不同花色兴安杜鹃种间种内生长与生理变异
Growth and Physiological Variation among and within Intraspecies Varieties of Rhododendron dauricum with Different Flower Colors
摘要
Abstract
To explore the growth and physiological variations among and within intraspecies varieties of Rhodo-dendron dauricum with different flower colors,and provide a reference for new varieties breeding of Rhododendron dauricum.The saplings of three half-sib families from Rhododendron dauricum var.albiflorum and Rhododendron dauricum were measured for the determination of growth traits,light response curve parameters,chlorophyll content,anthocyanin content,and proanthocyanidin content.The petals and leaves of the B1 and B3 families from Rhododendron dauricum var.albiflorum were significantly larger than those of Rhododendron dauricum,and the height and base diameter of the three half-sib families from Rhododendron dauricum var.albiflorum were inferior to those of Rhododendron dauricum.Compared with Rhododendron dauricum,the light saturation point and light compensation point of Rhododendron dauricum var.albiflorum significantly reduced,and the maximum net photo-synthetic rate,apparent quantum yield and chlorophyll content significantly increased.The lower anthocyanin level and higher proanthocyanidin level might be the reasons for variation in flower color of Rhododendron dauricum var.albiflorum.关键词
