摘要

以华北型黄瓜品种津春4号和欧洲温室型黄瓜品种戴多星为试材,采用遮光处理获得不同徒长程度的黄瓜幼苗,研究了幼苗徒长程度对黄瓜植株生长发育及果实产量和品质的影响.结果表明:在遮光条件下,黄瓜幼苗发生不同程度徒长,定植后对植株生长发育和果实产量品质影响显著.徒长苗株高和下胚轴长显著高于对照苗,茎粗、叶面积、干质量、干物质含量以及根冠比和壮苗指数均显著低于对照苗.定植后,植株株高、茎粗、叶片数和叶面积仍与对照苗差异显著.与对照苗相比,徒长苗初花期延后,第1雌花节位升高,平均单株结果数、单果质量、单株产量和前期产量均显著下降,果实可溶性同形物、可溶性糖、可溶性蛋白和VC含量也显著降低.说明黄瓜徒长苗定植后对植株生长发育和果实产量与品质有显著的不利影响.%Using 2 different ecotypes of cucumber ( Cucumis sativus L. ) variety ‘ Jinchun No.4’ and ‘ Daiduoxing’ as materials to obtain a couple of cucumber seedlings with different leggy extent by shading,the effects of seedlings leggy extent on cucumber plant growth, fruit yield and quality were studied. The results showed that different degrees of cucumber seedlings leggy growth occurred under shading conditions, and planting had significant impact on plant growth, fruit yield and quality. The plant height and hypocotyl length of leggy seedlings were significantly higher than that of the control, but the stem diameter, leaf area, dry weight, dry matter content, root/shoot ratio and seedling index all displayed opposite changing trend. After planting, the plant height, stem diameter, leaf number and leaf area of leggy seedlings were significantly differed from those of the control seedlings. Compared with the control, the leggy seedlings delayed its early blooming period; the node of its first female flower was higher; while the average pod number per plant, fruit weight, and early yield per plant and per unit area were all significantly decreased; its fruit soluble solids, soluble sugar, soluble protein and VC contents were also significantly reduced. This suggested that after planting cucumber leggy seedlings had significant negative effects on plant growth, fruit yield and quality.
