摘要
甜瓜是葫芦科甜瓜属一年生蔓性植物，有厚皮甜瓜和薄皮甜瓜两大生态类型。用不同浓度的NAA处理甜瓜种子，研究其对发芽率、幼苗生长情况、叶绿素含量及根系活力等指标的影响，从中筛选出适合甜瓜种子萌发和幼苗生长的NAA较佳处理浓度，以期为提高甜瓜种子发芽率、发芽整齐度、如何节约种子和缩短育苗周期提供技术参考。结果表明，较低浓度的NAA（10^-10-10^-6mgg/L）可以增加甜瓜种子的发芽率、根长、侧根数、叶绿素含量和根系活力。
Two ecological types are annual Vine plants, Melon and Muskmelon also known as cantaloup melon, Cucurbitaceae melon. Different concentrations of NAA direct to cantaloup melon seeds, and to study the germination rate, the growth of seedlings, chlorophyll content and root activity indicators, screened from the NAA for cantaloup melon seed the optimum concentration of germination and growth, in order to improve the germination rate of seeds of cantaloup melon, germinating, how to save seed and to shorten the breeding cycle of the Technical Reference. The results showed that low concentrations of NAA （ 10^-10-10^-6 mg/L）can increase the germination rate of cantaloup melon, root length, lateral root number, chlorophyll content and root activity.
