对6个杂交组合的杂交后代的观察和组织解剖研究表明,圆果黄麻色素减免基因“R”。在黄麻不同生育阶段对决定花青素分布强度的“A”不同复等位基因的减免作用不同。在苗期和后期。“R”基因的减免作用主要是减少花青素细胞的数量,对“A”基因的不同复等位基因,花青素细胞减少的数量不同;因此,尽管有“R”基因存在,由于“A”复等位基因的不同.F_1茎色的表现也不同,在旺长期阶段,由于“R”基因作用明显加强,不仅使花青素的细胞数量减少,而且花青素细胞内色素的浓度也受到抑制,“A”的不同复等位基因之间差异不明显,因此茎的表现为绿色.
Observations and histological studies on the hybrid progeny of six crosses showed that the fructus cirrhosae gene attenuated the “R” gene. The effects of different alleles of “A” on the distribution intensity of anthocyanins were different at different growth stages of jute. In the seedling and later. The reduction effect of “R” gene is mainly to reduce the number of anthocyanin cells, and to different numbers of alleles of “A” gene, the number of anthocyanidin cells is reduced. Therefore, despite the presence of “R” A “allele.The expression of F_1 stem color was also different. In the long-term phase, the role of” R “gene was significantly enhanced, not only to reduce the number of anthocyanin cells, but also anthocyanin intracellular pigment concentration Also inhibited, ”A" different complex allele is not obvious, so the performance of stems green.
