摘  要：
分别以南瓜杂交种(Cucurbita maxima×C.moschata)青农2号、青农3号为砧木,以西瓜(Citrullus lanatus)品种京欣2号为接穗,对2种砧木嫁接的西瓜苗分别接种摩西管柄囊霉(Funneliformis mosseae)、地表球囊霉(Glomus versiforme)、根内球囊霉(Glomus intraradices),以不接菌的嫁接苗为对照,评价不同丛枝菌根真菌(arbuscularmycorrhizalfungi,AMF)对西瓜嫁接苗生长和光合作用的改善效应。结果表明,接种AMF能促进西瓜嫁接苗的生长和光合作用,其中,地表球囊霉的效应最大。青农2号嫁接苗接种地表球囊霉处理的生物量显著高于其他处理,AMF侵染率、净光合速率(Pn)、气孔导度(Gs)、胞间CO2浓度(Ci)、瞬时水分利用效率(WUE)、叶绿素相对含量(SPAD)等亦不同程度高于其他处理,青农2号嫁接西瓜苗接种地表球囊霉的组合在西瓜育苗生产中具有较好的应用前景。

摘  要：
Pumpkin hybrid (Cucurbita maxima× C.Moschata),‘Qingnong No.2’and ‘Qingnong No.3’were taken as stock,and watermelon(Citrullus lanatus)‘Jingxin No.2’was taken as cion.Watermelon seedlings grafted with these 2 stocks were inoculated with Funneliformis mosseae,Glomus versiforme and Glomus intraradices,respectively.The grafted seedlings without inoculation with any of arbuscular mycorrhizal fungi(AMF)were taken as the control.The effect of different AMF on the growth and photosynthetic index of the grafted watermelon seedlings were evaluated.Results showed that AMF inoculation could enhance the growth and photosynthesis of the grafted watermelon seedlings.Among them,the effect of G.versiforme was maximum.The biomass of ‘Qingnong No.2’inoculated with G.versiforme were significantly higher than that of the other treatments.Its AMF infection rate,Pn,Gs,Ci,WUE and SPAD were higher than that of the other treatments by different degree.Therefore,it is considered that the combination of‘Qingnong No.2’inoculated with G.versiforme has better application prospect in the production of watermelon seedlings.
