为了开发芦笋种质资源,促进芦笋的遗传改良和育种,本研究采集了3处不同生境下的野生石刁柏(Asparagus officinalis)材料,以内蒙古地区常用的栽培品种(MW.500#-W)为对照,采用随机区组试验设计,在相同的种植和管理条件下,对其果实特征、种子特征及发芽状况及生长速率、株高、侧枝长、枝节间长、萌糵数、花数等指标进行对比观测和分析。结果表明,不同野生石刁柏材料及栽培品种的果实和种子在形态特征及发芽率、发芽势等方面均存在显著差异。栽培品种的生长速率明显快于野生种,但开花和种子生产性能不良,管理难度大。而野生种植株低矮,试材A和试材C开花量大,结实性能优秀。多样性的特征,为石刁柏新品种培育和改良及增加芦笋生产的多样性具有重要意义。
In order to develop germplasm resources of asparagus and promote the genetic improvement and breeding of asparagus, three Asparagus officinalis materials were collected from different habitats in this study. The common cultivars (MW.500 # -W) As a control, using randomized block design, under the same conditions of planting and management, the fruit characteristics, seed characteristics and germination status and growth rate, plant height, branch length, branch length, adorable bud number, flower number, etc. Indicators for comparative observation and analysis. The results showed that there were significant differences in the morphological characteristics, germination rate and germination potential among the fruits and seeds of different wild Asparagus cultivars and cultivars. The growth rate of cultivated species is obviously faster than that of wild species, but the flowering and seed production performance is poor and the management is difficult. The wild plant low, test material A and C flowering large, excellent solid performance. The diversity of the characteristics of asparagus to cultivate and improve the new varieties and increase the diversity of asparagus production is of great significance.
