黄檗不同家系子代生长性状比较

Growth Traits of Phellodendon amurense in Different Family Progeny

通过不同子代幼苗苗高和地径对比,分析黄檗种源间、家系间和家系内个体间生长性状变异规律.结果表明:不同种源间苗高差异不显著,地径差异显著(F=41.22^(**)),临江黄檗幼苗苗高和地径均值均大于黑龙江黄檗;种源内不同家系间苗高的差异均达到极显著水平(F=34.74^(**)和F=34.48^(**)),黑龙江种源12号(H-12)在所有家系中苗高表现最好,临江种源中优良家系数量较多.两个种源内不同家系间地径的差异也达到极显著水平(F=9.19^(**)和F=15.40^(**)),临江种源1号家系(L-1)幼苗地径最大,黑龙江种源12号家系(H-12)幼苗地径最大;黄檗幼苗苗高与地径呈极显著正相关(相关系数为0.67^(**)).在优良家系内苗高最优良单株是黑龙江种源12号家系第1号单株(H-12-1),苗高为95 cm;地径最优良的单株是临江种源第22号家系第17号单株(L-22-17),地径为10.47 mm.

Through the comparison of different Phellodendron amurense progeny saplings, the height and base diameter, the growth traits variation of provenances, families and individuals were investigated. The results indicated that there was no significant variation in height between two provenances, and there was significant variation in base diameter（ F=41.22 ＊＊ ）between two provenances. The mean diameter of Linjiang saplings was higher than that of Heilongjiang individuals. Height of different families in two provenances were significant variation （F= 34.74＊＊ , F= 34.48 ＊＊ ）, No. 12 （H-12） family of Heilongjiang provenance showed the best in all families,and a large number families of Linjiang provenances were superior families. Base diameter of different families in two provenances was significant variation （ F=9.19＊＊ ,F= 15.40 ＊＊ ） ,base diameter of L-1 and H-12 family was largest in Linjang and Heilongjiang provenance, respectively. There was significant positive correlation between height and base diameter （0.67 ＊＊ ）. In superior families, the highest sapling was H-12-1 which was 95 cm and the largest diameter sapling was H-12-1 which was 10.47 mm.
