摘要 通过对不同品种的西瓜(特大新红宝和极早地雷)施以不同浓度的亚硒酸钠(Na2SeO3)以测定西瓜幼苗的株高、可溶性蛋白质和可溶性多糖的含量及根系活力,研究硒对西瓜幼苗生长发育的影响。结果表明:在相同条件下,Na2SeO3对极早地雷的影响较特大新红宝显著,但影响的趋势基本一致,两者的各方面指标均随Na2SeO3的浓度增加而增加,当浓度达到100 mg/L时株高达到最大值,其他均在150 mg/L时达最大值,而且各指标均在达最大值后呈下降趋势。 Different concentration of solutions which contain selenium were fertilized on two different species of watermelon. It is to study the influence of Se on the growth of watermelon by measuring the watermelon young sprout high, contents of dissoluble protein and sugar. The study showed that in the same condition, the influence of Na2SeO3 was more evidence on Jizaodilei than Tedaxinhonhbao, but similar in the direction. All the index of both were increased by the increasing of the concentration of solutions. The sprout high reached a maximum at the concentration of 100 mg/L, and other index reached the maximum at the concentration of 150 mg/L,and all of them showed a decreasing direction after getting to the maximum.
