对４ 种不同类型越桔叶片光合作用温度特性的比较结果表明：红豆越桔、矮丛越桔、半高丛越桔和高丛越桔叶片净光合速率（ＣＯ２） 的变化范围分别在５－５８ ～８－２８、５－３０ ～７－４８ 、４－９５ ～７－２４ 和４－０６ ～７－１８ μｍｏｌ／（ｍ２·ｓ），其光合作用温度下限分别为０ ℃～３ ℃、２ ℃～４ ℃、３ ℃～６ ℃和３ ℃～６ ℃；其温度上限分别为４２ ℃～４５ ℃、４２ ℃～４５ ℃、４４ ℃～４６ ℃和４４ ℃～４７ ℃，其最适温度范围分别为１８ ℃～２５ ℃、２０ ℃～２７ ℃、２５ ℃～３０ ℃和２５ ℃～３３ ℃；叶片量子产额在不同温度条件下均呈单峰曲线型变化，红豆越桔、矮丛越桔、半高丛越桔和高丛越桔叶片量子产额的峰值分别出现在２０ ℃、２５ ℃、２５ ℃和３０ ℃，并表现为红豆越桔＞ 矮丛越桔＞ 半高丛越桔＞ 高丛越桔；从光合与呼吸ＣＯ２ 交换比值来看，红豆越桔和矮丛越桔的最高值分别出现在２０ ℃和２５ ℃，而半高丛越桔与高丛越桔在１５ ℃～３０ ℃时均表现出较高的比值；在光合适宜温度范围内，４ 种类型越桔叶片光合作用的光补偿点和光饱和点表现为红豆越桔＜ 矮丛越桔＜ 半高丛越桔＜ 高丛越桔。 The results of the comparison of the photosynthetic temperature characteristics of four different types of bilberry leaves showed that the net photosynthetic rate (CO2) range of the leaves of red bean, short bush bilberry, semi-high bilberry and high bilberry was 5- 58 ~ 8-28,5-30 ~ 7-48, 4-95 ~ 7-24 and 4-06 ~ 7-18 μmol / (m2 · s), respectively. The lower limit of photosynthesis temperature was 0 ℃ ~ 3 ℃, 2 ℃ ~ 4 ℃, 3 ℃ ~ 6 ℃ and 3 ℃ ~ 6 ℃. The upper limit of temperature is 42 ℃ ~ 45 ℃, 42 ℃ ~ 45 ℃, 44 ℃ ~ 46 ℃ and 44 ℃ ~ 47 ℃, respectively. The temperature range was from 18 ℃ to 25 ℃, from 20 ℃ to 27 ℃, from 25 ℃ to 30 ℃ and from 25 ℃ to 33 ℃, respectively. The leaf quantum yield showed a single peak curve under different temperature conditions, The peak of quantum yield of the leaves of the cluster broomcorn, the bracteoleum biloba and the tall bush breeze appeared at 20 ℃, 25 ℃, 25 ℃ and 30 ℃ respectively, Orange> semi-high bilberry> high bilberry; from the photosynthetic and respiratory CO2 exchange ratio, the highest values ​​of red bean bark and short bilberry appear at 20 ℃ and 25 ℃ respectively, High bush bilberry showed a higher ratio at 15 ℃ ~ 30 ℃. The light compensation points and light saturation points of photosynthesis in the four types of bilberry leaves were the best under the proper photosynthetic temperature range Orange
