试论我国彩色棉的发展 总被引:8,自引:0,他引:8
本文就彩色棉的特点,利用常规育种技术改良彩色棉纤维品质遇到的一些难题,如绿色棉纤维中含蜡质量大因而影响强度及遇光产生变色的问题;棕色棉纤维的色彩度与品质性状呈负相关连锁遗传等问题,提出了解决这些问题的方法应依赖于基因克隆技术。同时,对如何发展我国的彩色棉生产提出了几点建议。 相似文献

彩色杂种棉经济性状优势表达规律初步分析 总被引:1,自引:0,他引:1
本文研究表明,彩色杂种棉具有以下优势表现特征:1)在植株与棉铃性状方面,彩色杂种棉的单铃重、每囊粒数、籽指皆具有比较明显的杂种优势;衣分与衣指多具有正向中亲优势,但竞争优势皆为负值。2)在产量上,彩色杂种棉产量多具有明显的杂种优势,而皮棉产量多表现负向杂种优势。但通过优选亲本、合理配组,仍可以筛选出在皮棉产量上具有优势的组合。另外,彩色杂种棉霜前花中亲优势与竞争优势皆为正值,表明彩色杂种的棉的早熟性的普遍较好。3)在纤维品质方面,彩色染种棉的纤维长度、纤维比强度具有明显的正向中亲优势,但竞争优势取决于配组亲本的品质水平。马克隆值中亲优势的表现没有明显规律,但马克隆值的竞争优势皆为负值,即与当前推广品种相比,彩色杂种棉的马克隆值相对较低,纤维相对较细。文章最后建议,在亲本选配上最好选择比强度在25cN/tex以上、绒长在31mm以上的高品质白色棉作为配组的杂交亲本,这样容易选育出在品质上具有竞争优势的彩色杂种棉组合。 相似文献

This study was done to propose color conditions and fabrics that satisfy the particular sensibilities of consumers and producers through an analysis of color sensibility factors for an environmentally-friendly material, i.e., naturally colored organic cotton (NaCOC) fabrics. Toward that end, the colorimetric properties of eight NaCOC fabrics were measured, and the fabrics?? subjective color sensibilities were evaluated. In addition, based on the relationship between the colorimetric properties and subjective color sensibilities, the prediction models for color sensibilities of NaCOC fabrics were developed. According to the established models, hard-soft, cool-warm, deep-pale, vague-distinct, plain-showy, and subdued-vivid sensibilities can be predicted by some variables of colorimetric properties such as L*, a*, C*, and h. As another ultimate goal of this study, suitable NaCOC fabrics to evoke certain sensibilities were proposed by multidimensional scaling method. The proposed fabrics and color sensibility factors are believed to offer an important guideline for those who design clothing products made of NaCOC. 相似文献

Color filters were prepared by using azo colorants and nitroso metal complex colorants. Initially, crushed glass particles were colored by using the azo and nitroso-iron complex colorants. These colored glass particles were used to obtain a colored composite with unsaturated polyester resin to give colored glass filters. Glass filters obtained were used for study to evaluate fading rate with respect to UV radiation, heat and moisture. Thermo gravimetric analyses of synthesized colorants were also carried out to determine their thermal stability. 相似文献

Colored rice is beautiful and edible. It can provide a new way for merging agriculture, tourism, education and culture together. Breeding and studying edible and ornamental colored rice can promote the combination of agriculture and tourism and the development of creative agriculture. In this paper, we summarized the germplasm improvement, major types, mutation mechanism, representative utilization of colored rice, and proposed the possible development trends of the colored rice in the future. 相似文献

为探讨适宜长江流域棉区棉田间作栽培的模式,以增加棉花产量、改善纤维品质和获得更高的经济效益。比较了棉花间作大豆、棉花间作玉米和棉花间作甘薯三种模式的经济效益、棉花产量、纤维品质、干物质积累及叶面积指数的变化特点。结果表明:三种间作模式较单作棉花可增加纯收入,棉花产量和干物质积累量及单位面积成铃数均增加;马克隆值变优和断裂比强度提高;在棉花盛蕾期棉花叶面积指数三种模式均比对照提高,在棉花盛铃期及以后的棉花叶面积指数因模式不同而有差别。棉花间作甘薯和棉花间作大豆模式的籽棉产量较高、经济效益好,纤维品质较优,其生产优势较为明显,适宜在长江流域棉区推广。 相似文献
