11个铁筷子杂交品种的花粉活力及柱头可授性研究
Study on pollen viability and stigma receptivity of 11 Helleborus×hybridus cultivars
摘要
Abstract
Eleven Helleborus×hybridus double-flowered cultivars were selected as experimental materials to investigate and compare their plant and floral morphological characteristics,pollen viability and stigma receptivity.The results showed that the floral and plant traits of'Huajin Meiyin','Huaxue Chuchu',and'Huamei Chazi'were superior to those of other cultivars.Pollen viability measured by the TTC staining method was generally lower than that determined by the in vitro germination method.Except for'Elegance Honey Wine',the pollen in vitro germination rates of the remaining ten cultivars ranged from 81.39％to 99.40％.'Peach Primadress'and'Huaxue Chuchu'exhibited strong stigma receptivity.'Huajin Meiyin','Huaxue Chuchu','White Primadress',and'Peach Primadress'showed excellent comprehensive phenotypic traits and reproductive characteristics,which can be selected as superior parental materials for cross-breeding of Helleborus.These findings provide a theoretical basis for parental selection and combination allocation in the efficient cross-breeding of Helleborus.关键词
