The factors and conditions for increasing disease incidence of barley yellow mosaic virus (BaYMV) by mechanical inoculation were discussed. The results showed that the disease incidence was increased up to 90% or higher as the fresh infected barley leaves or shortly frozen stored ones were used as sources for the inoculation on barley seedlings at incomplete leaf stages under the condition of 18-20℃ temperature and 5000 lx or more for 10-12 hours per day. The results also presented that the thermal inactivation...

The factors and conditions for increasing disease incidence of barley yellow mosaic virus (BaYMV) by mechanical inoculation were discussed. The results showed that the disease incidence was increased up to 90% or higher as the fresh infected barley leaves or shortly frozen stored ones were used as sources for the inoculation on barley seedlings at incomplete leaf stages under the condition of 18-20℃ temperature and 5000 lx or more for 10-12 hours per day. The results also presented that the thermal inactivation point (TIP) (10 min.) was 55-60℃ and the dilution end point (DEP) was 10~(-3) as well as the longevity in vitro (LIV) was about 2 days.

本文探讨了提高大麦黄花叶病毒机械接种发病率有关的条件和因素,试验结果表明以0.1M pH7.0磷酸盐缓冲液(含DIECA)1~5倍量,用新鲜或短期冰冻贮存的病株为接种毒源,接种于不完全叶麦苗,在18~20℃,每天光照(50001x以上)10~12h的条件卜,株发病率可达90%。本方法可试用于大麦品种抗黄花叶病的鉴定。同时用机械接种法测定病毒粗汁液的钝化温度为55~60℃,10min,稀释终点为10~(-3),体外保毒期(20℃)约2天。

The seeds of WA type hybrid rice and its three parents and the conventional rice variety were immersed in the solutions of A (salt substance) and B (acid substance) and cultured under light, the colors of coleoptile and incomplete leaf showed distinct differences resulting from the different pigment metabolism among them, by which the hybrid seed purity of WA type hybrid rice could be tested and identified. Compared with growing identifications both in Hainan and in the locality for two years, the lab...

The seeds of WA type hybrid rice and its three parents and the conventional rice variety were immersed in the solutions of A (salt substance) and B (acid substance) and cultured under light, the colors of coleoptile and incomplete leaf showed distinct differences resulting from the different pigment metabolism among them, by which the hybrid seed purity of WA type hybrid rice could be tested and identified. Compared with growing identifications both in Hainan and in the locality for two years, the lab identification showed a highly positive correlation with the local growing identification (the coefficients 0.935 for Shanyou 63 and 0.900 2 for Xieyou 10), indicating that this method used for testing hybrid rice seed purity has high accuracy and good practicality. It is expected that this method would replace the Hainan growing identification for seed purity in WA type hybrid rice.

通过对野败型杂交水稻及其亲本“三系”和一般常规稻种子在一定浓度的A(盐类化合物)、B(酸类化合物)试剂溶液里进行光照培养,利用其色素代谢差异使幼苗鉴定器官芽鞘和不完全叶表现色泽不同而达到鉴定野败型杂交稻种纯度的目的。通过2a与海南和当地正季生产鉴定相比较,结果显示:用本研究鉴定结果与当地正季生产鉴定结果呈高度相关,相关系数分别为0.9351(汕优63)和0.9002(协优10号),同时,1a多的生产应用亦表现很高的准确性和实用性。该方法能较好地解决现阶段我国野败型杂交稻种纯度室内鉴定问题而替代海南种植鉴定

The leaf cuticle of Cordaites neimengensis sp. nov was studied by light and scanning electron microscopy. The specimens were collected from Lower Permian of Zhungeerqi, Inner Mongolia (Neimenggu), China. Comparing with other species of Cordaites, it was a new species of the genus, based on the structure of its epidermis. Cordaites neimengensis sp. nov (Pls.Ⅰ to Ⅲ; Text-fig.1,B) The specimen comprises two incomplete leaves over 16 cm in length. One is about 1.4 cm wide at the lower part and 0.3 cm wide at the upper part, with nearly 29 veins per cm and 3 to 5 interstitials. The width of the other leaf is about 7.5 cm at the lower part and 8.2 cm at the upper part with 25 veins per cm and 3 to 5 interstitials. Epidermis amphistomatic. Epidermal cells of upper cuticle aligned in longitudinal rows, nearly rectangular in shape, about 33.6 to 86.4 μm×10.2 to 28. 8 μm in size. Stomatal apparatus consisting of 2 sunken guard cells surrounded by 2 lateral and 2 polar subsidiary cells. Stomata haplocheillic, about 56.2 μm×45.5 μm in size, usually arranged in short chains, with one polar subsidiary cell (usually 23.1 to 25.4 μm wide, 34.1 to 39.2 μm long in size) shared with 2 consecutive stomata. The polar subsidiary cells round, oblong or rhomboid in shape. The guard cells reniform or bean shaped, usually 9.7 to 11.6 μm wide, 23.4 to 29.1 μm long in size. Density and index of stomata about 18/mm 2 and 3.2%, respectively. Epidermal cells of lower cuticle also nearly rectangular in shape, about 62.4 to 144 μm×9.6 to 16.8 μm in size. Stomata on the lower cuticle, haplocheillic, 40.8 μm wide and 48 μm long in size, with a pair of sunken guard cells, which is bean shaped and surrounded by 2 lateral and polar subsidiary cells. Stomata arranging in parallel bands, typically one, sometimes two. As for the latter, a single row of lateral subsidiary cells (9.2 to 14.4 μm wide, 33.6 to 62.4 μm long in size) is shared with 2 parallel rows of stomata and occasionally also in bands with two rows side by side. In view outside, small papillae on the outer periclinal wall as well as the lateral subsidiary cells. In view inside, some folds along the anticlinal wall but flat about the periclinal wall. Nonstomatic bands usually with 1 to 10 rectangular cell rows. Density and index of the stomata about 209/mm 2 and 27.2%, respectively. Holotype: 9342; Locality: Heidaigou of Zhungeerqi, Inner Mongolia, North China; Age: Lower Permian (Shanxi Formation).
