胡杨叶片生理特性的适宜采样量研究
Appropriate Sampling Quantity for Detecting Physiological Characteristic of Populus euphratica Oliv.Leaves
摘要
Abstract
Objective] The aim was to discuss influencing factors of field experiment.[Method] Selecting Populus euphratica from typical section Arakan in the lower reaches of the Tarim River, collecting leaves from 3layer, the FMC, EWT and chlorophyll content were meas-ured, differences of leaf moisture content at various levels were discussed , as well as the optimal sampling quantity which can represent aver-age leaf moisture content and chlorophyll content, the change of leaf moisture content and chlorophyll content within a day was analyzed.[Re-sult] Libra over one thousand scale precision could satisfy the demand of measuring a piece of leaf weight , ice bag preservation duration could meet the demands of field experiments; there was significant difference in leaf moisture content ( P<0.01 ) .FMC and EWT had low rate of changes between 15 and 20 leave samples: we should sample leaves from 3 leaf layers and 15 leaves per layer.There were insignificant( P>0.05) correlation between 5, 10 and 15 leaves, we just need to measure 5 leaves as chlorophyll content.FMC and EWT fluctuated within a day, while the chlorophyll content remained stable(within 1.5 SPAD).[Conclusion] The study can provide reference for field experiment of Populus euphraitca, also provide research on large-scale inversion of physiological state of Populus euphratica.关键词
