摘要: 测定南亚热带丘陵地马尾松、湿地松和加勒比松光合速率、蒸腾速率、日同化量和水分利用效率的变化。结果表明,3种松树光合速率和蒸腾速率都具有明显的日变化和季节变化,夏季的光合速率和蒸腾速率最高,冬季最低;加勒比松的平均日同化量为9.34g·kg-1、平均水分利用效率为159.75μmolCO2·g-1H2O,高于其它树种;湿地松最低。加勒比松是很好的引种树种,更适合在当地推广.

Abstract: The photosynthetic rate, transpiration rate, daily CO2 assimilation quantity and water use efficiency of Pinus massoniana, Pinus elliottii and Pinus caribaea in hilly regions of south subtropics of Guangdong were measured. The photosynthetic and transpiration rate of test pines displayed daily and seasonal variations,with the maximum in summer and the minimum in winter. Among the test pines, P.caribaca had the highest annual average daily CO2 assimilation and water use efficiency,indicating that is more adaptive to the local environment,and should be widely popularized in this study area.

Key words: Pine, Photosynthetic rate, Transpiration rate, Water use efficiency, evolution law, hydrological variability, inheritance theory, inconsistent., hydrological gene, principle of hydrology
