Lanzhou University,Lanzhou,730000The difference between the spectral reflectance curves of healthy and diseased larch canopies is obvious.In this work,we chose the larch plantations as the study object.Firstly,we selected 14 larch canopy samples and measured their spectral reflectance and photosynthetic pigment contents.Then we selected 8 spectral parameters to set up a series of linear regression models.

So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.

因此，本试验以温度敏感性不同的瓜类作物为材料，研究了夏季自然条件下不同物种间在耗散过量光能的主要机制差异；探讨了它们对不同根际温度在根系活性氧代谢及地上部光合作用等方面的生理响应差异，所取得的主要结果如下： 1、在夏季晴天条件下，三种温度敏感性不同的瓜类作物：喜温的黄瓜，耐热性的丝瓜与热敏感的黑籽南瓜在气体交换、叶绿素荧光、光能分配及光合电子流对一天中温度与光照环境变化的响应上存在物种间差异和日变化特征。
