本文报导了对茶树鱼叶生理功能研究的初步结果。研究证明:鱼叶比同枝邻位真叶,光合作用功能无明显差异;鱼叶的呼吸强度低于真叶;新梢采摘后留下的鱼叶和邻位叶比,其光合值显著高于真叶。鱼叶的生化内含物除多酚类外,氨基酸、咖啡碱均高于真叶。鱼叶的气孔开张度低于真叶,最大开启度在下午16时,而真叶在上午10时。表明:鱼叶不是非正常叶,而是一种生理功能叶。 This paper reports the preliminary results on the physiological functions of tea leaves. The results showed that there was no significant difference in the function of photosynthesis between true leaves and true leaves of the same shoots. The respiration intensity of the leaves was lower than that of the true leaves. The photosynthetic rate of the leaves and the adjacent leaves remained after picking the shoots was significantly higher In true leaves. Biochemical content of fish leaves in addition to polyphenols, amino acids, caffeine are higher than the real leaves. The stomatal opening of the leaves is lower than the true leaves, with the maximum opening at 16 o’clock in the afternoon and the true leaves at 10 o’clock in the morning. Show that: the fish is not a non-normal leaves, but a physiological function of leaves.
