The signals look like noncontinuous beads on the DNA fiber,which consist of multi-copy and arrange tandemly.Fiber-FISH results with 45S rDNA probe showed that an average signal length is about 3～11μm in many tandem copy sequence(measure number,n=8),so we estimated the size of each copy to be approximately 11～30kb in cotton genome.There are dual signals on each end of the mitosis metaphase chromosomes and pachytene chromosomes hybridized with telomere DNA probe.The signals also look like non-continuous beads on the DNA fiber,the length is about 1～9μm,so we estimated the size is about 4～27kb.The signals almost covered the whole mitosis metaphase chromosomes and pachytene chromosomes of G.arboretum Shixiya 1 hybridized with gDNA probe,the euchromatin zone and heterochromatin zone were identified clearly on pachytene chromosomes,and the signals also look like non-continuous beads.Two BAC clones 150-D-24 and 182-F-9 in DNA BAC library of Pima90 were selected as probe to hybridize with mitosis metaphase chromosomes,pachytene chromosomes and DNA fiber of G.raimondii.

棉花FISH技术系统的应用研究。45S rDNA在亚洲棉石系亚1号中期和粗线期染色体上有两对大的信号，在DNA纤维上信号为非连续的念珠状，多个拷贝串联排列，每个拷贝长度大约在3～11μm，推测每个拷贝的实际长度为11～30kb；端粒序列在亚洲棉石系亚1号中期和粗线期染色体端部都有双点信号，在DNA纤维上信号也为非连续的念珠状，不同染色体上信号长度大约在1～9μm不等，推测实际长度为4～27kb；gDNA信号几乎布满整个亚洲棉石系亚1号中期和粗线期染色体，在粗线期染色体上能明显区分出常染色质区和异染色质区，DNA纤维上的信号均为非连续的念珠状。

Photosynthetic traits of Ningai 1 and its 4B-monosomic, nullisomic line were investigated in this paper(Rht3 gene was located in 4B-chromosome). 4B-chromosome has the positive effects on photosynthetic rate, chlorophyll content, RuBP carboxy lase content and activity, leaf conductance, chlorophyll relatve steady phase and photosynthetic avtive duartion and these effects are accumlative. So 4B-chromosome has the promoting influence on photosynthesis.

本文系统地研究了带有Rht3基因的4B染色体二体(宁矮1号)、单体(宁矮1号M4B)、缺体(宁矮1号N4B)材料的光合特性，发现带有Rht3基因的4B染色体对光合速率、叶绿素含量、RuBP羧化酶含量及活性、叶片导度均有正效应，并有累加作用，而且对叶绿素含量缓降期和光合速率高值持续期也有正效应，因此带有Rht3基因的4B染色体具有促进光合作用的效应。
