摘要: 研究了不同浓度5-氨基乙酰丙酸(ALA)溶液(0、5、10、20、40、70 mg/L)浸种对甜瓜幼苗生长及生理特性的影响。结果表明:与CK相比,ALA浸种处理促进了甜瓜幼苗生长,随着ALA浓度的提高,甜瓜幼苗的株高、茎粗、植株鲜重和干重、壮苗指数均呈先增加后降低的趋势,20 mg/L处理最高。ALA浸种处理提高了甜瓜幼苗叶片的可溶性糖、可溶性蛋白含量,并降低了丙二醛含量,以20 mg/L处理效果最好。因此ALA浸种处理能促进甜瓜幼苗生长,提高壮苗指数,并显著增强抗逆性,20 mg/L为最佳浓度。
Abstract: Effects of seed soaking with different concentrations of 5-aminolevulinic acid (0, 5, 10, 20, 40, 70 mg/L) on the growth and physiology of melon seedlings were studied. The results showed that, compared with the contrast (CK, 0 mg/L), seed soaking with 5-aminolevulinic acid promoted the growth of melon. With the enhancement of 5-aminolevulinic acid concentration, the plant height, stem diameter, fresh and dry weight, seedling strength index tend to increase first and then decrease, and the treatment of 20 mg/L is the highest. Seed soaking with 5-aminolevulinic acid treatments increased the content of soluble sugar and soluble protein, and decreased the malondialde-hyde content in melon seedling leaves, among them the treatment of 20 mg/L being the best. Thus seed soaking with 5-aminolevulinic acid could increase the growth and seedling strength index of melon, also promote its stress resistance, with the best concentration of 20 mg/L.
