| 摘 要： | 【目的】探讨3种光质补光对巨峰葡萄春果生长发育及光合特性的影响，为完善广西巨峰葡萄春果栽培管理技术提供理论依据。【方法】以5年生设施栽培巨峰葡萄为试验材料，在新梢展叶期至果实成熟期，应用白、红、蓝3种光质进行夜间非连续光照6 h（03:00—06:00和18:00—21:00）处理，以自然光照为对照（CK），研究不同补光处理对巨峰葡萄春果新梢生长、叶片叶绿素含量、光合生理及果实生理生化等指标的影响。【结果】在3种不同光质补光条件下，巨峰葡萄春果新梢基部粗度、1~10节总长度、叶长、叶宽、叶柄长和叶厚均高于CK；其中蓝光6 h处理的新梢基部粗度和1~10节总长度增量最大，分别较CK显著增加12.80%和27.00%（P<0.05，下同）；白光6 h处理的叶长、叶柄长、叶厚和叶片长宽比等指标表现最优，分别较CK提高11.78%、55.90%、12.90%和1.85%；红光6 h处理的叶宽表现最大，较CK显著提高15.06%；相较于CK，在巨峰葡萄春果各生长期夜间补充白光6 h和红光6 h均能提高其叶片叶绿素含量；不同光质补光处理的巨峰葡萄春果叶片净光合速率、气孔导度和蒸腾速率及果实单粒重、横径和可溶性固形物含量均呈现不同程度升高，而叶片胞间CO2浓度和果实可滴定酸含量呈现不同程度降低。【结论】在巨峰葡萄春果栽培过程中，夜间补充白光6 h和红光6 h能在一定程度上弥补光照的不足。因此，可通过人工补光调节葡萄的生长发育状况，提高果实品质。

| Abstract: | 【Objective】 The effects of three kinds of light quality supplemental on the growth and photosynthetic characteristics of spring berry of Kyoho grape were studied and provided theoretical basis for improving the cultivation and management techniques of spring berry of Kyoho grape in Guangxi.【Method】 Five-year Kyoho grape in facilities cultivation was selected as the research object and exposed to three different kinds of discontinuous illumination treatments at night, including white, red and blue lights for 6 h(03:00-06:00, 18:00-21:00), natural light was taken as control(CK). The treatment was prolonged from the new shoots expansion period until harvest. The effects of different supplemental light treatments on shoot growth, leaf chlorophyll content, photosynthetic physiology and fruit physiology and biochemistry indexes of spring berry of Kyoho grape were studied.【Result】 Under three different light quality conditions, the basal diameter, length of shoot from the 1st to 10th node, leaf length, leafwidth, petiole length and leaf thickness of spring berry of Kyoho grape was higher than the CK. The basal diameter and the length of shoot from the 1st to 10th node had the largest growth increment and significantly increased by 12.80% and 27.00% than CK under blue light treatment for 6 h(P<0.05, the same below). The leaf length, petiole length, leaf thickness and ratio of leaf length to width of 6 h white light treatment were the best, which were 11.78%, 55.90%, 12.90% and 1.85% higher than CK, respectively. The leaf width had the largest growth increment and significantly increased by 15.06% than CK under red light treatment for 6 h. Compared with CK, supplement of white light for 6 h and red light for 6 h at night could increase the chlorophyll content of Kyoho grape leaves at different growth stages. The net photosynthetic rate, stomatal conductance, transpiration rate, single berry weight, transverse diameter and soluble solids of Kyoho grape spring berry increased in different degrees under different light qualities and light supplement treatments, while the intercellular CO2 concentration of the leaf and titratable acid content of fruit decreased in different degrees.【Conclusion】 The results show that 6 h supplemental red light and white light treatments can compensate for the lack of light in the spring Kyoho grape cultivation. The growth and development of grapes can be adjusted through artificial light supplement to improve the berry quality. |
