郁金香切花栽培新技术 总被引:1,自引:0,他引:1
郁金香别名洋荷花,为百合科郁金香属植物,是重要的秋季球根花卉,其品种繁多,花期早,最宜作切花、花境、花坛布置或草坪边缘自然丛植.花色有红、橙、白、紫、黑各单色和复色.花形有杯形、碗形、球形等.郁金香刚劲挺拔的花茎,从秀丽素雅的叶丛中抽出,顶拖着荷花般的花朵,色彩丰润、美丽端庄,是世界著名切花之一,具有较高的观赏价值.其商品化生产前景广阔,是花卉生产者的又一增收途径. 相似文献

为了探究芋种质资源颜色性状的变化规律,以保存在国家种质武汉水生蔬菜资源圃的300多份芋种质资源为材料,按照《农作物种质资源鉴定评价技术规范芋》对芋种质资源的颜色性状进行观察和归类,并重点对芋的叶心色斑颜色、叶柄中下部颜色及母芋芽色的相关性进行总结和探讨。根据叶柄中下部颜色将滇南芋分为绿柄野芋(白芽类型)、乌绿柄野芋(红芽类型)和紫柄野芋(白芽类型)3个类型;将芋中的多子芋分为绿柄多子芋(一般为白芽类型)、乌绿柄多子芋(一般为红芽类型)和红紫柄多子芋(白芽类型)3个基本类型,将芋中的多头芋分为绿柄多头芋(白芽类型)和乌绿柄多头芋(红芽类型)2个类型。从滇南芋和芋的整体来看,只要叶柄中下部颜色含有乌绿色成分,则母芋芽色一般为红色类型。从叶心色斑颜色来看,滇南芋中的绿色者,母芋芽色为白色类型;紫红色或紫色者,母芋芽色可能为白色类型,也可能为红色类型。芋中,多子芋叶心色斑颜色为紫红色者,母芋芽色为红色类型;黄绿色或绿色者,母芋芽色为白色类型。多头芋中,叶心色斑颜色为绿色者,母芋芽色为红色类型;紫红色者,母芋芽色为白色类型。 相似文献

分别利用白茎变异甜瓜与正常绿茎甜瓜、黄绿色花冠变异甜瓜与正常金黄色花冠甜瓜进行杂交,得到对应的5个世代,并对各自5个世代中的白茎类型与绿茎类型、黄绿色花冠类型与金黄色花冠类型的分离比例进行分析和卡方检验,以验证理论值与观测值间的关系。结果表明,白茎性状在F1代中不表现,在BC1代中绿茎类型与白茎类型的分离比例为1∶1,而在F2代中二者的分离比例为3∶1;黄绿色花冠性状在5个世代中的表现与白茎性状表现一致。由此可以认定甜瓜白茎性状和黄绿色花冠性状都是由单隐性基因控制的。 相似文献

Floral morphology, random amplified polymorphic DNA (RAPD), and amplified fragment length polymorphism (AFLP) were used to characterize and verify genetic diversity within a white sapote cultivar collection and to develop molecular markers for germplasm identification. On the basis of floral morphology, the cultivars were classified into three types: type I included 23 cultivars with large ovaries and small anthers; type II included 13 cultivars with small ovaries and large anthers; and type III included one cultivar, named ‘Maltby’, with a large ovary and large anthers. DNA was isolated from 39 cultivars of white sapote and subjected to RAPD and AFLP analysis using 24 and 7 primers, respectively. One hundred and sixty-eight RAPD and 286 AFLP bands were used to assess genetic characterization among white sapote. Sixty percent of the RAPD and 77% of the AFLP amplification products were polymorphic among accessions. RAPD or AFLP markers differentiated all white sapote cultivars effectively. Moreover, each flower type was characterized as specially associated with two RAPD bands. UPGMA dendrograms based on RAPD and AFLP data, showed the majority of the cultivars from flower type I and flower type II clustering together. Finally 101 RAPD markers and 220 AFLP markers were used to construct a neighbor-joining dendrogram. This showed that the 37 cultivars could be classified into six distinct clusters, between which the similarity coefficient was as low as 0.00–0.55, even though the cultivars were morphologically very similar. The remaining two cultivars namely ‘Smathers’ and ‘Maltby’ were found genetically very distant from the other cultivars in RAPD, AFLP or combined RAPD and AFLP based dendrograms. The results suggested that the level of genetic variation among white sapote cultivars is diverse and the morphological and molecular data may lead to representation of the cultivar relationships as well as flower type discrimination. 相似文献
