摘要
水培试验表明 ,在相同的栽培条件下新几内亚凤仙 4个品种的根系活力、叶片硝酸还原酶活性及根系SOD、POD等保护酶活性明显不同。这些生理特性的大小均为品种Ⅱ >品种Ⅳ >品种Ⅲ >品种Ⅰ ,说明不同品种对水培的适应能力各不相同 ,其中品种Ⅱ的适应性最强 。
The root vigor and the activities of the NR, SOD and POD of the four different Impatiens hawkeri varieties were studied under solution culture. The results showed that the adaptability of the four varieties to solution culture was much different. Under the same growing conditions, the activities of these physiological characteristics are the varietyⅡ> Ⅳ >Ⅲ>Ⅰ. The adaptability of varietyⅡis the best among the four varieties.
