Forty five chemically induced polyploid Hevea plants were obtained from the budwoods of the best clones Hal Ken 3, SCATC 2-14-39 and SCATC 7-18-55. According to cytological identification, the number of chromosome in most somatic cells of these polyploid trees was 2n=45~72. Polyploid cells of each plant account for more than 60% of its total number of divided cells. A series of morphological variations occurred in these plants, for example, the mesophyll and the lateral veins became markedly thicker and the leaves dark green. The 'screening of these trees has been made up to their second or third generation. Of these polyploid trees, the biggest one is about two meters high and has produced several polyploid branches now. When colchicine+kinetin were used as mutagens, most of the first leaf stories from the treated buds were mosaics but almost all the second leaf stories became dipliods (2n=36) again. Therefore, we selected the stems of the first leaf stories with marked polyploidy variations for isolating and screening in the first asexual generation. The mutant buds obtained from this generation represent about 0.1%. It was found that only when these mutant buds continued to be budded up to the second generation for screening, could more polyploid plants be obtained. But in this generation, segregation still occurred because about 30% of normal plants were observed. After cytological identification and selection of good individual polyploid plants from the second generation for further screening, almost all plants obtained from the third generation were polyploids.

本文报道从海垦8,热研2—14—39,热研7—18—65等优良无性系芽条诱导出45株多倍体植株,经细胞学鉴定,这些植株的体细胞染色体数大多为2n=54~72,每个植株的多倍细胞均占其总分裂细胞数的60%以上。这些多倍体植株的外部形态发生了显著的变异,如叶片显著增厚、叶色浓绿、叶脉增粗等。目前这些植株已进入无性系第2代和第3代筛选,其中最大的多倍体植株已高达2米,而且已开始出现多倍分枝。在试验研究过程中,我们发现采用秋水仙碱和激动素等诱导剂时,诱导当代芽条的第一蓬叶大多数属于嵌合体。至第二蓬叶时则几乎全部恢复正常(2n=36)。将当代第一蓬叶的嵌合体茎干进入无性第一代分离筛选时,约产生千分之一的突变芽,只有将这些突变芽继续芽接至第二代筛选时才能获得较多的多倍体植株,但这一代仍然有分离现象。分离出正常的植株约占30%。从无性第二代中再经细胞学鉴定,选出较纯的多倍体植株进行无性第三代筛选时,所获得的第三代植株几乎全部属于多倍体植株。

An investigation of tomato virus diseases in the region of Zheng-zhou was conducted in 1989.The average rate of diseased plants was 36.4%,the highest 50%;the average disease index was 19.4%,the highest 30.Leaf-mosaic was the main symptom,averaging 60.4——streak accounted for16.8% and leaf-narrowing 16.5%.Among the 200 spring tomato samples ex-amined,TMV and CMV infected plants accounted for 44% and 38.5%,PVXinfected plants 3%,complex infection of TMV and CMV 8%.Among the100 autumn tomato samples examined TMV and CMV infected plants account-ed for 28% and 40%,complex infection of TMV and CMV 28%.Pathogens in-ducing 3 main symptoms of spring and autumn tomato were different.Mosa-ic type was caused mostly by TMV accounting for 47.2% and CMV 44% andcomplex infection of TMV and CMV 4.4%.Leaf-narrowing type was causedmostly by CMV alone accounting for 63.2%;streak caused by complex infect-ion of TMV and CMV amounted to 50%.

1989年在郑州郊区对番茄病毒病进行了调查,平均病株率为36.4%,最高达50%以上,平均病情指数为19.4,最高达30以上。症状以花叶为主,占60.4%,条斑和蕨叶并重,分别占16.8%和16.5%,其它症状占6.3%。毒源种类鉴定结果表明,春番茄上主要毒源种类是TMV、CMV,分别占46.5%和38.0%;其次为二者复合侵染,占8.0%;还有PVX,占3.0%;未检出病毒的样品占6.5%。秋番茄主要毒源为CMV,占40.0%;其次为TMV 和TMV 与CMV 复合侵染,二者均占28.0%,未检出病毒的样品占4.0%。引起番茄3种主要症状的病毒种类不同,花叶型主要由TMV 或CMV 单独侵染,分别占47.2%和44.0%。蕨叶型主要由CMV 单独侵染,占63.2%。条斑型主要由TMV 和CMV 复合侵染,占50.0%,TMV 单独侵染占32.8%。

There are 6, 000 species of higher plant in Guizhou, or which 4,950 species (varieties) are seed plants, there are many species of ancient endemic and solitary plants in Guizhou, and 280 species (varieties) ofendcmic plants belong to 66 families and 144 genus. The endemic plants account for 33.8% of all families, 10.3%of all genus. And there are 31 endemic monotypic genera of single type, 4 endemic monotypic genera of single species of China distributed there, which arc: Tengia,...

There are 6, 000 species of higher plant in Guizhou, or which 4,950 species (varieties) are seed plants, there are many species of ancient endemic and solitary plants in Guizhou, and 280 species (varieties) ofendcmic plants belong to 66 families and 144 genus. The endemic plants account for 33.8% of all families, 10.3%of all genus. And there are 31 endemic monotypic genera of single type, 4 endemic monotypic genera of single species of China distributed there, which arc: Tengia, Thamnocharia, Centratheropsis and Dicercoclados.Because of the narrow distribution and the deterioration of environment, most of the endemic plants in Guizhou arc threatened to be extinct. 15 species' germ plasm conservation has been studied for 3 years, which focus on: 1, soil and humidity control, culture and time of introduction; 2, imitation of original environments ccocomm unities; 3, these endemic plants original from ancient incomplete plant, or original from plant development and evolution in original environments, This experiment supports the argument point of << Plant Toxonomy and Biosys Tematics>> by Clive A. Stace.

目前贵州特有或仅在贵州分布的种子植物共计280种(含变种),占贵州省种子植物总数的5.3%.它们分别隶属66科、144属.贵州特有植物,分布范围狭窄,环境恶化,它们不仅稀少,而且濒危.为此,三年来,我们择其具有显著代表性和开发应用前景较好的15种植物进行种质资源的保存研究工作.
