一、前言近年来,以经济指标为主要因子,从油茶物种中选育出部分油茶优树,这些优树受遗传和环境的综合影响使得茶油产量低。油茶产量的高低主要是植物对光能刊用的强弱和植株本身经济系数的高低。光合,呼吸和蒸腾强度是植物生命活动中最本质的三个生理因子。研究它们的变化规律是为油茶良种选育和速生丰产栽培技术提供依据,我们于1981年至1982年,对优树进行了光合、呼吸和蒸腾强度等生理性状方面的测定。现综
I. Introduction In recent years, with economic indicators as the main factor, some elite trees of Camellia oleifera were bred from Camellia oleifera species. The yield of tea oil was low due to the combination of heredity and environment. The level of oleifera production is mainly the strength of plants published on the light energy and the economic level of the plant itself. Photosynthesis, respiration and transpiration intensity are the three essential physiological factors in plant life activities. The study of their variation is to provide the basis for seed selection of elite tea and fast-growing and high-yielding cultivation techniques. From 1981 to 1982, we measured the physiological characteristics of elite trees such as photosynthesis, respiration and transpiration. Now comprehensive
