蜜蜂,壁蜂花期传粉技术研究 总被引:1,自引:0,他引:1
1995~1998年进行利用蜜蜂、壁蜂花期传粉及人工授粉技术的研究,4年的研究结果表明,利用蜜蜂、壁蜂花期传粉及人工授粉可较大幅度的提高果树坐果率及产量。蜜蜂、壁蜂花期传粉与人工授粉在提高坐果率及产量方面无差异,而且利用蜜蜂、壁蜂传粉可节省60%的授粉成本。 相似文献

辣椒的杂种优势很强,杂交辣椒已经得到广泛的推广栽培。过去大都采用人工去雄杂交制种,近年来,随着育种技术的不断发展,育种途径逐渐更新,辣椒雄性不育系包括雄性不育两用系和核质互作雄性不育系(简称三系)育种技术,得到了更广泛的应用。辣椒雄性不育系制种具有保证杂交种的纯度,提高制种产量,降低制种成本,防止亲本流失等特点。如何发挥这些优势,研究形成一套系统、完备的辣椒雄性不育系制种技术就显得尤为重要。 相似文献

The percentage of ovules that set seeds per fruit has been used to evaluate the bumblebee activity of a two campaigns greenhouse trial. The experiment was carried out with two commercial cultivars of sweet pepper, ‘bell’ type, called Bardenas and Vergasa. The averages of the percentages of seed set per fruit of the two campaigns were 49.8% (Bardenas) and 40.7% (Vergasa) on the pollination treatment, whereas the averages of the control (self-pollination) treatment were 27.5% and 25.7%, respectively. Percentages of seed set per fruit was strongly related with the number of bee visits, but weakly with duration of visits. 相似文献

Fruit set represents the very first step of fruit development. This study investigated the effect of different fruit-setting methods [1-(2-chloro-4-pyridyl)-3-phenylurea (CPPU) treatment, artificial pollination, and honey bee pollination] on the concentrations of fructose, glucose, and sucrose, and the activities of sucrose metabolising enzymes of watermelon fruit under plastic film greenhouse conditions. No significant difference in fructose and glucose concentrations was observed among the three treatments at fully ripe stage of fruit [33 days after anthesis (33 DAA)]. However, artificial and honey bee pollination significantly increased sucrose concentration. Measurement of sucrose metabolising enzyme activities and correlation analysis demonstrated that the increased activity of SuSy-s (sucrose synthase, synthesis direction) is the key mechanism of increased sucrose concentration in the artificially pollinated and honey bee pollinated fruits. The concentrations of fructose, glucose, and sucrose were similar between artificially pollinated and honey bee-pollinated fruits at fully ripe stage (33 DAA). Therefore, we can conclude that artificial and bee pollination can improve the sweetness of watermelon fruit. In addition, the honey bee can provide a pollination service that is similar to that of artificial pollination for watermelon grown in a protected cultivation system. 相似文献

摘要:为了提高番茄杂种种子的纯度和产量,需要确定适宜的去雄时间。以番茄杂交组合SD-26-38的父母 本为材料,分别在日光温室内和露地设置开花前2 d上午、开花前2 d下午、开花前1 d上午、开花前1 d下午4个 去雄时间,在开花当天上午9:00—10:00进行授粉,研究不同去雄时间对坐果率及单果种子数的影响。结果 表明:无论是日光温室内还是露地条件下,在开花前1 d下午去雄的番茄坐果率、平均单果种子数均最高,温 室条件下分别为96.0%和134.9粒,露地条件下分别为60.7%和88.7粒。各处理杂种种子纯度均为100%,满足生 产需求。综合得出,在番茄开花前1 d下午人工去雄的制种效果最好。 相似文献

猕猴桃授粉方式筛选 总被引:1,自引:0,他引:1
以红心猕猴桃为试材,设置了5种不同的授粉方式,研究不同授粉方式对红心猕猴桃坐果率、果实外观性状、内在品质及产量的影响,以期为猕猴桃优质高产技术研究提供参考。结果表明:在5种授粉方式中,人工点粉处理猕猴桃的坐果率和单株产量达到最高值,分别为77.12%和30.50kg;从果实外观来看,3号花粉悬浮液(白砂糖2g·L-1+硼酸1g·L-1+琼脂2g·L-1+0.2g·L-1吲哚丁酸+花粉2g·L-1)喷雾授粉果实的横径和单果质量的最大,分别为5.17cm、85.70g;从果实内在品质来看,可溶性固形物含量和可滴定酸含量最高的处理为人工点粉处理,分别为17.2%和0.82%,而总糖含量和维生素C含量最高的处理为1号花粉悬浮液喷雾处理,分别为13.28%和1.12mg·g-1。综合分析可知,利用人工喷雾等器械授粉能更好地节约生产成本,提高猕猴桃的坐果率,增加产量,有效改善果实的外观性状和内在品质,因此认为1号花粉悬浮液(白砂糖2g·L-1+硼酸1g·L-1+琼脂2g·L-1+花粉2g·L-1)处理更适宜用于猕猴桃大面积大规模生产。 相似文献
