近年来,随着国家种子工程和种子产业化的不断实施,青海种子加工业有了较快发展。但由于起步较晚,目前在不少方面尚处于探索阶段,出现的一些问题不容忽视。1存在的问题1.1种子加工种类混乱、程序过于简单目前,青海使用的种子加工设备主要以小型单机为主,用以加工小麦、青稞、豆类等作物种子。由于缺乏小粒种子设备,对蔬菜种子的精选加工基本没有开展。就小麦、青稞、豆类等作物种子加工而言,也因种子加工机械不配套,许多加工点只是简单的初级加工,即清选后进行定量包装,这与种子规范加工所规定的预清、精选分级、药物处理、计量、包装等要求相差甚远,还达不到种子加工的标准,在一定程度上影响了青海农业生产向现代  相似文献

动物蛋白和植物蛋白是人体蛋白的两个重要来源,植物蛋白主要是从谷物及豆类中获得特别是豆类蛋白营养价值高,不含脂肪和胆固醇,富含异黄酮、低聚糖、膳食纤维和多种矿物质,它的蛋白质含量是牛奶的17倍、猪肉的3倍、牛肉的2倍、面粉的5倍、大米的7倍左右。用衡量蛋白质质量的PDCAAS方法测算,以1为最高分,豆类蛋白、牛奶蛋白、鸡蛋蛋白均为1分,牛肉蛋白为0.92分,小麦蛋白只为0.25分。可以说,豆类食品是营养物质的宝库。除此之外,豆类食品还可以预防多种疾病,大量的临床试验表明,每天食用25g豆类蛋白可减少心脏疾病的危险,关于豆类蛋白的抗癌功能也得到有关专家的论证。  相似文献

Common bean (Phaseolus vulgaris L.) is the most important food legume crop in Africa and Latin America where rainfall pattern is unpredictable. The objectives were to identify better yielding common bean lines with good canning quality under drought, and to identify traits that could be used as selection criteria for evaluating drought‐tolerant genotypes. In all, 35 advanced lines were developed through single seed descent and evaluated with a standard check under drought and irrigated conditions at two locations over 2 years in Ethiopia. Grain yield (GY), pod number per m2, seed number per m2 and seed weight decreased by 56%, 47%, 49% and 14%, respectively, under drought stress. Eight genotypes had better yield with good canning quality under drought compared to the check. Moderate to high proportion of genetic effects were observed under drought conditions for GY and yield components compared to genotype × environment effects. Significant positive correlations between GY and pod harvest index (PHI) in drought suggest that PHI could be used as an indirect selection criterion for common bean improvement.  相似文献

Experiments were performed to evaluate seed germination and seedling growth in simulated drought as screening techniques for drought tolerance raring. Several laboratory screening tests were evaluated for ability to estimate drought resistance in 18 cultivars of legume plants (field bean, soybean, field pea, lupine). Drought was simulated by a water solution of mannitol of chemical water potential ψ= -0.3 and -0.6 MPa. Both solutions significantly affected seed germination (final germination and promptness index) and seedling growth parameters (seedling height, dry matter of shoot and root as well as leaf injury by drought and high temperature). The tested cultivars could be grouped as drought resistant and drought susceptible plants. Drought tolerance ratings of legume plants in the laboratory tests were, on the whole, consistent with the ratings based on estimation of direct effects of soil drought on seed yield in field experiments. Measurements of electroconductivity of leaf diffusate to evaluate invisible injury caused by drought or high temperature were found to be an adequate criterion for drought tolerance rating. It is concluded that tolerance to drought stress in growing seedlings can be screened for by using mannitol containing nutrient solution. According to the results collected in this research, varieties differences in seed germination, seedling growth and leaf injury affected by drought or heat temperature were evident, however, not all treatments appeared to be equally useful for screening of legume species cultivars.  相似文献

With world population expected to reach 9.2 billion people by 2050, improved irrigation methods will be needed to increase the productivity of agricultural land and improve food supply worldwide. The objective of this work was to examine the effect of regulated deficit irrigation (RDI) and alternate furrow irrigation (AFI) on the yield and yield components of two legume species (common bean and mungbean) produced as a second crop following winter wheat in Uzbekistan, Central Asia. Water relations and crop development were also examined. The research was conducted during two successive growing seasons in the Fergana valley. Production of mungbean using the severe stress RDI treatment in combination with AFI resulted in the highest yields with the lowest quantity of applied water in 2004. In addition, yields of common bean in the moderate stress treatment were not different from the recommended schedule, although irrigation events were decreased from 4 to 2. AFI did not reduce yields, and it did not interact with RDI to reduce yields further. In general, mungbean yields were higher than those of common bean. The combination of AFI and RDI can allow legume production with reduced water inputs.  相似文献

