摘　　要：‘保佳俊’是河北农业大学选出的白肉桃新品系,其果实外观和口感都表现出较好的特征,综合经济性状优良。为全面了解其生长结果习性,本研究以与‘保佳俊’成熟期相近的‘大久保’为对照品种,对比研究了‘保佳俊’的物候期、花芽、花器官和果实品质等植物学特性。结果表明:‘保佳俊’新梢生长量小,各类结果枝均易形成花芽;果实发育期114 d;果实个大,粘核,可溶性固形物含量高,固酸比高,硬度大,风味甜,是一个品质优良的新品系。‘Baojiajun＇ is a new white-fleshed peach strain which was selected by the Agricultural University of Hebei, and both the appearance and flavor of its fruit showed a better quality, and its comprehensive economic- character is good. For a comprehensive understanding of its fruit development and growth characters, the botanical characters such as phenological phase, flower bud, flower organ and fruit quality of ＇Baojiajun＇ were studied by using ＇Okubo＇ as the contrast whose fruit maturation period is similar to ＇Baojiajun＇. The results showed that, the shoot growth increment was low, all kinds of bearing branches easily formed flower buds, and its fruit development period was 114 days; in addition, the fxuit of ‘Baojiajun＇ was cling stone, and it had a big size, high content of soluble solids, high tss-acid ratio, big hardness and sweet flavor. So ‘Baojiajun＇ is a new excellent strain.
