摘要:

【目的】分析不同生态环境下葡萄光合特性变化,研究2个葡萄品种在不同生态条件下光合特性的差异,分析不同主栽葡萄品种对生态环境的适应性。【方法】在乌鲁木齐市安宁渠镇和吐鲁番市鄯善县2个生态环境条件下进行试验,以无核白鸡心和无核白2个葡萄品种为材料,采用LI-6400和FMS-2测定其光合指标和荧光参数,分析不同生态环境条件下温度和光照差异对2个葡萄品种光合特性的影响。【结果】鄯善葡萄架下最高温度持续时间和光照时间均高于乌鲁木齐,鄯善最高温度为43℃,乌鲁木齐最高温度仅有38℃,日最高温度超出35℃的天数分别为86和20 d。鄯善PAR值高于乌鲁木齐,鄯善最高值为1 975.5 μmol/(m2·s)。2个葡萄品种叶片净光合速率日变化曲线均呈双峰趋势,鄯善高于乌鲁木齐,10:00时无核白鸡心葡萄净光合速率日变化在鄯善为41.8 μmol/(m2·s),显著高于乌鲁木齐的39.4 μmol/(m2·s)。2个葡萄品种表观量子效率、暗呼吸速率、ΦPSⅡqPNPQ等值均表现为在鄯善高于乌鲁木齐,电子传递速率在乌鲁木齐高于鄯善。【结论】无核白鸡心葡萄在鄯善环境条件下对光能的利用能力优于乌鲁木齐,鄯善的净光合速率高于乌鲁木齐,该葡萄品种对鄯善环境逐渐适应;鄯善环境条件下实际光化学效率、qPNPQ值均大于乌鲁木齐,电子传递速率在乌鲁木齐值更高。无核白葡萄对光能的利用率在乌鲁木齐环境条件下优于鄯善,相较于无核白鸡心葡萄该品种对鄯善环境适应能力较差;鄯善实际光化学效率、qPNPQ、电子传递速率等值均高于乌鲁木齐。

Abstract:

【Objective】 To study the differences of photosynthetic characteristics of two grape varieties through the analysis of the changes of grape photosynthetic characteristics under different ecological environments and explore the effects of ecological conditions on grape photosynthetic characteristics.【Methods】 In this project, experiments were carried out under two ecological environment conditions: Urumqi region (Anningqu Town, Urumqi) and Shanshan region (Shanshan County, Turpan).Two grape varieties Centennial Seedless and WuHebai were taken as the experimental objects, their photosynthetic indexes and fluorescence parameters were measured by Li-6400 and FMS-2, and the effects of temperature and light differences on the photosynthetic characteristics of the two grape varieties under different ecological environment conditions were analyzed.【Results】 The results showed that the maximum temperature duration and light time in Shanshan under the grape shelf were higher than those in Urumqi.The maximum temperature of high-temperature environment there was 43℃, the maximum temperature of suitable temperature environment was only 38℃, and the days when the daily maximum temperature exceeded 35℃ were 86 d and 20 d respectively.The PAR value in Shanshan region was higher than that in suitable temperature environment, and the highest value in Shanshan was 1,975.5 μmol/(m2·s).The diurnal variation curve of leaf net photosynthetic rate of the two grape varieties showed a bimodal trend.The overall trend was that the high-temperature environment was higher than the suitable temperature environment.At 10:00 a.m., the diurnal variation of net photosynthetic rate of Centennial Seedless grape was 41.8 μmol/(m2·s) in the high-temperature environment, which was significantly higher than 39.4 μmol/(m2·s) in the suitable temperature environment.In terms of apparent quantum efficiency, dark respiration rate, the equivalence of ΦPSⅡ, qP and NPQ of the two varieties, they were higher in Shanshang, but the electron transfer rate in the Urumqi region was higher than that in Shanshan.【Conclusion】 The utilization ability of light energy of Centennial seedless under Shanshan region is better than that under suitable temperature environment, and the net photosynthetic rate under Shanshan region is higher than that under suitable temperature environment, which proves that the grape variety gradually adapts to Shanshan region; the utilization rate of light energy of Thompson seedless is better than that of Shanshan region under suitable temperature environment, and the adaptability of this variety to Shanshan region is poor.
