番茄灰霉病(Botytis cinerea)是一种世界性的重要病害,该病主要为害果实造成烂果, 对保护地番茄生产构成极大威胁[1].浙江温州自20世纪90年代初开始发生蔓延, 现已成为番茄生产的头号病害,重发田块病果率高达40%以上,严重影响产量.过去,在温州市对付该病主要依靠化学防治,由于频繁施药,病菌抗药性问题突出,果实污染严重,防治不尽人意,为了探讨更好、更有效的防治途径,笔者于近年对番茄灰霉病的果实染病特征及其物候防治新技术进行了试验研究,取得了理想效果,现将结果报告如下. 相似文献

番茄早(晚)疫病是焉耆垦区加工番茄生产面临的主要病害,尤其是2007年,早(晚)疫病更是严重发生,给番茄生产造成很大损失.由于常年使用以往一些药剂进行防治,病菌已对农药产生抗性,而且一部分农药已经不能满足新的无公害绿色食品生产要求,农药残留问题已不可忽视.鉴于此,我们对高效、低毒农药"72%霜利克"进行药效试验,并获得了满意的防治效果. 相似文献

香蕉是热带亚热带发展中国家重要的粮食作物和碳水化合物来源。但近年来,香蕉生产受到严重的病虫危害。大多数香蕉栽培品种是三倍体,生长周期长,而且不孕。由于没有种子,给繁殖和育种带来一定的困难。遗传转化技术的发展为香蕉品种的改良提供了一种有效的手段。香蕉的遗传转化方法有电激法、基因枪法、农杆菌介导法等。农杆菌介导法的应用是香蕉品种改良的一个重大突破。香蕉遗传转化的外植体也发展到多种,有原生质体,胚性细胞悬浮系,分生组织,以及横切薄片等。近几年,随着分子生物学的发展,出现了转化效率更高,重复性更好的香蕉遗传转化技术。如农杆菌和基因枪结合法,离心辅助农杆菌介导法、真空渗透技术等。这些新技术新方法的出现,必将推动香蕉产业高速发展。 相似文献

Automobile comfort dynamic simulation is necessary when we predict and evaluate the comfort of a automobile or optimize performance of automobile. The nine DOF vibration model of automobile is established , which acts root mean square value of body in multiple work conditions as comfort evaluation indices. Based on the comfort simulation, the Hongyan 1160 is predicted in the way of comfort. The programmes can be used in many different automobiles . The computational result indicates that the model can simulate vibration of automobile truly. It is significant to research automobile comfort evaluation to optimize performance of automobile and comfort simulation .The computational program can be applied to optimize or simulate which has some reference value. 相似文献

Applicability of molecular markers in the context of protection of new varieties of cucumber 总被引：2，自引：0，他引：2

The growing number of candidate varieties presented every year at each national Plant Variety Protection Office and their decreasing genetic variability forces strategies to be adopted that will reduce costs without losing rigour when deciding about the acceptance or rejection of a candidate variety. Molecular markers have been envisaged as a reliable tool to establish differences, but can molecular markers be used for assessing distinctness? A comparison between a molecular and a morphological characterization of 41 seed samples belonging to 36 cucumber varieties and including several external controls has been carried out to investigate the applicability of molecular markers in the context of distinctness, uniformity and stability (DUS) tests and the protection of new varieties. Both types of character indicate the same relationships among main groups, Dutch and Beth‐Alpha types, and Gerking and Slice types, the correlation between distance matrices being only 0.6489. Varieties considered uniform for morphological traits proved not to be so for molecular markers. Therefore, molecular characterization is not offering the same estimates of uniformity and relatedness between varieties as does morphological characterization. External controls were used to establish distinction limits with morphological and molecular dendrograms to focus on those varieties, which were suspiciously similar. The results with cucumber show that molecular identity could be used to assess any lack of distinctness and so corroborate the morphological assessment of candidate varieties. The morphological trait ‘type’ provides distinct characterization of varieties and the molecular characterization of candidate varieties could be used to design better field experiments to assess distinction within each group of morphological cucumber type. 相似文献
