- Abstract
【Objective】 To study the effects of shade and light on photosynthetic characteristics, yield and quality of muskmelon with a purpose of exploring the physiological mechanism of shade and light affecting the fruit.【Method】 Based on three local melon varieties in Xinjiang, the experiment was carried out in 2019 at the comprehensive experimental site of Xinjiang Academy of Agricultural Sciences (87°28′E, 45°56′N) at No.1 Xiaokang Road, Anning District, Urumqi City, Xinjiang.【Result】 Compared to normal light, the shading weak light resulted in a rapid decrease in chlorophyll SPAD value, stomatal conductance (Gs), net photosynthetic rate (Pn) and transpiration rate (Tr) in muskmelon leaves, an increase in intercellular CO2 concentration (Ci), and a decrease in soluble solids, soluble sugars, soluble protein content, refractive sugar and vitamin C in melon pulp. The change range of Kalakusai was smaller than that of Bixiekeqin and Qiligan.【Conclusion】 The adaptability of different ecotypes of muskmelon to shade and low light environment is different. Under the condition of mild and severe shading, the photosynthetic performance of muskmelon leaves decrease, the accumulation and output of photosynthetic products are blocked, and the final yield and quality of muskmelon decrease significantly with the deepening of shading (P<0.05).
