Abstract:In order to screen out optimal scented rice materials resistant to low phosphorus, six group of P mass concentration(0.00, 0.25, 0.50, 2.00, 8.00 and 31.00 mg/L) nutrient solution under natural conditions were designed to treat four scented rice materials(Lyujinxiang, Huaxiang, Meixiangzhan 2, Haixiangzhan) at seedling stage. The phosphorus accumulation characteristics and chlorophyll fluorescence parameters were analyzed. The results showed that without P(P0, P mass concentration was 0.00 mg/L) at 35 d, Lyujinxiang was the highest in the phosphorus accumulation(1.45 mg/bottle), Haixiangzhan was the lowest(0.88 mg/bottle). For chlorophyll fluorescence parameters, Haixiangzhan was affected by low phosphorus stress in ΦPSII and ETR with the affection extent coefficient 0.08 and 9.03 respectively, Huaxiang was affected at qP with the affection extent coefficient 0.15 and Meixiangzhan 2 was greatly affected at qN with the affection extent coefficient 0.14. Meanwhile, phosphorus accumulation was significantly positively related to SPAD values, ΦPSII, qP, and ETR. By comprehensive evaluations, the low phosphorus resistance of the four scented materials from strong to weak was Lyujinxiang, Huaxiang, Meixiangzhan 2, Haixiangzhan under low phosphorus stress.
