摘要

甜椒品種‘銘星’與十辣椒品種（品系）砧木嫁接，調查植株生育情形及嫁接處癒合情形。結果顯示‘艷茹’砧之嫁接成活率最低為79.3 %，又定植30天之田間存活率，除 '艷茹'砧之94.4 %外，其他組合皆為100 %。'銘星'嫁接苗以‘百里香’及'百香'砧之始花期顯著提早六天；單株果實初期產量及總產量以`百香`砧顯著最高。解剖觀察`銘星`接穗與M210101砧嫁接後，穗砧接合處形成層及其鄰近之維管束組織的發育情形，發現隨著接合天數增加其新生的細胞和髓部細胞增加，砧穗接合處逐漸產生癒合。此外，以M210101、31346、'百香'及'生生4號'等砧木與銘星接穗嫁接6天後，解剖切片結果顯示'百香'及'生生4號'砧之髓部癒合較早。

'Andalus' sweet pepper scion was grafted on ten hot pepper varieties (strains). The growth of grafted plants and the process of grafting union were examined. The graft success rate and field survival rate of 'Andalus' sweet pepper scion grafted on 'Born Fire' rootstocks were 79.3% and 94.4% respectively. The initial flowering of plants grafted on 'Miles Flavor' and 'Passion' rootstocks were shortened for 6 days. Early fruit yield and total yield of plants grafted on 'Passion' rootstock were increased. The parenchyma cells in the vascular, cambium and pith of plants grafted on M210101 rootstock had wound-repair response and the parenchyma cells proliferate and arrange as days after grafting increased. Especially in the combination of grafted on 'Passion' and '194' rootstocks had early wound-repair response after grafting 6 days compared to that of M210101 and 31346.
