Abstract

Abstract:

In this study, two japonica/indica hybrids (JIH) (Yongyou 1540 and Yongyou 4540 with the total growth duration ranged from 169 to 171 days) of Yongyou series, two japonica conventional (JC) varieties (Zhendao 13 and Wuyunjing 30 with the total growth duration ranged from 159 to 160 days), and two indica hybrids (IH) varieties (Liangyoupeijiu and Yangliangyou 6 with the total growth duration ranged from 140 to 141 days) were grown to compare the characteristics and differences of above-ground biomass accumulation after transplanting among three variety types in 2015 and 2016. Grain yield of JIH was averaged 12.4 t hm ^-2 for two years, and 7.8% and 23.3% higher at P < 0.05 than that of JC and IH, respectively. Compared with JI and IH, JIH had lower panicle per m ², filled-grain percentage, and 1000-grain weight, while more spikelets per panicle. JIH also had higher total biomass weight at maturity stage, while lower harvest index. The biomass weight in stem and leaf and their ratio at maturity stage were the highest in JIH and lowest in IH. JIH had the highest panicle weight while IH had the lowest panicle weight, and the opposite trend was observed in the ratio of panicle weight to the total biomass weight at maturity among three variety types. The above-ground biomass accumulation dynamics after transplanting of JIH, JC, and IH were all well fitted by Gompertz equation. The above-ground biomass accumulation rate of different variety types showed a single-peak curve of increasing trend and then a decreasing trend after transplanting. The maximum biomass accumulation rate of JIH, JC, and IH was observed at 61-62, 64-66, and 63-64 days after transplanting, respectively. The maximum biomass accumulation rate of JIH was 17.7% and 17.3% higher than that of JC and IH, respectively. Compared with JC and IH, JIH had higher mean biomass accumulation rate in the early, middle, and late stages; and JIH had lower duration days in the early and middle stages and higher duration days in the late stages. Compared with JC and IH, JIH had higher biomass accumulation in the early, middle, and late stages. In this study, a Gompertz model was established that conformed to the dynamic characteristics of above-ground biomass accumulation after transplanting in different variety types. Compared with JC and IH, JIH had superior biomass accumulation in the early, middle, and late stages; the higher biomass accumulation in the early and middle stages were due to the higher biomass accumulation rate, and higher biomass accumulation in the late stage was due to its higher biomass accumulation period and accumulation rate.
