部分石竹品种农艺性状的变异

摘要

自古以来，人类对花卉和观赏植物的园艺一直充满热情。观赏植物(花卉植物)的经济重要性一直在增加，随着时间的推移，其在世界范围内的国际需求迅速扩大。世界花卉作物的发展趋势和生产中心在不断变化。国际花卉市场的一个可预见的趋势是对质量的日益重视。影响采后保鲜质量的品质因素包括环境对花寿命的影响，以及病原微生物(包括病毒病)的影响。随着世界市场竞争的加剧，质量已成为一个更为重要的因素。增加盆栽植物的花瓶寿命或花的寿命是一个重要的目标。建立了一大批以温室技术为基础的花卉出口单位。这些发展对露天条件下的花卉栽培产生了影响，因此花卉栽培部门出现了显著增长，目前在生产技术、包装和储存、产品品种和质量、产量和销售机制方面正在发生变化。在这个最新的平台上，石竹科双科植物成员石竹(石竹)是一种重要的、以商业季节为基础的花卉作物。 It grows well in temperate climate all over the world and popular as cut-flowers for its variegated petal‟s colour. So, it has terrific market demands in international trading. In this modern era, an agronomic demand of high yielding cultivar of this crop was noticed. Development of cultivars with more desirable floral characteristics and higher productivity are also very important in this crop. Various biometrical/agrometrical characters viz. growth parameters (mature plant height, number and length of shoots and internode, number of tillers, nodes, leaves, stem diameter, length-breadth of leaf etc.), flowering parameters (days to flowering, bud opening, flower development, flower longevity etc.), flower quality parameters (length, girth and diameter, weight of flower, petal number, calyx splitting etc.) and yield parameters (number of flower/plant and seeds/inflorescence, seed weight etc.) were varied greatly from cultivar to cultivar. These parameters serve as key traits for crop improvement programme in which mutation breeding plays a vital stage.
