The results showed that the seed germination and stem apexes growth of the materials was decreased with the increase of NaCl concentration and PYM concentration and treating time.
结果表明:供试种子的萌发率和茎端组织的存活率随培养基中NaCl浓度的上升急剧下降,平阳霉素处理对茎端组织存活率的抑制明显大于对种子萌发率的影响,平阳霉素处理后存活的种子和茎端组织经NaCl胁迫筛选,筛选出耐NaCl胁迫力明显提高的存活苗,存活苗经无性繁殖,可以保持较高的耐NaCl能力。

In term of analysis and comparison of differences on ornamental plants among UPOV 1991 and 1978 Convention, and Chinese Regulation on PVP, this paper focus on the specialty of PVP for asexual fruit crops and ornamental plants, and feasibility and advantage of UPOV 1991 Convention to them, such as essentially derived variety and farmers' privilege. Meanwhile, based on present situation of flower Industry development, breeding and creation, and world trade of floricultural crops, the author points out the opportunity and challenge of flower Industry development in China, and proposes a strategy of IPR and PVP on Chinese flower industry.
本文在分析对比 UPOV 公约1991年、1978年文本和我国《植物新品种保护条例》的主要区别及其在观赏植物适用方面存在诸多差异的基础上,重点探讨了无性繁殖花卉和果树类植物新品种保护的特点以及 UPOV 公约1991年文本对这些特点进行的适用性修改与完善,主要表现在实质性派生品种和农民豁免权方面;结合我国的观赏植物育种、花卉产业发展与花卉国际贸易现状,详细解析了知识产权战略与新品种保护制度给花卉业发展带来的机遇与挑战;在此条件下,提出我们自己的应对策略。

The extensive variation in chromosome number in root tip cells of three Chinese cabbage-cabbage monosomic alien addition lines with 21 chromosomes, 6-2-4, c-2-4 and d6, was obsevered after vegetative propagation multi-generations. The chromosome number varied from 17 to more than 50. The 25S rDNA signals were very complex in the three different clones.
染色体数目为21条的3个大白菜-结球甘蓝单体异附加系6-2-4、c-2-4和d6,在无性繁殖多代后根尖细胞均出现了广泛的染色体数目变异的现象,变异范围从17条到50多条不等,25S rDNA在这些无性系的FISH杂交信号较为复杂。

Unfortunately, I was unable to view the pictures in the attachment in your e-mail, but I assume that you are referring to the recent dog culls in China where over 50,000 dogs were slaughtered in an attempt at rabies control.
谢谢你和世界动物保护协会联系,并关注中国的动物福利问题,我们已经知道在中国约50,000只狗被因为狂犬病的控制问题被屠杀的事情,世界各地的动物福利组织非常的震惊和愤怒,世界各地的动物保护协会,已经给驻各国中国大使写了抗议信,要求用更人道的方式,如,注射疫苗和无性繁殖等方法,控制狂犬病和流浪狗的数量。

The response may change the fate of the turions in the second year,and affect the maintenance of the populations.
在野外池塘中,利用3种不同营养状况的底质研究底质营养盐对菹草生长及养分分配的影响,结果表明:沉水植物菹草面对底质营养盐的胁迫出现了急性的生理生化反应,在生长初期叶片总的可溶性糖含量在肥沃的底质上高于贫营养底质上;根、茎、叶和石芽各构件都具有异速生长现象,并且表现规律不一样;菹草的根冠比随底质营养盐的不同而变化;随着营养条件对菹草生长胁迫加重,根、冠的异速生长愈明显,同时石芽的N∶P和C∶N比率显著受底质营养盐的影响,而菹草叶片和茎N∶P和C∶N比率不受底质肥力的影响,这些响应将改变石芽第2年的命运和影响种群的维持;在胁迫生境下,菹草首先分配资源到无性繁殖体--石芽上以便维持种群的延续,以回避策略应对底质营养盐胁迫。

The genetic study suggested that the carbendazim-resistance in these mutants could be steadily inherited by asexual and selfed reproduction, and the resistance was controlled by the same single major gene both in laboratory mutants and field resistant isolates, the different levels of resistance or the same resistant level in different strains maybe conferred by mutations at different sites or one site with different allelic mutations. The gene compensates for the sensitivity to MDPC was allelic to that governs the carbendazim resistance, but the mutation for increasing sensitivity to MDPC in this gene could get the pathogen highly resistant to carbendazim.
抗药性遗传研究表明,在所研究的抗药突变体中,抗药性在自交和无性繁殖后代中能稳定遗传;室內抗药突变体和田间抗药菌株对多菌灵的抗药性由同一个主效基因控制,但它们发生突变的位点不同或者同一碱基位点发生了不同的突变;对MDPC的敏感性也是由单个基因控制的,该基因与控制多菌灵抗性的基因是等位基因,当该基因发生对MDPC的敏感性增加的突变时会使病菌对多菌灵产生高水平抗性。
