大豆生态研究Ⅸ.温度动态与野生大豆（G.Soja）生长发育关系的研究

STUDY ON SOYBEAN ECOLOGY Ⅸ. RELATIONSHIP BETWEEN TREND OF TEMPRATURE AND GROWTH AND DEVELOPMENT OF WILD SOYBEAN (Glycine soja)

摘要:

据公主岭, 泉州试验结果: (1)气温7.5℃以下停止营养生长。(2)气温7.6~25.5℃之间, 气温上升促进营养生长, 气温下降抑制营养生长。(3)在长光和控制长光下, 气温25.6℃以上促进营养生长。在控制短光下, 气温25.6℃以上抑制营养生长。在短光下, 气温23.5~25.5℃促进生殖生长; 气温25.6~27.9℃促进营养生长>促进生殖生长; 气温>28℃促进营养生长。(4)气温在自然光照线下抑制发育。(5)展开叶感光效应上递3节, 气温持续25.6℃以上, 未展开叶生长速度加快, 与展开叶感光效应上递3节失调, 反应高温抑制营养生长。(6)累加逐日平均温度28℃以上, 反应超高温抑制发育。

Abstract:

Bagsed on the result of experiment in Gongzhuling and Quanzhou, it was found that 1. The vegetative growth stops when temperature is below 7.5℃. 2. When temperature is between 7.5-25.5℃, the increase of temperatgre promotes the vegetative growth, while the, decrease temperature restrains the vegetative growth, 3. Under long daylength and controlled long daylength, the vegetative growth is promoted when temperature is over 25.6℃;Under controlled short daylength, the vegetative growth is restrained when temperattlre is over 25.6℃, Under short daylength, the temperature of 23.5-25.6℃promotes reproduvtive growth; when temperature is 25.6-27.9℃, vegetative growth > reproductive growth; vegetative growth is promoted when temperature is over 28℃, and 28℃ is the temperature restrains development. 4 Development is restrained when temperattlre is below the line of natural light. 5. The response to photoperiod of unrolled leaf goes up three nodes. When temperature is colltinuously over 25.6℃, the growth speed of rolled leaf accelerates, the response to unrolled leaf is imbalanced, this reflects that high temperatLlre restrains vegetative growth. 6. Development is restrained when accumulated average temperatLlre is over 28℃, this reflects that Super high temperature restrain development.
