摘要:

以‘阳光玫瑰’葡萄为试材,记录试验果园葡萄夏果生长季光照强度与时数,并分析其与气象部门提供的日照时数的差异,测定叶片不同物候期的光饱和点、光补偿点,分析光照时数和强度对净光合速率和产量的影响。结果表明,气象站观测以直射光为主记录的日照时数明显低于果园记录的光照时数,并且未完全包含葡萄可利用光照强度的日照时数。不同物候期的‘阳光玫瑰’葡萄叶片光补偿点范围为22.43 ~ 49.77 μmol · m-2 · s-1,叶片光饱和点范围为1 108.07 ~ 1 303.01 μmol · m-2 · s-1。葡萄产量与光补偿点以上的光照时数的关系更为密切,在光补偿点以上的光照时数1 524.1 h(2018年)和1 579.8 h(2019年)下,产量分别为13 701.9 和17 774.9 kg · hm-2,且平均可溶性固形物大于17 Brix°。建议在葡萄生产和品质评价中,在掌握品种叶片光饱和点和光补偿点的基础上,综合考虑葡萄生长发育周期中光照时数和光照强度的影响。

Abstract:

To explore the relationship between duration or intensity of sunlight and the yield of grape harvest. The light durations and intensities recorded in the summer fruit growing season with those provided by meteorological department were analyzed. Light saturation point and light compensation point of leaves of‘Shine-Muscat’grape during different phonological stages,and the effects of light duration and intensity on net photosynthetic rate and yield of summer fruit of‘Shine-Muscat’grape were analyzed. The results showed that the total light duration recorded by the meteorological station based on direct sunlight was significantly lower than that recorded in the vineyard and did not fully include the light duration corresponding to the light intensity that is available for grape production. Light intensity significantly affected the net photosynthetic rate of‘Shine-Muscat’grape leaves. The light compensation point and light saturation point of leaves of‘Shine-Muscat’grape varied in different developmental stages. The light compensation point of leaves ranged from 22.43 to 49.77 μmol · m-2 · s-1,and the light saturation point of leaves ranged from 1 108.07 to 1 303.01 μmol · m-2 · s-1. The formation of grape yield is more closely related to the sunshine hours above the light intensity at the light compensation point,and under the light hours above the light compensation point of 1 524.1 h(2018)and 1 579.8 h(2019),the yield of grapes was 13 701.9 and 17 774.9 kg · hm-2 respectively,and the average soluble solids was more than 17 Brix°. Therefore,suggested that in grape production and quality evaluation,the effects of light hours and light intensity in grape growth and development cycle should be comprehensively considered based on the light saturation point and light compensation point of variety leaves.
