关键词:超级稻; 籼稻; 粳稻; 根系; 形态特征; 生理特征 Difference of Root Morphological and Several Physiological Characteristics betweenIndica andJaponica Super Rice Varieties GONG Jin-Long, XING Zhi-Peng, HU Ya-Jie, ZHANG Hong-Cheng*, DAI Qi-Gen, HUO Zhong-Yang, XU Ke, WEI Hai-Yan, GAO Hui, GUO Bao-Wei Innovation Center of Rice Cultivation Technology in the Yangtze Valley, Ministry of Agriculture / Key Laboratory of Crop Genetics and Physiology of Jiangsu Province, Yangzhou University, Yangzhou 225009, China Fund: AbstractThe objective of this study was to reveal the difference of dry matter accumulation and its distribution, and the main morphological and physiological characteristics in roots betweenindica andjaponica super rice, and their relationship with yield formation. A field experiment was conducted using two main representative super hybridindica combinations and two conventionaljaponica super rice varieties in wheat-rice double cropping regions. Dry weight of root, total root length, root number, root volume, root absorbing area, root germination ability and root bleeding intensity after heading for both single stem and population, root-shoot ratio, single root length, root diameter, root density, root bleeding per spikelet, root distribution in the soil at heading and yield components were analyzed systematically. Results showed as follows: (1) For the whole growth duration, root-shoot ratio, single root length, root germinating number, root germinating volume, root germinating dry weight, root bleeding per spikelet, number of panicles, total spikelets, seed-setting rate, and grain yield ofjaponica rice were higher than those ofindica rice, while root diameter, spikelets per panicle and 1000-grain weight followed an opposite tendency, with root-shoot ratio, single root length, root bleeding per spikelet, number of panicles, spikelets per panicle, seed-setting rate and grain yield being a significantly different. (2) Before heading, dry weight of root, total root length, root number, root volume and total absorbing surface area of root per stem and root density ofjaponica rice were lower than those ofindica rice, though not significantly, and higher than those ofindica rice significantly at maturity. (3) Before jointing, active absorbing surface area per stem and ratio of active absorbing surface area to total absorbing surface area injaponica rice were less than those inindica rice significantly, which showed an opposite trend after jointing. (4) Population indicators of morphological and physiological characteristics ofjaponicarice except for population root dry weight at jointing and root number of population at jointing and heading were higher than those ofindica rice significantly. (5) Root bleeding intensity during 0-35 d after heading was higher injaponica rice than inindica rice significantly whether it was based on a single stem or population. (6) Ratio of root dry weight in the 0-10 cm layer to total root dry weight was lower injaponica rice than inindica rice significantly, with an opposite trend for the >10 cm layer, which indicated the deep-rooted characteristic ofjaponica rice can strengthen its resistance to lodging and premature senescence. Compared with super hybridindica rice, root growth advantages of conventionaljaponica super rice after heading were increased, especially for population growth advantages, and all the root morphological and physiological characteristics indicators ofjaponica rice at maturity were better than those ofindica rice, which is the important cause and assurance for high-yielding formation ofjaponica rice.

4 结论与超级杂交籼稻相比, 常规粳型超级稻抽穗后根系生长优势, 特别是群体生长优势不断加大, 成熟期所有根系形态生理指标均较优, 这些是粳稻保持较高矿质营养元素吸收速度及高产形成的重要保障。粳稻抽穗期群体根系干重大且扎根深, 进一步强化植株抗倒防早衰能力。 The authors have declared that no competing interests exist. 作者已声明无竞争性利益关系。The authors have declared that no competing interests exist.
