Study on Effects of NaCl Stress on Tuber Germination and Seedling Growth of Cyperus esculentus

YANG Lu-sheng;LI Guo-ping;Wuyi University Teaching Affairs Division;Wuyi University College of Ecology and Resource Engineering;  
Using sand culture method,the effects of different concentration NaCl stress on tuber germination and seedling growth of three chufa lines were investigated. The results showed that the tuber germination rate gradually decreased with the increasing of NaCl concentration. Tubers could not germinate at the treatment of 500 mmol /L NaCl. The chlorophyll content in chufa leaves decreased with the increasing of NaCl stress,while the protein and proline content increased with the increasing of NaCl dosage. These results indicated that tubers germination and seedling growth were significantly inhibited by NaCl stress. It might provide the seferences for the planting and cultivation of Cyperus esculentus in saline-alkali land.
