A filamentous virus, with particles 600-650?nm long, was purified from Narcissus pseudonarcissus (daffodil) in Hangzhou and an antiserum prepared.
      
These results therefore suggest that the Hangzhou isolate should be regarded as a new member of the genus Potyvirus, and we have tentatively named it Tuberose mild mottle virus.
      
Tuberose plants with mild mottle symptoms, growing in a glasshouse in Hangzhou, China, contained virions and inclusion bodies typical of a potyvirus.

Based on a fishery-biological survey of the Yao-Jiang River, ZheJiang Province, carried out during 1976-1977, the writer delineates the ecological properties of fish population and estimates the fish-producing capacity of this river.With the construction of dams across the River, the latter takes up some characteristics of a reservoir. The new environmental condition, especially the richness of plankton, is favorable to the development of freshwater fishery.There are 58 species of fish in the Yao-jiang River, with species composition similar to that of the lakes along the lower reaches of the Chang Jiang River. Owing to the practice of stocking, the fish community in the River is now a semi-artificial one. Population of bighead, silver carp, grass carp, black carp and blunt-snout bream are formed by artificial stocking; while common carp, crucian carp, Erythroculter dabryi, Acanthobrama simoni, Salangidae, Coilia ectencs, etc. represent the natural population. There is no serious interspecific competition, and these species are mainly supplementary in their interaction with reference to the utilization of spatial and temporal dimensions and food resources of the water body.The annual fish yield of the River from 1971 to 1976 averages 48.1 jin per mu, of which 65% are stocked species, 35% are natural population. And among the stocked species, bighead and silver carp constitute an overwhelming part. By making comparisons on the food resources, the growth rate and the population structure of fishes between the Yao-jiang River and the Qing-shan Reservoir in Hangzhou, Zhejiang Province as well as the Dong-hu Lake in Wuhan, Hubei Province, the writer points out that: (1) The plankton resources in the Yao-jiang River have not been fully utilized, and the stocking rate of silver carp should be higher than in the Tung-hu Lake and not less than that of the Qing-shan Reservoir, then the annual yield of silver carp and bighead put together would increase from the present 30.3 jin to over 60 jin per mu. (2) The food resources of grass carp, blunt-snout bream and black carp still remain to be brought into fuller utilization, but the potentiality of increasing the yield of these consumers seems rather limited. (3) The yield of natural fish stock such as the common carp, crucian carp, etc. has been more or less steady in recent years, and if due attention is paid to protective measures and to the natural proliferation of the stock, their production in the River may rise to a higher level. Accordingly, by rational stocking, by fuller utilization of food organisms as well as by protection of the natural fish stock, coupled with the improvements of fish screen installations, the yearly fish yield of the Yao-jiang River should in all likelihood reach the level of 80 jin per mu or so (around 600kg per hectare).

A new neutral proteinase-producing strain 0031 has been selected from the air of Hangzhou Leather Plant.In primary observation of the cultural property of the strain 0031,we had found that it was more resemble to Bac. subtilis(A.S.1398),but the enzymogram of fermentative liquor after disc electrophoresis was different from Bac.subtilis (A.S.1398).

A new neutral proteinase-producing strain 0031 has been selected from the air of Hangzhou Leather Plant.In primary observation of the cultural property of the strain 0031,we had found that it was more resemble to Bac. subtilis(A.S.1398),but the enzymogram of fermentative liquor after disc electrophoresis was different from Bac.subtilis (A.S.1398). The adequate cultural conditions for the strain have been established: composition of the liquid medium(%)is:soya bean 3%,corn flocer 2%,wheat bran 3%,KH_2PO_4 0.03%,Na_2HPO_4 0.4%,pH 8.0(before sterilization).After fermentation in shaking flasks(50ml/500ml/Δ,220 r.p. m.,ecc.dis.2.5cm.), at 28℃,for 38 hrs,the caseiaolytie activity was stablized at about 2000μg/ml, and the maximal activity could reach 2330μg/ml. During the process of study on the properties of enzyme-producing,we have found:1.suitable increase of aeration rate and pH,which will increase the enzymic produce and shorten the fermentative cycle;2.a tendency to slightly repress the enzymic produce and delay the enzymic peak,if fermentative temperature is above 30℃.3.no action of Zn■ and Ca■ on enzymic produce(test concen- tration ZnSO_4 0.005%,CaCl_2 0.3%).

