摘要
对金银花新品系与主栽品种的叶、茎、花蕾表面腺毛、非腺毛的密度、长度进行观察和分析,并测定其叶的叶绿素、花青素含量和光合速率,为良种的鉴别和鉴定提供依据.结果表明,豫金1号的表皮毛长度、密度均高于对照,豫金2号表皮毛除叶下表面非腺毛长度低于对照亚特红蕾1号,其他均高于对照;豫金1号、豫金2号的叶绿素含量和光合速率分别较对照高,说明在一定范围内,叶片的光合速率随叶绿素含量的增加而提高,叶片花青素含量与光合速率的相关系数达到显著水平(P<0.05),花青素含量与光合速率之间呈负相关.结论:表皮毛的长度、密度等可作为金银花新品种鉴别指标的依据.
By observing and comparing the density length of glandular hairs non-glandular hairs on Lonicera Japonica new strain and major cultivars＂ leaves stem and bud surface, and measure their leaves＂ chlorophyll anthoeyanin content and photo- synthetic rate,which can provide support for improved varieties identification. The results show that, the dens!ty length of epi- dermal hair are higher than its check variety on Yujin No. 1. The density length of epidermal hair were higher than its check va- riety except the length of non-glandular hairs under the leaf surface on Yujin No. 2. The chlorophyll and photosynthetic rate of Yujin No. 1 Yujin No. 2 are respectively higher than their own check variety,it was showed that leaves＂ photosynthetic rate in- creased with chlorophyll content within limits. The correlation coefficients of leaves＂ anthocyanin content has significant differ- ence with photosynthetic rate, there exists negative correlation between them. Conclusion： The length density of epidermal hair can provide the basis for Lonicera Japonica identifying index.