Soya bean [ Glycine max (L.) Merr.] genotypes with modified unsaturated fatty acid profiles in seed oil have been developed. Higher oleic (18:1) and lower linolenic (18:3) acids are desirable for increased use of soya bean oil in food and industrial applications. The environment affects levels of unsaturated fatty acids in soya bean and it is important that desired components of seed oil are produced across a range of growing conditions. Our objective was to determine whether irrigation affects fatty acid levels in soya bean with altered fatty acid profiles. Seven modified oil genotypes which included elevated oleic acids, and/or reduced linolenic acid, along with two common soya bean varieties were evaluated with and without irrigation (rain fed) in four environments in each of 2 years. Irrigation generally had no significant influence on unsaturated fatty acid accumulation in seed oil in soya bean genotypes with altered fatty acid profiles. However, irrigation tended to show desirable effects on 18:1 and 18:3 contents in the genotypes studied. Oleic acid tended to be higher in eight of the nine genotypes and linolenic acid was lower in six of the nine genotypes under irrigation vs. rain fed treatments.  相似文献

Eighteen cultivars of legume species (field bean, soybean, field pea, lupine) were screened for drought tolerance in 3 year-long field experiments. The aim of the investigations was to evaluate the generic variation of drought susceptibility of the tested varieties. The experimental plots were equipped with an installation which enabled the limitation of the water content in soil and soil irrigation. The applied drought susceptibility index (DSI) considered the relations between seed yield of plants under drought conditions (YD) and that under conditions of good soil watering (YIR) as well as their dependence on the drought severity index (DS). The use of the index divided the cultivars into two groups of different drought tolerances. The group of drought resistant cultivars characterized by mean values of the DSI index < 0.31 comprised field bean cultivars Bourdon, Gobo and Nadwislanski, soybean cultivars Aldana, Polan and Progres, field pea cultivars Miko and Solara and lupine cultivars Popiel and Bac. To the drought sensitive cultivars with DSI > 0.44 belonged Victor and Bronto of field bean species, Bareness and Mige of field pea species and Emir of lupine species. In general, the resistant cultivars when compared with the susceptible ones were characterized by lesser yield of seeds, which, however, was more stable both under conditions of drought and moistured plots. Any dependence of the degree of drought tolerance on the duration of the particular periods of plant growth was not observed in the experiments, however, both in’ drought susceptible and drought resistant cultivars there appeared the tendency to shorten the development phases under drought and to prolong them under artificial irrigation. In general, based on the results obtained, it can be concluded that legume plants belong to the species sensitive to water supply. The observed decrease of plant seed yield under moderate natural soil dryness in the year 1993 differed only a little from that found in experiments in the years 1994 and 1995, when soil dryness was much more severe.  相似文献

In common bean, the most abundant proteins of the lectin family (arcelin, phytohaemagglutinin and α-amylase inhibitor – APA proteins) are major antinutritional factors of the seeds. Reduced protein digestibility and high toxicity at the intestinal level are the causes of their antinutritional effect. Bean lines producing seeds without the lectins mentioned above were developed to improve nutritional characteristics of bean seeds used for human consumption and, potentially, for animal feeding. The genetic trait was transferred from a wild bean accession into a number of bean cultivars. The 1 : 3 'lectin-free/lectin-containing seeds' segregation ratio hypothesis was confirmed by chi-square analysis in the F2 progenies. Four lectin-free stable lines, P500, P501, 938 and 586/8 (white seeded), and 44 climbing breeding lines, have been developed. The 'white seed coat' trait, correlated with a reduced amount of tannins and polyphenols in bean seeds, has been introduced in our lectin-free materials to further improve their nutritional characteristics. The field performance of P501, 938 and 586/8 and that of their lectin-containing parents, was evaluated on 2007 in two locations. Dry seed yield, seed emergence, plant height, plant growth duration, average weight and germination capacity of the produced seeds were surveyed and statistically analysed. At the location of Battipaglia (Salerno), the dry seed yield value of the lectin-free line 938 (3.74 t/ha) and that of one of its parent, the CIAT line BAT 881 (3.65 t/ha), were significantly higher than those of all other lines tested. Germination percentage of lectin-free lines, recorded 3 days after sowing, was significantly higher than that of controls.  相似文献
