本论文针对荷兰引进的四个系列六个品种的郁金香进行促成栽培.对温室、大棚、露地等不同栽培设施,箱栽、盆栽、地栽等不同栽培方式,以及泥炭、土壤等不同栽培基质进行了比较,同时采用多效唑、B9、清水对照进行矮化对比.主要结果:1)温度对郁金香植株生长速度影响大,根系发育后郁金香从栽种到开花所需时间与温度存在明显的相关关系, 20-30℃温室栽培开花需32-46天、大棚地栽开花需51-63天,露地栽培需109-117天.2)以温室栽培为模板、以株高为指标的方法,能大致预测郁金香促成栽培的开花日期.3)采用多效唑200mol/L对于矮化郁金香植株、缩短花梗高有显著效果.4)在江西南昌地区室内自然放置的郁金香种球能正常完成花芽分化,截至9月初,南昌地区的郁金香种球的雌蕊分化完成.

用多效唑(PP333)和矮壮素(CCC)对三年生盆栽百子莲(Agapanthus praecox Big Blue)进行单处理和混合处理,研究其对百子莲花葶的矮化效应.结果表明:(1) 600mg/L PP333处理的花葶最矮,其花葶长度比CK缩短了70.2％,其次是400mg/L PP333+800mg/L CCC处理和400mg/L PP333处理,矮壮素单处理对百子莲花葶的矮化作用较弱.(2
本研究应用新一代高通量测序技术Illumina HiseqTM 2000对百合索邦的根、鳞片、茎皮、叶、花瓣、柱头六组织等量混合样进行测序,并结合Trinity软件进行无参转录组重头拼接,最终获得了49,991条表达序列标签,其平均长度为673 bp.通过与NCBI公共数据库中非冗余蛋白数据库、Swiss-Prot蛋白数据库、京东基因与基因组百科全书数据库以及直系同源蛋白数据库的联配与比较,全部表
超低温保存(-196℃)是植物种质资源保存最安全经济的技术,本研究初步建立了崇明水仙的超低温保存流程:(1)取崇明水仙的3～4年生鳞茎,用70％酒精消毒1min,0.1％的升汞消毒15 min,无菌水冲洗若干次后,将带3～4层鳞片及部分茎盘的鳞茎切块接种于含BA及NAA的MS培养基上诱导出小鳞茎;(2)将继代3个月崇明水仙的鳞茎诱导后,切取2～3 mm大小的茎尖,(3)接种到含0.3 mol·L-
为了获得无花粉、重瓣百合新种质,利用RT-PCR方法,从百合西伯利亚中克隆得到长888bp的百合花发育AG同源基因LAG,构建了LAG基因的植物过表达载体.测序结果经BLAST分析表明,与麝香百合、玉簪、油棕、龙舌兰、风信子等的AG同源基因同源性较高,分别为95％、81％、81％、79％、78％.LAG蛋白序列与多种单子叶植物的AG类蛋白同源性较高.核酸序列分析和蛋白序列分析都证明了该基因为百合A
