- 摘要:
- 以九年生‘新郁’和‘红提’2个红色葡萄品种为试验材料，采用LI-6400和FMS-2对光合指标和荧光参数进行测定，分析不同生态环境下葡萄光合特性变化，通过对不同生态环境条件下2个红〖JP+2〗色葡萄品种光合特性差异的研究，阐明2个红色葡萄品种对生态环境的适应性，以期为大田生产提供参考依据。结果表明：葡萄棚架下，鄯善年最高温度及高温持续时间和光照时间均高于乌鲁木齐，鄯善地区最高温度可达42.5 ℃，乌鲁木齐地区最高温度仅38 ℃，日最高温度高于35 ℃的天数分别为86 d和20 d。乌鲁木齐地区PAR值高于鄯善地区，乌鲁木齐和鄯善最高值分别为1 822 μmol·m-2·s-1和1 975.5 μmol·m-2·s-1。2个红色葡萄品种在不同生态环境条件下，叶片净光合速率日变化均表现为双峰曲线，鄯善地区总体趋势高于乌鲁木齐地区。10:00时，‘红提’葡萄净光合速率日变化在鄯善地区为23.75 μmol·m-2·s-1，显著高于乌鲁木齐地区的13.55 μmol·m-2·s-1；‘新郁’葡萄在鄯善地区的值为16.6 μmol·m-2·s-1，低于乌鲁木齐地区。2个红色葡萄品种在鄯善地区的光饱和点、暗呼吸速率、量子效率、ΦPSⅡ、ETR等值均高于乌鲁木齐地区，Pmax、qP和NPQ值在乌鲁木齐地区优于鄯善地区。
- Abstract:
- Two 9-year-old red grape varieties ‘Xinyu’ and ‘Hongti’ were used as experimental materials，and the photosynthetic indexes and fluorescence parameters were measured by LI-6400 and FMS-2，and the changes of photosynthetic characteristics of grapes in different ecological environments were analyzed.Through the study on the difference of photosynthetic characteristics of two red grape varieties under different ecological environment conditions，the adaptability of two red grape varieties to the ecological environment was clarified,in order to provide reference for field production.The results showed that under the grape trellis，the annual maximum temperature，high temperature duration and light time in Shanshan were higher than those in Urumqi.The maximum temperature in Shanshan was 42.5 ℃，the maximum temperature in Urumqi was only 38 ℃，and the days when the daily maximum temperature was higher than 35 ℃ were 86 days and 20 days respectively.The PAR value in Urumqi was higher than that in Shanshan.The highest values in Urumqi and Shanshan were 1 822 μmol·m-2·s-1 and 1 975.5 μmol·m-2·s-1 respectively.Under different ecological environment conditions，the diurnal variation of leaf net photosynthetic rate of the two red grape varieties showed a bimodal curve，and the overall trend in Shanshan area was higher than that in Urumqi area.At 10:00 am，the diurnal variation of net photosynthetic rate of ‘Hongti’ grape was 23.75 μmol·m-2·s-1 in Shanshan area，significantly higher than 13.55 μmol·m-2·s-1 in Urumqi.The value of ‘Xinyu’ grape in Shanshan area was 16.6 μmol·m-2·s-1，lower than that in Urumqi.Light saturation point，dark respiration rate，quantum efficiency,the equivalent values of ΦPSⅡ and ETR were higher than those in Urumqi，and the values of Pmax，qP and NPQ in Urumqi were better than those in Shanshan.
