摘要:
对浙江省龙泉市营造3 ~ 4年生赤皮青冈Cyclobalanopsis gilva,福建青冈C. chungii和小叶青冈C. myrsinifolia 的58个家系子代幼苗进行生长性状测定,分析生长性状、遗传变异及生长性状间相关性,并对其进行早期选择。结果表明,不同青冈及其家系间生长性状存在丰富的变异,各家系4年生幼苗多数生长性状间呈显著正相关(0.05水平),且树高和当年抽梢高存在显著的表型相关,其中遗传相关和环境相关均达到显著水平。初步筛选出13个生长较优的青冈家系,分别为宁赤3,宁赤2,宁赤4,宁赤10,福赤8,宁赤6,庆小11,宁赤7,庆小9,福赤7,龙小6,庆小1和福赤5。多数为赤皮青冈家系,表明赤皮青冈早期生长优于小叶青冈和福建青冈。4年生的生长性状测定表明,生长性状的早期选择存在较明显的稳定性。
Abstract:
Determinations were implemented on growth traits of 58 families of 3-4-year Cyclobalanopsis gilva, C. chungii and C. myrsinifolia seedlings in Longquan, Zhejiang province. Analysis was made on growth traits, genetic variations and correlation among growth traits and early selection was carried out among tested families. The results revealed that there were rich variations among different families and different speices. 4-year seedlings of different families had positive relation among growth traits (P=0.05). There was obvious phenotypic correlation between height growth and new shoot growth of the current year, and the genetic and environment correlation was evident. 13 families were preliminary selected for their better grwoth, namely Ningchi 3, Ningchi 2, Ningchi 4, Ningchi 10, Fuchi 8, Ningchi 6, Qingxiao 11, Ningchi 7, Qingxiao 9, Fuchi 7, Longxiao 6, Qingxiao 1 and Fuchi 5. Most of then were families of C. gilva, indicating better growth than the other two species. The early selection of growth traits showed evidently stable.
