设施油桃不同品种果实发育特性研究

以设施栽培的五月火、早红珠、丹墨、曙光、早红2号、早红宝石油桃为试材,测定了设施油桃不同品种果实的发育特性,包括果实纵横径与单果重.结果表明:在聊城地区,油桃在果实发育过程中,果实纵、横径逐渐增大,并基本呈"双S"型曲线.单果重持续增加,在花后40 d内,由于果实单果重一直较小,所以果实单果重的净增加值较低,在接下来的30 d内,单果重净增加值较大;在果实将近成熟时,即花后的70～80 d内,果实还会出现一个单果重增长的高峰.

Study on Development Characteristics of Different Nectarine Cultivars in Greenhouse

Used Shuguang nectarine,Wuyuehuo nectarine,Zaohongbaoshi nectarine,Zaohong 2 nectarine,Zaohongzhu nectarine and Danmo nectarine cultivars in greenhouse as the test material,the fruit development characteristics were measured,including equatorial diameter,polar diameter and the weight of single fruit.The results showed:during nectarine fruit development,the equatorial diameter,polar diameter of fruit increased gradually,behaved double S curve.The single fruit weight kept increasing,in the first 40 days after full blossom,the net increase value of single weight was low because the single weight was little.But in the following 30 days,it was high.As it was near mature period,that was 70~80 days after full blossom,the single weight of fruit would gain a climax of increase.
