摘　　要：为探明本文作者前期研究中获得的丹参组织培养再生苗是否会出现性状变异,将丹参组织培养再生苗与野生植株间进行了性状对比研究,丹参组织培养再生苗经温室驯化和大田栽培,发现其部分生物学性状发生变异,表现为:试管苗驯化植株冠幅较大,高度明显变矮且茎部粗壮,根部表现出强烈分生能力,叶片由5出叶变为3出叶为主,叶形由长椭圆形变为卵圆形。说明组织培养过程可以造成生物学性状的改变。Some tissue culture regeneration plantlets of Salvia miltiorrhiza were obtained in our previous study, some character- istics of these tissue culture regeneration plantlets of salvia miltiorrhiza varied after being domesticated in the glasshouse and field. The obvious changes were showed, i.e. in coronal breadth broadening, height shortening, stems thickening, roots re- markably tillering~ leaves pinnate becoming ternate from previous 5-foliolate, leaf shape becoming ovate from previous oblong oval, which proved that tissue culture process might lead to the variation of biological characteristics.
