摘要
为探究西藏墨脱不同区域的香橼接穗在拉萨嫁接之后的成活率及砧木、接穗、叶片的情况,以筛选出在拉萨适应性较强的墨脱香橼。本研究以墨脱的野生枳树实生苗为砧木,以墨脱县境内墨脱村、地东村、亚东村、江新村4个区域采集的香橼枝条为接穗进行嫁接。通过对香橼的成活率、砧木高、接穗高、接穗粗、香橼叶长宽、香橼叶片数以及是否封顶、是否有刺等指标进行测量,结果表明:48份墨脱县香橼中砧木高度由高到低依次为地东村、墨脱村、亚东村、江新村,接穗高由高到低依次为地东村、江新村、墨脱村、亚东村,接穗粗由大到小依次为江新村、墨脱村、地东村、亚东村,香橼叶长由长到短依次为墨脱村、亚东村、地东村、江新村,香橼叶宽依次为由大到小依次为墨脱村、亚东村、地东村、江新村,叶片数由多到少依次为地东村、江新村、亚东村、墨脱村。叶片未封顶的有5份,占10.42%,叶片已封顶的有43份,占89.58%;刺多的有6份,占12.50%,刺少的有14份,占29.17%,无刺的有28份,占58.33%。在拉萨适应性较强的是墨脱县地东村接穗。
To explore the survival rate of citron scions from different areas of Medog,and the situation of rootstocks,scions and leaves after grafting in Lhasa,so as to screen out Medog citron with strong adaptability in Lhasa.In this study,wild Poncirus trifoliate seedlings in Medog were used as rootstocks,and citron branches collected from Medog Village,Didong Village,Yadong Village and Jiangxin Village in Medog County were used as scions for grafting.The survival rate,rootstock height,scion height,scion diameter,citron leaf length and width,citron leaf number,cap and thorn were measured.The results showed that the rootstock height of 48 citrons in Medog County in descending order was Didong Village,Medog Village,Yadong Village,Jiangxin Village,and the scion height in descending order was Didong Village,Jiangxin Village,Medog Village,Yadong Village.The length of citron leaves in descending order is Medog Village,Yadong Village,Didong Village,Jiangxin Village,the width of citron leaves in de-scending order is Medog Village,Yadong Village,Didong Village,Jiangxin Village,and the number of leaves in descending order is Didong Vil-lage,Jiangxin Village,Yadong Village,Medog Village.5 leaves were not capped,accounting for 10.42%,and 43 leaves were capped,accounting for 89.58%.There are 6 with more thorns,accounting for 12.50%,14 with less thorns,accounting for 29.17%,and 28 without thorns,accounting for 58.33%.In Lhasa,the scions in Didong Village,Medog County have strong adaptability.
