金沙江干热河谷番木瓜生态学研究

STUDIES ON THE ECOLOGY OF PAPAYA IN DRY AND HOT VALLEY REGION IN JIHSHA RIVER

本文对金沙江干热河谷区番木瓜(Carica papaya L.)进行了连续三年(1985至1988年)的生态学观察和探讨。树干横断面积、树高、果实纵径及果实大横径月均生长变化量与相应的月均温度和相对湿度之间呈直线相关,与日照时数之间无相关性。果实体积和小横径月均生长变化量与相应的月均温度、相对湿度及日照时数之间无直线和曲线相关性。

Basing on work of papaya (Carica papaya L. ) in the dry and hot valley region in Jinshalriver, the authors had been observin and exploring for the ecology in the last few years(1985-1988). The growing change of monthly average on the trunk area of the transection, the height and the fruit length of the direct —axis and the macro cross axie was directly correlative with the relative temperature and relative humidity, but not with the relative day hours. The growing change of monthely average on the fruit volume and length of the small aross axle was not the alinghning and curving correlative with the relative temperature.relative humidity and day hours.
