Abstract: In order to obtain the application feasibility of ramie in hydroponics under low temperature stress, in this study, the tender shoots of 10 ramie germplasms are cultivated in hydroponics under plastic greenhouse which had no devices of temperature control, humidity control or heating. We first studied the growth percentage of adventitious root primordia and adventitious roots of ramie germplasm stems and survival rate of hydroponics ramie. The results showed that the stems of 10 ramie germplasms were all long out of adventitious root primordia in hydroponics after 7 days. The growth rates of adventitious root primordia of 3 ramie germplasms were more than 70% , of which‘Dongkou Qing Pi Ma’was 100% . Adventitious roots had extremely and significantly positive correlation with adventitious root primordia. The correlation coefficient was 0.912. There were six ramie germplasms whose adventitious roots growth rates were more than 60.00%, and the best germplasm was‘Yichun Tong Pi Qing Ma’. After winter, hydroponic seedling survival rates of 10 ramie germplasms had significantly positive correlation with adventitious root primordia and adventitious root. The correlation coefficients were 0.845 and 0.811, respectively. Hydroponic seedlings of 10 ramie germplasms grew differently. The survival rates of‘Yichun Tong Pi Qing Ma’,‘Dongkou Qing Pi Ma’and‘Mazui Bai Ma’were better than that of others. The rates were 75.56%, 68.89% and 60.00%, respectively.
