超级杂交稻两优培九及其亲本生育后期内源激素和营养生理研究
The Endogenous Hormones and Nourishment Physiology Research of the Super Hybrid Rice Liangyoupeijiu and Its Parents after Heading
摘要
Abstract
The leaf chlorophyll , the roots bleeding amount , the content of nutrient elements and hormones in leaves and roots were studied after rice heading with Liangyoupeijiu and its parents as materials.The results showed that:Compared with 9311, the leaf chlorophyll content of Liangyoupeijiu (LYPJ) reduced more quickly after heading , and kept at a lower level , so LYPJ had premature senility characteristic.Except the ABA content in leaves and roots of LYPJ , all other physi-ological traits were lower than those of 9311.Among the LYPJ, 9311 and Peiai 64S, the value of physiological traits of Peiai 64S were the lowest.So it was speculated that the premature senility characteristic of LYPJ maybe inherited from Peiai 64S.The value of all physiological traits of leaf and root of LYPJ and its parents reduced after heading , aerial part and roots aged gradually , which indicated that the above ground part and under ground part correlated each other closely , but there was not absolute correlation between them judged from the experimental data .关键词
