苎麻组织培养研究进展 总被引:1,自引:0,他引:1
组织培养是保存苎麻种质资源、进行快速繁殖的有效方法,并且是运用基因工程技术改良苎麻品质的重要手段。近年来国内研究学者开展了苎麻组织培养研究,本论文从不同基因型、不同的外植体、不同基本培养基、不同的激素对苎麻增殖与分化的影响,以及培养条件等方面综述了近年来在苎麻组织培养方面的研究进展。 相似文献

用组织培养的方法对植物进行无性繁殖已在许多种植物上获得了成功。苎麻腋芽培养与繁殖具有较高的繁殖系数,芽形成根的时间短,而且移栽的成功率较高。因此对苎麻腋芽培养繁殖具有较大的实用价值,并巳具备工业化生产的条件。目前用于苎麻培养的培养基包含有售价较高的琼脂、 相似文献

苎麻属野生种光温特性研究初报 总被引:3,自引:0,他引:3
对苎麻属野生种17个种进行了不同光照长度、不同播种期的试验研究.结果表明,不同的野生苎麻种对光照长短的敏感性有所不同,长光照和短光照均对野生苎麻的现蕾开花有较大的影响,在不同光长条件下,由于野生苎麻种不同表现出不同的光反应类型.温度对生长发育有一定影响,随着播种期推迟,现蕾、开花所需的积温减少. 相似文献

基于苎麻属野生近缘种形态变异类型的系统关系研究 总被引:1,自引:0,他引:1
本文从变异性分析、相关分析和构建系统聚类树方面系统地研究了苎麻属野生近缘种5组26种(变种)的基本形态生物学特征。结果表明:1)苎麻、大叶苎麻、序叶苎麻、细野麻这4个野生种形态的丰富变化主要集中在叶色、叶脉色、托叶色、叶缘锯齿这几种表型。2)苎麻属各野生种表型之间叶形与叶基特性的关系非常紧密,其余的形态表型之间没有发现显著的相关。3)苎麻组组内演化关系为微绿苎麻→青叶苎麻→苎麻、贴毛苎麻。苎麻和贴毛苎麻都起源于青叶苎麻。4)苎麻属野生种种间的系统聚类树显示,处在最低位置的苎麻属组群是帚序苎麻组和腋球苎麻组,序叶苎麻组位于中间位置,苎麻组和大叶苎麻组则是位于最高位置的苎麻属组群,苎麻组和大叶苎麻组的亲缘关系更加紧密。该研究结果对进一步研究苎麻属野生近缘种分类及系统演化提供了基础。 相似文献

秦岭、大别山地区野生苎麻开发利用考察 总被引:1,自引:0,他引:1
秦岭、大别山一带野生苎麻十分丰富,本世纪60~70年代,这里的野生苎麻干皮大量调往大兴安岭、小兴安岭一带,做吊运木材的绳索用,每公斤干皮仅0.4元,利用价值很低。近几年少数地方利用野生苎麻干皮制成了与栽培苎麻类似的精干麻,每公斤干皮价值6元左右,经济效益显著提高,为了详细了解野生苎麻的分布和利用,我们于1984年9月至11月, 相似文献

用组织培养法繁殖野生亚麻的研究 总被引:7,自引:1,他引:7
野生亚麻是优异的种质资源,由于其种子具有较强的休眠性,用常规方法繁殖难度较大,本试验利用组织培养方法,通过对实生苗幼嫩的茎杆及叶片诱导愈伤组织再分化苗的途径,对野生亚麻的试管苗扩繁进行了研究,获得了一定数量的野生亚麻再生无根苗。研究结果表明,野生亚麻愈伤分化成苗对培养基的选择性不强,用组织培养法快速繁殖是行之有效的途径。 相似文献

AbstractWaterlogging Stress is An Important Limiting Factor For Wheat and Barley Production. Waterlogging Tolerance Was Evaluated in The Seedlings of Seven Species From The Tribe Triticeae, including Wheat, Barley, Durum Wheat, Rye (Diploid and Tetraploid), Triticale, Einkorn Wheat, and Mizutakamoji (Agropyron Humidum), To Acquire Basic information About Their Variation in Waterlogging Tolerance and To Elucidate Opportunities For Genetic Improvement of Waterlogging Tolerance in Cultivated Wheat and Barley. The Seedlings At The One Leaf Stage Were Subjected To Waterlogging For 0 (Control: Ct) Or 12 Days (Waterlogging: Wt) in Plastic Cups (12 Cm Tall, 8 Cm in Diameter), and The Morphological Traits of Shoots and Roots Were Measured. Shoot Dry Weights (Dw) of Wheat (Cv. Norin 61) and Barley (Cv. Benkeimugi) Were Lower Under Wt By 73% and 59%, Respectively, Than Those in Ct. of All The Evaluated Genotypes, Only A. Humidum SHowed No Reduction in Shoot Dw Under Wt. The Relative Shoot Dw (W/C in Shoot Dw; Proportion of Shoot Dw in Wt To That in Ct) Was Significantly Correlated With Relative Root Dw (W/C in Root Dw). The W/C in Root Dw Correlated Significantly With W/C in The Number and Length of Adventitious Roots, and With W/C in Frequency of Branching Roots On The Seminal Root, Suggesting That Development of Adventitious Roots and Branching Roots Under Wt Might Be Related To Waterlogging Tolerance in Tribe Triticeae. The Results of This Study indicated That Wild Species of Tribe Triticeae, Such As A. Humidum, Might Be Useful Resources To Analyze Waterlogging Tolerance in Cultivated Wheat and Barley. 相似文献

Explant culture has been used for crop improvement, providing a rapid method for regeneration of desired genotypes. The four explants of anther, young panicle, young embryo and mature embryo have being studied more in rice tissue culture and the culture response of them could affect breeding [1–7]. The present study was aimed to find out whether there are correlations among the culture responses of different types of explants in the same genotype. If the hypothesis were true, then it was like… 相似文献
