We study evolutionary games in two-layer networks by introducing the correlation between two layers through the C2dominance or the D-dominance.We assume that in
本试验以黑果枸杞组培苗顶端叶片、组培苗茎尖为试材,以秋水仙素为诱导剂,采用施入法,对黑果枸杞进行多倍体诱导,初步摸索出适合黑果枸杞的多倍体诱导及鉴定方法,并获得了一些多倍体植株,为进一步规模化繁殖及推广奠定了基础。结果如下:1、采用施入法分别处理黑果枸杞组培苗顶端叶片、组培苗茎尖两种材料,其中两种处理材料在秋水仙素溶液浓度为500 mg·L-1,处理7d的存活率均较接近半致死剂量,此为秋水仙素溶液
