| 摘 要： | 收集8个种源地7个栎属树种(蒙古栎、栓皮栎、短柄抱栎、槲栎、锐齿槲栎、辽东栎、橿子栎)在保定市进行了栽培试验。结果表明，不同种源地栎属不同树种在出苗时间、出苗率及高生长过程等方面存在显著差异。出苗最早的雾灵山蒙古栎与出苗最晚的武安栓皮栎相差15 d，帽儿山蒙古栎出苗时间比原产地提前37 d；不同种源地栎属树种出苗持续时间存在较大差异，雾灵山蒙古栎出苗持续时间最长，为65 d，而宝天曼短柄抱栎的持续时间只有30 d；不同种源地栎属树种的高生长过程基本一致，都经历一个慢-快-慢的生长节律，多数都在40 d以内完成高生长，但高生长持续时间有较大差异。出苗率及苗期高生长量与种子千粒重相关关系显著，千粒重越大，高生长量越大，千粒重中等的种子出苗率最高，千粒重较小和较大的种子出苗率都比较低。综合幼苗期各方面的特征来看，雾灵山蒙古栎在保定地区表现较好，适用于该地区造林。

| Abstract: | To understand the differences of Quercus species in emergence and height growth,7 species of Quercus (Q. mongolica，Q. variabilis， Q. glandulifera var. brevipetiolata，Q. aliena，Q. aliena var．acuteserrata, Q. liaotungensi，Q. baronii) distributed in 8 provenances (Maoershan Mountain of Heilongjiang, Changbai Mountain of Jilin, Benxi Caohekou of Liaoning，Laotudingzi National Nature Reserve of Liaoning, Wu’an of Hebei , Chengde Wuling Mountain of Hebei，Jiyuan of Henan, Baotianman Nature Reserve of Henan) were collected and cultivated in Baoding of Hebei. The results showed that there were significant differences in emergence time, emergence rate, height growth processes among them. The seedlings of Q. mongolica from Wulingshan came out 15 days earlier than Q. variabilis from Wu’an, and the seedlings of Q. mongolica from Maoershan came out over 30 days earlier in Baoding than in its origin location. The longest emergence duration was Q. mongolica from Wulingshan ( 65 days), and the shortest one was Q. glandulifera var. brevipetiolata (30 days) from Baotianman. There was a similar height growth process among species with a low-high-low pattern, and most of them completed height growth within 40 days with different durations. There was a positive significant relationship between height growth and thousand kernel weights of seeds, and a relationship between emergence rates and thousand kernel weights of seeds. The seeds with medium seed weight had the highest emergence rate, and both lower seed weight and higher seed weight had lower emergence rates. Based on the performance during the seedling, Q. mongolica was considered as a suitable one for afforestation in the Baoding. |
