Some physical properties of rice bunchy stunt virus(RBSV)were studied by injecting the extracts of iseased rice plants after various treat-ments into healthy Nephotettix cincticeps.Results showed that the ther-mal eath point of RBSV in plant extracts was between 60 and 70℃ for10 minutes.The dilution end point was between 10~-) and 10~(-5) in diseasedrice plant sap,and between 10~(-3) and 10~(-4) in viruliferous insect extract.The longevity in itro was 4~5 days at 4℃ or 2~3 days at 22℃.The infectivity of RBSV in extracts from diseased rice leaves was hehighest(25.0%),that from sheaths the second(10.5%);that from rootsystem was the lowest(4.8%);while that from tems couldn′t bedetected.The circulation period of the injected virus in insect vectorswas 7~17 days,the average as 10.3 days.It was shorter than that bycommon acquisition feeding method.The infectivity of RBSV could bedetected 5 days and above after acquisition feeding and the highest in-fectivity was at 25 days after feeding.The incubation eriods of thedisease in rice plants were 8~22 days at 27℃,most of them were13~14 days.

以水稻簇矮病株或带毒昆虫的榨出液,注射于Nephotettix cincticeps体内,依其日后对稻苗的侵染力,测得水稻簇矮病毒(RBSV)的致死温度为60~70℃,稀释限点为10~(-4)~10~(-5)(病叶榨出液)或10~(-3)~10~(-4)(带毒虫榨出液),体外存活期为4~5天(在4℃下)或2~3天(在22℃下)。RBSV在病株中以叶片汁液的侵染力最强(感染率为25.0%),叶鞘次之(10.5%),根系最低(4.8%),茎秆未能测出。病毒注射虫体后的循回期在26.9℃下为7~17天,平均10.3天,比常规饲毒的要短。病毒在虫体内自饲毒后需10天以上才能测出侵染力,但以25天的最强。病害的潜育期(在27℃下)为8~22天,一般多在13~14天。病毒接种后在稻株体内10天即具侵染力,但以30天的最强。

A HPLC separation and determination of sarmentosine in the plant and its preparations is reported. The method is proceeded with reverse phase chromatographic system using ODS column in series with amino bonded precolumn to separate sarmentosine from the major interfering parts. The mobile phase used is methanol acetonitrile-water(2:6:100) and the active component is detected with UV detector at λ 225 nm.

A HPLC separation and determination of sarmentosine in the plant and its preparations is reported. The method is proceeded with reverse phase chromatographic system using ODS column in series with amino bonded precolumn to separate sarmentosine from the major interfering parts. The mobile phase used is methanol acetonitrile-water(2:6:100) and the active component is detected with UV detector at λ 225 nm. A procedure of directly introducing the tissue extract into the chromatographic system has been proposed which is intended to be used as a quick analytical method to meet the requirements in investigating plant resource distribution. The method is suitable for the determination of sarmentosine in fresh plant extracts, crude drugs and various medical preparations. The relationship between the sarmentosine content and the variations in growing district, species and its collecting time has been reported. The method can also be used in quality control during processing. It is also possible to study the reason of inconstancy of clinical effects in medical preparations.

本文报告了ODS串连键合氨基预柱,以甲醇—乙腈—水(2∶6∶100)为流动相和UVλ225nm检测,分离测定垂盆草甙的反相HPLC方法。为适于植物资源的快速分析,提出了组织液直按进样法。本法可用于垂盆草的新鲜植物、生药及各种制剂中垂盆草甙的定量分折。根据各种样品的测定结果,考察了垂盆草的产地、品种及采收期与垂盆草甙含量的相关性,探索了制剂工艺条件对质量的影响。

Chlorotic type of narcissus leaf spot in Zhangzhou was observed by the author three years ago.Careful investigations revealed that this malady was very similar to the narcissus mosaic reported abroad regarding morpho- logical characteristics of the virus,the resistance to disease leaf extracts, hosts,and modes of disease transmission. The virus was transmitted by infected bulbs as well as sap inoculation. The NMV plant extract isolate showed thermal inactivation between 55-60℃ for 10 minutes.The virus longevity in vitro culture was 8-10 weeks.The dilution end point was over 10~(-7).Particles of the pathogenic virus appeared as flexuous rods,measuring 470-550×12-13nm,scattering in the cytoplasms of the hosts.

1981年在福建漳州的水仙田中查到一种褪绿斑病株,经研究证实,其传播途径、鉴别寄主、体外抗性和病原形态等,均与国外有关水仙花叶病毒的报道基本一致。病毒以机械和鳞茎种球的方式传播。病毒致死温度55~60℃,体外存活期8~10周,稀释限点10~(-7)以上。病原病毒为线状质粒,大小为470~550×12~13nm,分散在细胞质内。
