The global floriculture market is expected to reach US$41.1 billion by 2027 at a CAGR of 5% over the analysis period 2020-2027; on the year 2020, the recorded market value in this trade was US$29.2 billion. The florists mainly use Anthurium andraeanum flowers in fashionable bouquets and floral arrangements because of their beautiful, attractive bright colored eye-catching spathe, candle-like spadix, prolonged vase life, etc. The cut flower industry always seeks elite cultivars and new hybrids of A. andraeanum, that in turn depend on the availability of large numbers of clonal planting propagules. In vitro somatic embryogenesis is an important technique for large-scale clonal propagation, development of transgenic plants, creation of new variety by somaclonal variation, mutagenesis on in vitro plants, and germplasm preservation for future use. Here, we describe the protocol of somatic embryogenesis of Anthurium andraeanum cv. Cancan, an important commercial cultivated variety. The protocol has been optimized by using 4 different types of culture media which are used during embryogenic callus induction, multiplication of callus, induction of somatic embryogenesis, and maturation plus conversion of embryos into plantlets. The protocol outlines the detailed methods from mother plant procurement to hardening of micro plants that is ready to transfer in the field and it can be used for large-scale commercial propagation.
预计到2027年,全球花卉市场规模将达到411亿美元,在2020 - 2027年的分析期内年复合增长率为5%;2020年,该行业的市场价值为292亿美元。由于花烛美丽、鲜艳夺目且具吸引力的彩色佛焰苞、蜡烛状肉穗花序以及较长的瓶插寿命等特点,花店主要将其用于制作时尚花束和插花。切花行业一直寻求花烛的优良品种和新杂交种,这反过来又依赖于大量克隆种植繁殖体的供应。体外体细胞胚胎发生是大规模克隆繁殖、转基因植物培育、体细胞无性系变异创造新品种、体外植物诱变以及种质保存以备未来使用的重要技术。在此,我们描述了重要商业栽培品种花烛‘康康’的体细胞胚胎发生方案。该方案通过使用4种不同类型的培养基进行了优化,这些培养基分别用于胚性愈伤组织诱导、愈伤组织增殖、体细胞胚胎发生诱导以及胚胎成熟和转化为小植株。该方案概述了从母株采购到微型植株硬化(准备移栽到田间)的详细方法,可用于大规模商业繁殖。
