中文摘要:以8年生的桃树枝条为试材,采用通径分析方法对电解质渗透率(EL)法和电阻抗图谱(EIS)法测定的桃树抗寒性与生理指标(脯氨酸含量、可溶性糖含量、淀粉含量、含水率)的关系进行分析。结果表明:EIS参数胞外电阻率(re)测定的抗寒性与生理指标关系中,脯氨酸含量、可溶性糖含量直接通径系数分别为-0.35(P<0.05)和-0.61(P<0.05),含水率的间接通径系数为0.53(P<0.05);EL法测定的抗寒性与生理指标关系中,脯氨酸含量、含水〖JP〗率直接通径系数分别为-0.51(P<0.05)和0.50(P<0.05),可溶性糖含量的间接通径系数为-0.75(P.<0.05)。在影响2种方法测定桃树抗寒性的生理指标中,脯氨酸含量、可溶性糖含量与含水率都是重要的生理指标。同时,EIS也可以作为快速测定桃树抗寒性的方法。通径分析方法能够充分反映自变量对因变量的影响,同时也可以反映因变量之间的关系,能够应用于研究影响桃树抗寒性与生理指标相关性的分析中。

Abstract:The purpose of this experiment was to find scientific statistic method to analyze physiological indicators of cold resistance of peach trees (Prunus persica L.). The relations among cold resistance and the four physiological indicators, including soluble sugar, proline, starch and water contents were studied by path analysis. Cold resistance was determined by parameters of electrical impedance spectroscopy (EIS) and electrolytic leakage (EL). Shoots of 8 year old peach trees were collected for the experiment from Shibei Village (Heibei Province, China, 37°96′N,115°44′E, altitude of 31m). The results showed that parameter of EIS had a direct relation to proline and soluble sugar contents, with -0.35 and -0.61 (P<0.05) as direct path coefficients, respectively, and indirect relation to water content, with 0.53 (P<0.05) as indirect path coefficient. EL parameter had direct relation to proline and water contents, with -0.51(P<0.05) and 0.50 (P<0.05) as direct path coefficients and indirect relation to soluble sugar content, with -0.75 (P<0.05) as indirect coefficient. The results indicated that proline, soluble sugar and water contents were significant physiological indicators for both EIS and EL methods which played a decisive role in cold resistance. An experiment on path analysis method was carried out, which was purposed to be firstly used to prove that EIS as a fast method was also appropriate to test cold resistance of peach trees. Especially, extracellular resistance (re) was the most significant parameter that can reflect cold resistance of peach trees. The results also indicated that path analysis was a reasonable, scientific statistic method to analyze relations to physiological indicators for cold resistance. The results of this experiment can be applied to study the correlation analysis of cold resistance of peach trees and the physiological indicators, as well as increasing the effectiveness and accuracy of selecting physical indicators.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
