本文主要研究内容
作者谈慧(2019)在《9种砧用南瓜对甜瓜枯萎病的抗性及嫁接亲和性的鉴定和评价》一文中研究指出:本研究是以课题组前期保存的9种砧用南瓜种质资源为材料,分别以薄皮甜瓜“厂蜜1号”和厚皮甜瓜“好运11”作为接穗,对嫁接苗的嫁接成活率、枯萎病抗性、定植到大田后植株的生长发育、产量和品质进行研究,系统研究9种砧木与甜瓜的嫁接亲和性和共生亲和性,为甜瓜抗病专用砧木品种的选育提供试验基础和理论参考。主要研究结果如下采用插接法进行嫁接,嫁接后10d、15d和20d分别统计嫁接成活率,除NC02和N03T与薄皮甜瓜以及N01与厚皮甜瓜的嫁接成活率均为88.89%,低于90.0%外,其余编号与厚皮甜瓜和薄皮甜瓜嫁接成活率均高于90.0%,说明9份资源中有6份砧用南瓜与薄皮甜瓜和厚皮甜瓜的嫁接亲和性均表现良好,可同时作为薄皮甜瓜和厚皮甜瓜优良砧木选育的备选种质资源。1.采用人工室内苗期伤根法对甜瓜枯萎病抗性进行鉴定,对嫁接苗发病情况连续观察21d,结果显示两种甜瓜自根苗发病率在80%以上,均为感病,而砧穗组合的嫁接植株不论是厚皮甜瓜还是薄皮甜瓜均表现为高抗。经柯赫氏法则鉴定,自根苗茎出现大量病原菌,而以南瓜为砧木的嫁接苗茎上分离到的病原菌较少,说明使用砧用南瓜嫁接甜瓜可有效防治甜瓜枯萎病2.对薄皮甜瓜和厚皮甜瓜各砧穗组合进行栽培试验,研究9份砧用南瓜种质资源对甜瓜嫁接苗植株田间生长发育的影响,对嫁接苗株高、茎粗、叶面积、叶片数、花期、叶片叶绿素、蔗糖和淀粉含量等生理指标进行测定测量,经隶属函数综合评价结果表明,9份砧用南瓜嫁接的厚皮甜瓜和薄皮甜瓜在生长势上均优于其各自的自根苗植株,以NZ02,NC01,NC02,N03T和NC09这5个编号为砧木的砧穗组合在生长发育上的综合表现优于其他编号的砧穗组合3.对各砧穗组合的产量和果实品质进行测定结果表明,9份砧用南瓜对厚皮甜瓜和薄皮甜瓜的口感无明显影响,嫁接苗果实口感与自根苗相比无均显著差异;在矿质营养上,不同砧穗组合在不同矿质元素含量上表现不一,各处理镁元素含量在薄皮甜瓜和厚皮甜瓜的果实中均低于自根苗;对果实营养品质(可溶性固形物、可溶性蛋白、VC、游离氨基酸、可溶性糖、可滴定酸、糖酸比)进行隶属函数综合评价发现,以NC02、NC09和N03T为砧木的嫁接植株在果实营养品质上表现较优。综合以上四部分的试验结果,9份砧用南瓜中,NC09可作为薄皮甜瓜嫁接栽培的优异种质资源,NC02,NC09和N03T可作为厚皮甜瓜嫁接栽培的优异种质资源。
