The effect of low temperature on the germplasm preservation with the plantlets of Eriobotrya japonica Lindl. was investigated. The results showed that in normal temperature (25℃) the plantlets grew fast, their preservation time was short and all died after 10 month. In low temperature, the plantlets grew slowly, their preservation time was longer than that in normal temperature. At 11℃ and 15℃, death rates of plantlets of two cultivars 'Jiefangzhong' and 'Zaozhong No. 6' were only 20%, 25% and 15%, 20% resp...
