[Method] The effects of seven foliar fertilizer and growth regulators on the major economic traits of Jinhua Large and White Peach were studied. [Result] After timely spraying of S-ABA and Fushizhuang in young fruit stage,the major economic traits of Large and White Peach including fruit weight and soluble solids content were significantly higher than that of the control,and significantly better than other treatments. In addition,Huoqing spraying treatment could obviously improve the quality of Large and White Peach. [Conclusion] Shifuzhuang,S-ABA and Huoqing spraying could significantly improve the quality of Jinhua Large and White Peach,which were suitable to be disseminated and applied in production.展开更多

The results showed that "Chuanzhongdao" White Peach had no obvious differences from microsporcyte meiosis, tetrads to mononuclear spherical microspores from male fertility variety. Microspores began to abort at its further development, that is,the nucleus disappeared, the cytoplasm reduced and became light staining , and the empty pollen grains were produced at last. The tapetum, endothecium and middle layer of anthers developed abnormally at later stage, which expressed that the tapetum cells did not disintegrate completely; the middle layer cells enlarged; and the endothecium cells lengthened radially early, but there were no fibrous thickenings in the endothecium cells.
