我们于1985年秋对辽宁5个主栽山楂品种甜水、秋金星、西丰红、辽红、磨盘的蒸腾强度、叶绿素含量及枝条的呼吸强度进行了测定,结果表明品种间有明显差异。在同一立地条件下,蒸腾强度大致在4.0～6.7g·dm~(-2)·hr~(-1)的范围内,以磨盘最高,甜水最低;叶绿素含量大致在2.750～4.010mg·g~(-1)之间,以西丰红为最高,秋金星最低,呼吸强度大致在0.165～0.330mgCO_2·g~(-1)·hr~(-1)的范围内,以甜水为最高,西丰红最低。
In the autumn of 1985, we measured the transpiration intensity, chlorophyll content and respiration intensity of five main varieties of hawthorn in Liaoning Province, such as sweet water, autumn Venus, Xifenghong, Liaohong, and Mopanshan. The results showed that there were significant differences among varieties. Under the same site conditions, the transpiration intensity was in the range of 4.0 ~ 6.7g · dm -2 · hr -1, with the highest disc and the lowest sweet water, and the chlorophyll content was about 2.750 ~ 4.010mg · g ~ (-1), Xifenghong was the highest, autumn Venus was the lowest, and the respiration intensity was in the range of 0.165-0.330mgCO 2 · g -1 (-1) hr -1, with sweet water being the highest. Xifeng Red lowest.
