Abstract: 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.
