Abstract:

This study was conducted to clarify the characteristics for occurrence of rice tillers, its dominant leaf positions, and panicle formation under salinity stress, and to provide a basis for the rational utilization and regulation of rice tillers for high-yield cultivation methods in tidal flat area. Conventional japonica rice Nanjing 9108 was used with three salinity treatments, namely, Control (CK, 0 salt concentration), Medium-salinity stress (MS, 0.15% salt concentration), and high-salinity stress (HS, 0.3% salt concentration) to compare the tillering and panicle formation characteristics and its contribution to population yield under salinity stress. As a result, the average yields (t hm-2) of CK, MS, and HS were 9.7, 7.4, and 4.2 across two years, respectively; the number of panicles, spikelets per panicle, percentage of filled grains, and 1000-grain weight in MS and HS treatments were significantly lower than those in CK. Compared with CK, the number of tillers at jointing, heading, and maturity and percentage of productive tillers in MS and HS treatments were decreased. For CK, the primary tillers emerged from the 3rd leaf to 7th leaf on the main stem, with higher tiller emerging rate and more panicles from the 4th leaf to 6th leaf among them, and secondary tillers mainly emerged and earbeared from 1/4 and 1/5 tiller position; as for MS and HS, tillers are mainly primary ones emerging from the 4th to 6th leaf as the dominant position for the tiller occurrence and earbearing. The mean value of panicle length, total grains, grain density, and number of grains and its total grains on the primary and secondary branches in MS and HS treatments were both lower than those in CK. Our results suggest that, salinity stress caused lower number of panicles per plant, inferior growth of individuals and populations, smaller panicle types, and finally lower grain yield.

Key words: salinity stress, rice, tillering characteristics, population productivity
