Abstract

Abstract:

To investigate the effect of salinity stress on grain-filling and yield of rice, the conventional japonica rice Nanjing 9108 and Huaidao 5 which were widely planted in saline alkali soil of Jiangsu province were used as the experimental materials. The treatments including the control (CK, 0 salt concentration), medium-salinity (medium-salinity, MS, 0.15% salt concentration), and high salt (high salinity, 0.3% salt concentration) were set. The results showed that, compared with the CK: (1) MS and HS both significantly reduced rice grain yield by 26.3% and 57.7% (average of the two cultivars), respectively. The number of panicles, spikelets per panicle, filled-grain percentage, and 1000-grain weight were all significantly decreased under salinity stress. (2) Salinity stress significantly reduced rice panicle length, the number of superior and inferior grains per panicle, filled-grain percentage, and 1000-grain weight. The decreases in filled-grain percentage and 1000-grain weight of superior grains per panicle under salinity stress were lower than those of inferior grains. (3) Salinity stress significantly reduced the dry matter weight of plants at heading and maturity stages, and the dry matter accumulation from heading to maturity, while increased the harvest index. The net photosynthetic rate and SPAD value at 15 and 30 days after heading of rice leaves under salinity stress were significantly lower than CK. (4) Salinity stress reduced the maximum and mean grain-filling rates of grains during grain-filling period, while the time to achieve the maximum grain-filling rate and effective grain-filling duration of grains increased. Salinity stress increased the days at the first, middle, and late stages during grain-filling period for superior and inferior grains, while the mean grain-filling rate and grain filling amount significantly decreased at the first, middle, and late stages during grain-filling period. The decrease in grain filling amount of superior grains at the first, middle, and late stages during grain-filling period was lower than that of inferior grains. (5) Salinity stress significantly decreased activities of ADP-glucose pyrophosphorylase (AGPase), starch synthases (SSS), granule-bound starch synthase (GBSS), and starch branching enzymes (SBE), and the decrease was greater in inferior grains than superior grains. In conclusion, the grain-filling days for superior and inferior grains increased under salinity stress, but the decrease in grain filling rate and activities of key enzymes involved in starch synthesis was greater, resulting in a significant deterioration in grain filling traits and a significant decrease in grain weight and yield. The inhibitory effects of salinity stress on grain-filling rate and grain filling amount of inferior grains were higher than those of superior grains.

Key words: salinity stress, rice, grain-filling, grain yield
