砧木(rootstock)
砧木(rootstock)嫁接繁殖时承受接穗的植株。砧木可以是整株果树，也可以是树体的根段或枝段，起固着、支撑接穗并与接穗愈合后形成植株生长、结果。砧木是果树嫁接苗的基础。苹果矮化砧木，抗葡萄根瘤蚜的砧木，抗柑橘根线虫的砧木以及耐寒性强的砧木利用促进了果树的发展。嫁接繁殖的果树，靠砧木的根系从土壤中吸收水分和矿质营养，进行生命活动。砧木本身某些方面的特性，如对旱、涝、低温、盐碱以及病虫的忍耐和抗拒能力，直接影响果树的抗性和适应性。还直接影响树体的生长、结果及寿命。砧木可以使嫁接树的树体长得高大，也可以使树体长得矮小，同一品种嫁接在不同砧木上，树高和树冠体积会相差数倍；并且对枝条萌发的数量和组成比例、生长物候期以及树体姿态都有明显影响。砧木对果树的开始结果时期、坐果率、产量、果实成熟期、色泽，品质以及贮藏能力等都有一定影响。砧木对嫁接树的寿命有很大影响，如石楠作枇杷的砧木，寿命长达80年以上，而共砧仅40-50年；果树栽培中利用的砧木有二类：一类是实生繁殖的砧木；另一类是无性繁殖的自根苗或称无性系砧木。根据利用方式不同，把连同根系用作砧木的，称基砧，只用一段条嵌在基砧与接穗之间的称中间砧。能够使接穗长成5m左右高大树冠的砧木称乔化砧，使树冠长得比乔化砧树冠小1/3的砧木称半矮化砧。使树冠长得仅为乔化砧树冠1/2的称矮化砧。对不良环境条件或某些病虫害具有良好适应能力或抵抗能务的砧木，称抗性砧木。嫁接苹果常用的砧木：山荆子、楸子、花红、河南海棠、湖北海棠、海棠花等；嫁接梨常用的砧木：秋子梨、杜梨、褐梨、麻梨、沙梨、豆梨等；嫁接桃常用的砧木：杏、扁桃、山桃、梅等；嫁接柑橘类常用的砧木：枳、枳橙、酸橘、甜橙、酸柠檬、橙子、柚等。
