The results were summarized as follows:1 Four cpDNA trnL-F, matK, rbcL, and atpB sequences analysis The chloroplast trnL-F, matK, rbcL, and atpB sequences from 31 species representing nearly all genera of Fagales (sensu APG, 2003) were used to reconstruct the phylogeny of the order.
主要内容包括:1 基于四个叶绿体DNA序列的分析以金缕梅属Hamamelis和朴树属Celtis为外类群,对壳斗目几乎所有属的代表共31种植物的trnL-F、matK、rbcL和atpB序列进行了测定,通过四个序列单独和联合分析,得到如下结果:除rbcL基因树由于信息位点少而分辨率较低之外,壳斗目各科作为单系类群在各种分析中都得到了较强的bootstrap支持。

Female inflorescences of 1-7 or more flowers subtended individually or collectively by a cupule formed from numerous fused bracts, arranged individually or in small groups along an axis or at base of an androgynous inflorescence or on a separate axis. Female flower: perianth 1-7 or more; pistil 1; ovary inferior, 3-6(-9)-loculed; style and carpels as many as locules; placentation axile; ovules 2 per locule. Fruit a nut. Seed usually solitary by abortion (but may be more than 1 in Castanea , Castanopsis , Fagus , and Formanodendron ), without endosperm; embryo large.

The result shows that the chitosan can increase the the amount of effective tiller, then the yield of both of cultivars of Zizania caduciflora is enhanced markedly, and the concentration of 45mg/L of the chitosan has the best effect. The activity of POD in leaves and the content of sucrose in product can be increased after using the chitosan, and the change of the chlorophyl content could be abated and the effect has a long duration, and the furthersome effect of chitosan on the activities of the CAT and the APX lasts in the prophase and the midphase of growth.
结果显示壳聚糖的使用对单季茭和双季茭的有效分蘖数都有增加作用,从而明显提高茭白产量,并且均以45mg/L的浓度效果最好,其使用能显著提高两种类型茭白生长期叶片中POD酶的活性以及茭体中的蔗糖含量;壳聚糖对茭白叶绿素有缓和变化波动的作用且持效久,对茭白CAT、APX酶活性的促进作用只在处理前中期有效;而对株高和A.A。
