Abstract

Abstract:

Plant growth regulators play a crucial role in the growth, development, high yield and high quality of rice. This study aimed to investigate the effects of two growth regulators, Aizengduo and Jinduoshou, on rice yield and quality. The experiment was conducted with two high-yielding and quality rice varieties, ‘Nanjing 5718’ (approved by Jiangsu Province as 20210047, a japonica rice variety) and ‘Huiliangyou 858’ (approved by Anhui Province as 2016023, an indica rice variety). Four treatments were set up, including Aizengduo, Jinduoshou 1, Jinduoshou 2 and a blank control. The study focused on the impact of Aizengduo and Jinduoshou on rice yield and its components, as well as rice quality, to clarify the effects of these regulators on enhancing rice yield and quality. The results showed that applying Aizengduo promoted tillering, spikelet differentiation, and grain filling, significantly increasing the yield of japonica rice. The application of Jinduoshou 1 and Jinduoshou 2 improved the number of effective panicles and spike differentiation and flowering in indica rice, with Jinduoshou 1 having a significant effect on increasing indica rice yield. For ‘Huiliangyou 858’, the head rice rate was highest under the Jinduoshou 1 treatment. Significant differences in head rice rate were observed among the four treatments for ‘Nanjing 5718’. In ‘Huiliangyou 858’, the final viscosity was highest with Aizengduo, and the appearance, palatability, and taste values were highest with Jinduoshou 1. For ‘Nanjing 5718’, the highest final viscosity was observed with Jinduoshou 1, the highest breakdown value with Jinduoshou 2, and the lowest setback value with Jinduoshou 2. Aizengduo treatment resulted in the highest scores for appearance, viscosity, balance, taste value, and the lowest hardness. The amylose content was highest in the blank control for ‘Huiliangyou 858’ and lowest in Jinduoshou 2 for ‘Nanjing 5718’. The study provides theoretical references for innovating high-yield and quality rice cultivation techniques and improving rice production efficiency.
