摘要
以塞罕坝自然保护区的5种忍冬科植物为试验材料,移植1a后进行观察,研究其开花、结实特性,以及对新环境的适应能力,为引种栽培提供科学依据。结果表明:叶芽萌发最早的是接骨木,最晚的是蓝靛果忍冬;花期最早开始的是接骨木和蓝靛果忍冬,花期最晚的是藏花忍冬;果实最早成熟的是蓝靛果忍冬,最晚的是蒙古荚蒾;花期持续时间最长的是金花忍冬,达到了15d,最短的是接骨木和蓝靛果忍冬,只有9d;果实发育期最短的是藏花忍冬,只有29d,最长的是金花忍冬,达到了94d;总体来看,金花忍冬的生长状况最差,最好的则是接骨木。
5 kinds of Caprifoliaceae plants in Saihanba nature reserve as the experimental materials, in the next year, the flowering and seed setting characteristics were observed, and the adaptation to the new environment, in order to provide scientific basis for introduction and cultivation. The results as followes: when bud germination ,the earlist one is Sambucus williamsii Hance and the latest one is Lonicera caerulea L. var. enulis Turcz et Herd;Sambucus williamsii Hance and Lonicera caerulea L. var. enulis Turcz et Herd were flowering earlier, but the latest one was Lonicera tatarinowii. When the fruit were ripe, Lonicera caerulea L. var. enulis Turcz et Herd was the earlist one and Viburnum mongolicum(Pall.)Rehd.was the latest one. The longest flowering period was Lonicera chrysantha Turcz., which reached 15 days, the shortest ones were Sambucus williamsii Hance and Lonicera caerulea L. var. enulis Turcz et Herd,which only were 9 days. Fruit development period can be from 29 days to 94 days, wich were Lonicera tatarinowii and Lonicera chrysantha Turcz.. The growth status of Lonicera chrysantha Turcz. was the worst, and the bestest one was Sambucus L..