我们从9株水解圈比值(水解圈直径/菌落直径)较大的(一般在7以上)初筛株中,经摇瓶复筛,筛选出一株中性蛋白酶产生菌0031菌株.经初步观察其培养特征较接近于枯草芽孢杆菌(A.S.1398),但其发酵液在盘状电泳上的酶谱,有别于枯草芽孢杆菌,其产酶的摇瓶发酵培养基为:豆饼粉3%,玉米粉2%,麸皮3%,KH_2PO_40.03%,Na_2HPO_40.4%,pH 8.0(消毒前).在50 ml(每500 ml 三角烧瓶)的装量,旋转式摇床(转速220次/分偏距2.5cm)温度28℃的条件下发酵,经34—38小时,酶效价稳定在2000单位左右(测定反应温度30℃)最高效价可达2330单位.在该菌株的产酶特性的探索过程中,我们发现1.适当的加大通气量和提高 pH 能提高产酶量和缩短发酵周期,但美中不足的是酶高峰期较短促,较不利于在发酵过程中控制产酶高峰点.2.提高发酵温度(30℃以上)略有抑制产酶的趋势或有明显的酶高峰期推迟的现象.3.Zn~艹和 Ca~艹(试验浓度分别为 ZnSO_40.005%和 CaCl_2 0.3%)对产酶无促进作用.根据目前所表现的生产性能,0031筛选株是理想的,值得联系实际目的,进一步研...

The present paper is the experimental results of our preliminary study on the aseptic culture and tissue culture of Arabidopsis thaliana (L.) Heynh. collected from Hangzhou. Flowering response of this plant was studied under different photoperiod treatments. T c results obtained show that with the culture temperature maintained at 25±1℃, continuously illuminated by about 4000 Lux. intensity from white fluorescent light tubes,the plant took about 19 days from germination to flowering in test tube, but, at the same light intensity under 12 hrs. photoperiods daily, it required about 32 days. Statistical data indicate that the average of seeds obtained from the plants in the former case was 73.07±42.67, but up to 150.00±42.67 in the latter. At the same time, we excised stem segments, petioles (length about 2mm) and leaf pieces (size about 4×4mm~2) of the aseptic plants as material for tissue culture. It was observed that calluses were induced from all the above mentioned three explants, in the culture medium B_5 and MS containing 2,4-D (0.5—5.0mg/L) or NAA (1.0—8.0mg/L) combined with KT (6-Furfuryl aminopurine, 0.2 or 0.5 mg/L). Entire plants were regenerated from all the three calluses. Also discussed in this paper are the improvements made on cultural techniques.

我们对拟南芥菜无菌培养的条件作了初步研究。在培养过程中,对它的光周期反应进行试验,观察到它在25±1℃和光强度约4000勒克斯白色熒光连续光照的培养条件下,平均可在19天内开花;而以同样光强度,12小时光照/12小时黑暗交替处理时,则需要32天才能开花。据统计,经前法处理的植株,平均每株结实73.07±42.67粒,而后者则达150.00±42.67粒。同时,我们曾切取了无菌培养植株的茎段、叶柄和叶片进行组织培养,发现上述三种组织的外植体均能在附加2,4-D(0.5—5.0毫克/升)或NAA(1.0—8.0毫克/升)与KT(6-糠基氨基嘌吟,0.2或0.5毫克/升)的B_5和MS培养基上诱导出愈伤组织;并分別从它们分化出完整的再生植株。
