摘要
为了解果实性状的形成规律及性状间的相关规律,以深州蜜桃实生后代为材料,从第一次结果开始,逐年记载各单株的开花期、成熟期、单果重、甜酸味、可溶性固形物含量、香味、苦味、果汁、着色度、果形和果顶形状,并在年度间进行趋势分析、相关分析和通径分析。结果表明:随实生树结果年龄的增加,果实生育期相对稳定,果实的内部品质有提高的趋势,外观品质受当年树体条件和环境条件的影响较大,多数果实性状在年度间表现了不同的相关和决定程度。
The fruit characters(florescence, maturation period,weight per fruit,sweetness,the soluble solids content,fragrance,bitter,fruit juice,coloring rate,fruit shape and fruit top shape)during the initial 4 years of fructifying in seedling of Shenzhoumi peach was investigated and analyzed by the method of correlation or direct path.The results showed that the fruit growth phase was relatively stable,the fruit internal quality increased gradually,the fruit external quality was influenced considerably by the conditions of tree and environment.Most fruit characteristic showed the correlation and decisiveness on different degrees during per year.
