The difference of temperature between day and night was bigger, the night temperature was lower, and the radiation of sun was stronger than most places in China, this contributes to the bigger weight of the seed.
