The results showed S curve for effects of NaCl stress on germination of watermelon seed, the middle point between two inflexions of the curve was at 120mmol/L and could be used as referenced screening concentration to study 'ZQK0395' salt tolerance genetics, the second curve inflexion was at 180mmol/L and could be used as referenced concentration for 'ZQK0395' salt-tolerant germplasm selection.

结果表明，NaCl胁迫对种子发芽的影响呈S型变化曲线，120mmol/L为S型曲线两个拐点中间值，可作为该种质资源耐盐性遗传研究的参考鉴定浓度，180mmol/L为S型曲线的第二个拐点，可作为该种质资源耐盐性参考筛选浓度。

As a native of Litchi chinensis, China is abundant in germplasm resources in the tropical and south sub-tropical zone. In Hainan province, Some big wild litchi trees and batches of wild litchi have been found in the tropical origenate forestry of Bawang, Wuzhi, Jianfeng, Diaoluo, and Jingu Mountains. In addition, there are 4,000hm2 of litchi seedlings scattered on Hainan island. They comprise a huge gene pool of litchis germplasm resources,Which is both bases of seedling selection at present and source of genetic breeding in the future.

中国是荔枝的发源地，种质资源非常丰富，仅海南就有4，000hm~2荔枝实生树，此外，在坝王岭、五指山、尖峰岭、吊罗山和乐东金鼓岭上还有成片的野生荔枝，一起构成了一个巨大的海南荔枝种质资源库，既是我们目前进行实生选种的基础，又是将来杂交育种的源泉。

Although a certain correlation with the morphological classification based mainly on the characteristic of tubercles on the ripe fruit skin,the range of classification by RAPD was more detailed than that of morphological classification.
