     Thus, overexpression of the Nr gene was caused by environmental stress related to ABA. This stress induced the biosynthesis of inner ethylene, which is the main reason of leaf chlorosis and plants senescence.
     因此,M基因的大量表达是由于ABA等环境胁迫诱导了内源乙烯的大量合成,是导致植物黄化和衰老的主要原因之一。

  plant etiolation
Stock plant etiolation and stem banding effect on the auxin dose-response of rooting in stem cuttings of Carpinus betulus L.
      
Experiments were undertaken to determine the effect of stock plant etiolation and stem banding, prior to cutting propagation, on the auxin dose-response of rooting in Carpinus betulus L.
      
Stock-plant etiolation causes drifts in total soluble sugars and anthraquinones, and promotes adventitious root formation in tea
      
The effects of stock-plant etiolation on coppice-shoot growth, drifts in total soluble sugars and anthraquinones (AQs; C14H8O2), and rooting potentiality of shoot cuttings were examined in Tectona grandis L.
      
Stock-plant etiolation caused a significant increase in percent rooting and sprouting, shoot length, number of shoots and number of leaves per SNC, but a decrease in callusing at the base of the SNC.

In Hainan Island of Guangdong Province,a yellow type diseaseoccurred on Desmodium ovalifolium Wall,Stylosanthes gracilis H.B.K,Phaseolus atropurpureus W.Siratro,and Glycine javanica D.The diseasedplant exhibited severe stunting,excessive proliferation of shoots and theformation of witches' broom.Electron microscopic observations of theultrathin sections of the phloem tissue from the infected leaf vein revea-led mycoplasma-like organisms(MLOS)in the sieve tubes.The pleo-morplic MLO were around 170-800 nm(Stylosanthes...

In Hainan Island of Guangdong Province,a yellow type diseaseoccurred on Desmodium ovalifolium Wall,Stylosanthes gracilis H.B.K,Phaseolus atropurpureus W.Siratro,and Glycine javanica D.The diseasedplant exhibited severe stunting,excessive proliferation of shoots and theformation of witches' broom.Electron microscopic observations of theultrathin sections of the phloem tissue from the infected leaf vein revea-led mycoplasma-like organisms(MLOS)in the sieve tubes.The pleo-morplic MLO were around 170-800 nm(Stylosanthes gracilis H.B.K),170-700 nm(Desmodium ovalifolium Wall),250-650 nm(Phaselus atropu-rpureus W.Siratro),and 375-770 nm(Glycine javanica L.),some withnucleic acid strands and some apparently undergoing binary fission orbudding。Since these MLO were found in diseased plants but not in healthycontrols,the causal agents of the witches' broom diseases of these greenmanure crops may be mycoplasma-like organisms in nature.

在广东省海南岛发现几种绿肥植物:巴西苜蓿、卵叶山蚂蝗、暗紫莱豆、爪哇大豆罹患了植物黄化病害。病株表现症状:植株矮化、枝叶丛生、叶变小、普遍退绿或黄化。电子显微镜观察发现,在病株叶柄韧皮部筛管细胞超薄切片中,存在大量的类菌原体(MLO)。这些菌体形态多样,有些可见菌体内纤维状样核酸物质,有的菌体正处于二分裂、或发芽状态。这些MLO 大小分别为170~800nm、170~700nm、250~650nm、375~770nm。由于在病株中发现有MLO 存在,而健株中则没有。可以初步认为四种绿肥植物丛枝病是由MLO所致。

A virus disease of asparagus bean characterized by a dwarfing ofplant and curling or rugosity of leaves,has been found in Nanjing areain 1983.The isolate C-7 of this virus was transmitted by three speciesof aphids,efficiently by Aphis craccivora and less efficiently by Aphisgossypii and Myzus persicae in the persistent manner,but not by Aphisglycine.The C-7 isolate was not transmitted by sap inoculation.Of 28species of plant in 4 families which were inoculated by the aphids(A.craccivora),15 leguminous species...

A virus disease of asparagus bean characterized by a dwarfing ofplant and curling or rugosity of leaves,has been found in Nanjing areain 1983.The isolate C-7 of this virus was transmitted by three speciesof aphids,efficiently by Aphis craccivora and less efficiently by Aphisgossypii and Myzus persicae in the persistent manner,but not by Aphisglycine.The C-7 isolate was not transmitted by sap inoculation.Of 28species of plant in 4 families which were inoculated by the aphids(A.craccivora),15 leguminous species and 1 solanaceous species were foundto be infected with the virus.The aphid was able to acquire the virusby feeding on the infected asparagus bean plant for at least 3 hoursand the inoculation feeding period was at least 10 minutes.The latentperiod in the aphid vector was 24-36 hours.In serial transmission tests,individual aphids seemed to transmit the virus as long as they livedand retained their infectivity through molting,although not everyplant in a series was infected.Based on symptoms,host range and vec-tor transmission,the virus can be considered as a persistent aphid-tran-smitted virus belonging to the group of Luteoviruses.

1983年6月,在南京郊区的长豇豆上采到1株表现植株矮缩症状的C-7病毒分离物。接种试验证明,它不能摩擦接种传病,但可以由豆蚜(Aphis crac-civora)、棉蚜(A.gossypii)和桃蚜(Myzus persicae)以持久性方式传病。寄主范围测定的结果表明:分离物可以侵染长豇豆、豇豆、蚕豆、大豆、菜豆、豌豆、赤豆、利马豆、苜蓿、红三叶、地三叶、绛三叶、葫芦巴,紫云英和苕子等15种豆科植物和曼陀罗1种茄科植物。这些植物大都出现植株矮化,叶片扭曲,卷缩或僵缩,不能开花结实等症状。豆蚜的传病性状中,获毒饲育的最短传病时间为3小时,接毒饲育最短传病时间为10分钟,循回期是24小时左右。但是,传病率最高的获毒饲育时间是2~3天,接毒饲育时间在1天以上。接种1头蚜虫就具有传病能力,5头蚜虫能达到100%的传病率。蚜虫可以终身传毒,蜕皮不影响其传毒力,但传毒有间歇性。根据它的基本性状,病毒C-7分离物是一种豆科植物的黄化型病毒,可能是属于大麦黄矮病毒组(Luteovirus Group)的成员。

The analysis shows that Lüheng tiewang can raise the chlorophyll content in leaves and has obvious function on reducing the yellowing disease.There is no relationship between the contents of Te,Zn and chlorophyll in leaves.Te,Zn are not main factors that cause yellows.

通过对绿亨铁王防治香樟黄化病的药效试验分析 ,证明该药能够使香樟叶绿素含量提高 ,对缓解香樟黄化有明显的作用 ,叶子中 Fe、 Zn含量与叶绿素含量之间不存在相关关系 ,Fe、 Zn不是引起植物黄化的主要因素
