The first factor that influenced callus formation was genotype; the second was growth regulator, and the third was organic nutrient content and sucrose.
基因型是影响愈伤组织形成的主要因素，其次是生长调节物质，再次是有机营养成分和蔗糖；
2
The effect of genotype on the rate of induction, growth and embryogenic callus initiating were different significantly.
小麦成熟胚愈伤组织的诱导率、生长率及胚性愈伤组织发生率的基因型效应有显著差别。
3
Physiological development time was used to simulate growth and development processes of wheat and it unified the physiological time scale for different genotype.
