调查瓜列当对新疆甜瓜的危害,探索瓜列当化学防控方法,为瓜列当防治措施制定及实施提供技术支撑。以新疆伽师县4个甜瓜主产乡镇为代表,调查瓜列当对甜瓜的危害程度及规律。结合新疆甜瓜栽培模式,进行2种除草剂各2种浓度对瓜列当的防治... 详细信息

调查瓜列当对新疆甜瓜的危害,探索瓜列当化学防控方法,为瓜列当防治措施制定及实施提供技术支撑。以新疆伽师县4个甜瓜主产乡镇为代表,调查瓜列当对甜瓜的危害程度及规律。结合新疆甜瓜栽培模式,进行2种除草剂各2种浓度对瓜列当的防治试验。调查的4个乡镇瓜列当都有不同程度的发生。甜瓜播种后50 d直到收获,都有瓜列当寄生危害。75%磺酰磺隆和甲基咪草烟都可用于对甜瓜列当的防治,磺酰磺隆效果优于甲基咪草烟。结合浇水冲施37.5 g a.i.·hm-275%磺酰磺隆,是最有效的新疆甜瓜瓜列当化学防治的施用方式和浓度。

【目的】基于聚乙烯袋水培法研究甜瓜不同品种对列当的抗性鉴定方法,为甜瓜抗列当品种选育提供技术支撑。【方法】利用聚乙烯袋水培法,研究不同甜瓜品种根系分泌物对埃及列当种子萌发诱导活性及寄生的影响,评价甜瓜品种抗性。【结果】聚乙烯袋水培9个接种埃及列当种子的甜瓜品种,其根系分泌物都可刺激列当种子发芽,但瘤状茎数量差异显著。用瘤状茎数量评价9个甜瓜品种对埃及列当的抗性,结果表明,参试甜瓜品种对列当寄生的抗感性存在差异,k2-2、k2-7及CEZ这3个品种抗性优于其他品种。【结论】聚乙烯袋水培法可作为有效的甜瓜列当抗性室内鉴定方法。

目的与意义:西瓜(Citrullus lanatus)果实中的可溶性糖积累是西瓜长期驯化过程中主要品质性状之一.目前,关于西瓜中糖转运蛋白是如何调节果实中各种糖积累的这一机制尚不清楚,特别是像西瓜这种储存高浓度蔗糖的作物.笔者旨在缩小已报道的糖含量QTL的区间,以及构建超高密度SNP遗传图谱来确定QBRX2-1 QTL的决定基因,并阐明西瓜驯化过程中糖分积累的分子机制.
