| 摘 要： | 本研究以选育的藤椒少刺优良无性系‘丹林1号’和‘丹林2号’为试材,系统对比了枝刺、叶刺及结实特性。结果表明:(1)‘丹林1号’和‘丹林2号’皮刺数、皮刺宽、皮刺长宽比均与对照CK差异显著,两者之间差异不显著,枝条皮刺数分别比CK减少72.72%、70.91%;‘丹林1号’、‘丹林2号’和CK皮刺长、皮刺间距三者之间差异显著,刺间距分别比CK增加81.14%、37.96%。(2)‘丹林1号’和‘丹林2号’复叶小叶数以3片居多,叶片及叶轴均无刺,CK复叶小叶以5片为主,具细小叶刺。(3)‘丹林1号’、‘丹林2号’和CK之间果穗长和果穗宽差异显著,其中‘丹林2号’果穗长和果穗宽最大,分别为12.54 cm、7.87 cm;‘丹林1号’和‘丹林2号’果穗均无刺,平均果粒数为98~101粒之间,与CK差异显著。

| Abstract: | The aim of this study was to systematically compare branch prickles,leaf prickles and fruiting characteristics of‘Danlin No.1’and‘Danlin No.2’,which were selected as test Zanthoxylum armatum DC.materials with fewer prickles.The results showed that(1)the prickle number,prickle width and prickle length-width ratio of‘Danlin No.1’and‘Danlin No.2’were significantly different from the control,and the differences between them were not significant.The number of prickles on branches was 72.72%and 70.91%lower than CK respectively.There were significant differences among‘Danlin No.1’,‘Danlin No.2’and CK at prickle length and prickle distance.The prickle distance was 81.14%and 37.96%higher than CK respectively.(2)The number of compound leaf leaflets of‘Danlin No.1’and‘Danlin No.2’was three at most cases,with no prickle on leaves and rachis.But CK compound leaf leaflets were mainly five,with tiny leaf prickles.(3)There were significant differences in ear length and ear width among‘Danlin No.1’,‘Danlin No.2’and CK,with‘Danlin No.2’having the largest ear length and ear width,which were 12.54 cm and 7.87 cm respectively.‘Danlin No.1’and‘Danlin No.2’had no prickle cluster,and the average number of fruit was between 98 and 101,which was significantly different from CK. |
