In order to obtain more and detailed information, the chemical experiment methods were used to analyze the main nutritional components of mineral Ca, Mg, Fe and Vc, acid value in the nuts of 9 Fagaceae species. Some conclusions are as follows:(1) Among the 9 species, the Castanea seguinii nut has the greatest content of Ca, followed by Castanea henryi and Lithocarpus litseifolius, that in the Cyclobalanopsis gracilis nuts is the least; meanwhile, the Castanea seguinii nuts contain the most Mg, followed by Castanopsis sclerophylla and Castanopsis tibetana, but the Castanea henryi nut has the least mineral Mg. In addition, the Castanopsis sclerophylla nuts contain the greatest content of Fe, but the nuts of some species such as Castanea seguinii, Castanopsis eyrei, and Castanea henryi contain also more mineral Fe. (2) the nuts of Castanea seguinii contain rich content of Vc, followed by Castanea henryi. (3) Among these 9 species, Cyclobalanopsis gracilis nuts contain the highest acid value, followed by Cyclobalanopsis glauca, the fruits of Castanea seguinii, Castanea henryi and Castanopsis sclerophylla nuts have the moderate acidity value, which taste better and have a higher development value. In a word, the nuts of these 9 species contain rich mineral nutritional ingredients and Vc. It is considered that these species could meet the need of food industry in great scale.

用天然群落枯枝落叶浸提液浸种与其它处理方法进行伯乐树种子发芽试验,试验分室内和大田萌发试验,室内又进行了不同浸提液、不同激素处理、不同温度处理对伯乐树种子发芽的影响。结果表明:(1)蒸馏水浸种发芽率＞伯乐树群落枯枝落叶浸提液浸种发芽率＞罗浮栲群落枯枝落叶浸提液浸种发芽率,但差异不大;其中蒸馏水处理的种子发芽率最高(69.2%)。(2)以200 mg·L-1 GA3浸种12 h发芽率最高,达到80.0%。GA3浸种的伯乐树种子发芽率＞蒸馏水浸种的发芽＞IAA浸种的发芽率。(3)大田试验的发芽率与室内试验发芽率基本接近;其中酒精浸提液处理的种子发芽率较高,达70.4%。(4)伯乐树发芽最适宜温度是20 25℃。发芽开始后第10 26天为发芽高峰期;发芽可持续32天。(5)在20 ℃条件下第7—14天腐烂率较高;随着温度的升高,高腐烂率出现的时间推迟,但发芽率相对降低。
