Abstract
To study the response of sugarcane hybrids under nutrient stress, four different varieties were used as materials, including one BC3 from hybrids of sugarcane and Erianthus arundtnaceus, one BC1 from hybrids of sugarcane and Saccharum spontaneum and two cultivated varieties. The plant growth, nutrient concentration and nutrient accumulation amount were evaluated under low nitrogen stress, low phosphorus stress or low potassium stress. The results revealed that plant height, diameter, dry weight of shoot and dry weight of root of four varieties all decreased under low nutrient stress. The decrease in these parameters was lower in YC10-29 under low potassium stress and YC06-92 under low phosphorus stress than those in the other two cultivated varieties. Under low nutrient stress, the ratio between root and shoot increased and the diameter of root under low potassium or phosphorus stress decreased, which lead to the increase of total root length, especially the total root length of YC06-92 under low potassium stress, which was 2.67 times higher than that of CK. There were significantly interactions among different nutrients under low nutrient stress. Under low potassium stress, the concentration of phosphorus in plant increased,while the concentration of potassium and phosphorus increased under low nitrogen stress. In addition, the potassium and phosphorus accumulation amount in plant under low nitrogen stress was higher than those under low potassium and phosphorus,especially in ROC22. Therefore, among four varieties, YC10-29 showed higher tolerance to low potassium stress, YC06-92 possessed excellently tolerance to low phosphorus stress and ROC22 showed higher tolerance to low nitrogen.
