大量试验证明,组织培养过程中可以产生许多变异.Burk和Matzinger首先在烟草的46个体细胞再生植株中,发现了广泛的表型变异.尔后,其他作物如甘蔗、小麦等,均发现有体细胞再生植株的变异.在水稻组织培养研究中,Oono首先报道了利用水稻去壳种子诱导愈伤组织进而分化成的再生植株,在株高、抽穗期、小穗育性、形态等表现了广泛的变异.赵成璋等对栽培稻品种的幼穗产生的体细胞再生植株后
Numerous experiments have shown that many variations can occur during tissue culture, and Burk and Matzinger first found extensive phenotypic variation in 46 somatic cell-regenerated plants of tobacco, followed by other crops such as sugarcane and wheat that found somatic cells Oono first reported the regeneration of callus induced by rice hulled seeds and then differentiated into plant regeneration, which showed a wide range of plant height, heading date, spikelet fertility and morphology Variation .Zhao Chengzhang and other cultivated rice varieties of young plants generated by somatic cell regeneration
