Tolerance of Taraxacum officinale to Waterlogging
摘要
Abstract
Taraxacum officinale is widely distributed in China.It is highly valued as a medicinal and food material with broad application prospects.However,its waterlogging tolerance has not been reported.Using the dandelions collected in Jingzhou city and at XiJiaChi Garden,Xiangyang city for the experiment,changes in the physiological and morphological indicators of the plants under artificial flooding condition were studied.The results showed that (1) the MDA and free proline contents and CAT activity were significantly higher in Jingzhou than XiJiaChi dandelions,while the chlorophyll content lower than Xijiachi,which suggested that the variety from XiJiaChi were more resistant to waterlogging than that from Jingzhou;and,(2) under 30 ds of waterlogging,the dandelions showed higher scores on the external morphological indices,some with significant differences,as compared to those grown under normal conditions.It appeared that Xijiachi dandelions was highly tolerant to waterlogging and could be adequately planted in Jianghan Plain and other regions with similar geological and environmental conditions.关键词
