不同处理方法对朝天椒生长及品质的影响 总被引：1，自引：0，他引：1
为探索不同处理方法对朝天椒生长及品质的影响,以贵州地方朝天椒品种遵辣6号、遵辣9号和遵辣10号为试验材料,播种前对种子进行超声波处理,于辣椒定植期在根部施用草根8号生物有机肥,探究不同处理方式对辣椒营养生长、产量及品质的影响。结果表明,超声波处理的辣椒株高、基茎、根重等农艺性状比ck高,但低于既经过超声波处理,又施用草根8号的辣椒;超声波处理具有明显的增产效果,与ck相比,遵辣6号、9号、10号分别增产32.32%,30.29%,5.68%,既经过超声波处理,又施用草根8号的遵辣6号、9号、10号分别增产57.07%,36.00%,16.81%;此外,超声波处理和施用草根8号均具有一定的提质效果,特别是辣椒的维Vc含量和辣椒素含量。研究表明,超声波处理和施用草根8号均对辣椒的生长发育、增产和提质具有促进作用,以既经过超声波处理,又施用草根8号处理的效果最佳。 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

Efficiency of water use of early plantings of sunflower 总被引：4，自引：0，他引：4

Rain fed crop production in Mediterranean environments depends to a large extent on strategies that avoid the intense summer drought. Early plantings of sunflower have given consistently higher yields in such environments, but the basis for such yield increases has not been explored. We conducted two field experiments at Cordoba (Spain) to investigate the effects of an early and a late planting date on the components of water-limited crop productivity; namely, water use (T), water use efficiency (TE) and harvest index (HI) of sunflower. The results were generalized by simulating rain fed sunflower yields, under early (1 January) and late (15 March) plantings, for a 25-year period with the aid of a simulation model of the Ceres type (OILCROP-SUN) which has been validated in Cordoba. Experimental seed yields of early plantings in 1989 and 1996 were 2.0 and 3.0 t ha−1, while late plantings yields were 1.3 and 2.4 t ha−1, for the 2 years. Average simulated yields were 2.7 ± 1.1 and 1.9 ± 0.7 t ha−1 for early and late plantings, respectively. For the 2 years, T of early plantings was higher than that of late plantings, but the response of TE and HI to planting date was not the same in the two experiments. In the simulation exercise, T and TE of early plantings were consistently higher than those of late plantings, while there were no differences in the HI for the two planting dates. We conclude that early plantings of sunflower increase rain fed yields by increasing both T and TE, while the impact of planting date on HI very much depends on the crop water stress pattern, which is quite variable from year to year even in the predictable Mediterranean environment. 相似文献

The cotyledon and hypocotyl of eight varieties of alfalfa( Medicago sativa L. )are used to study the effect of different cultivation procedures and genotypes on embryogenic callus and embryoid induction,plant development and transplant of alfalfa.The varieties of alfalfa with high embryoid induction rate and high differentiation rate are screened. A high frequency regeneration system for alfalfa tissue culture is established:which is benifical to the gene transformation of alfalfa. 相似文献
