设置4个水分胁迫处理(每3 d一次浇水,每7 d一次浇水,每15 d一次浇水和每30 d一次浇水),通过测定黄秋葵幼苗期、花期和收获期农艺性状,产量和产量构成因素、生理生化反应以及光合特性等指标,研究水分胁迫对黄秋葵生长、生理以及光合作用的影响。结果表明,随着水分胁迫程度的增加,各生育期黄秋葵农艺性状、籽粒产量以及产量构成因素均显著降低,重度缺水导致黄秋葵绝收;黄秋葵叶片的净光合速率、气孔导度均随着水分胁迫强度的增加而减少,叶片叶绿素含量随着水分胁迫程度增强,呈现先增加后降低的趋势;黄秋葵的可溶性糖、可溶性蛋白、游离脯氨酸、丙二醛含量均随着水分胁迫强度的增加而增加。 相似文献

以16个黄秋葵品种为材料,通过种植试验探究不同生态区的环境条件差异对黄秋葵品种数量性状的影响。结果表明：叶片长度、宽度在品种及地区间数据波动较大,因此这2个性状受品种及环境的互作效应较大;叶柄长在品种间差异较小,但受环境影响较大;果实厚度和果实长度在品种内容易出现不稳定的情况,而果实长度和果实直径在品种间的平均变异系数相对较小,分别为9.68%和8.68%,因此环境作用对其影响相对较小;单荚种子数在不同生态区表现出显著差异,易受环境影响;在品种类型中,矮杆类型、长果类型、红果类型的黄秋葵相较于其他类型更易受到环境的影响。 相似文献

Maize ogi was supplemented with 10 and 20% toasted and untoasted okra meals. Yields and chemical composition of ogi, and okra meal, and ogi substituted with okra meal were determined. Brabender paste properties of ogi and ogi substituted with okra meal mixtures were determined. Sensory acceptability of cooked colored and flavored ogi pastes was determined. Yields of ogi were 67.8% while yields of the toasted and untoasted okra seed meals were 35.1 and 39.9% respectively. Supplementing ogi with okra meal increased protein,ash, oil and fiber contents, but reduced ogi viscosity. Addition of yellow color did not significantly improve the color rating, but addition of vanilla flavor improved the flavor of ogi supplemented with untoasted okra meal significantly. 相似文献

The impact of okra leaf curl disease on four accessions of a local okra cultivar and four commercial okra cultivars was assessed in field conditions from June to October in 2007 and 2008. Disease incidence varied from 68.5% to 72.5% among accessions of the local cultivar while commercial cultivars were much less infected (8.7–16.2%). Diseased plants of the local cultivar suffered more reduced growth (58% reduction) than those of the commercial cultivars (39.6%). The number of marketable fruits per plant, the fruit length, fruit diameter and fruit weight which were subject to reductions of 26–61%, 19–64%, 6–42% and 23–63%, respectively. The overall yield losses were significantly higher in accessions of the local cultivar (26–55%) than in the commercial ones (4.4–9.6%). The average economic losses for one hectare of crop were estimated at of 11,100 USD and 1950 USD, respectively for the local and the commercial cultivars. 相似文献

土壤水分对黄秋葵苗期生长及光合作用的影响 总被引：5，自引：0，他引：5
以黄秋葵幼苗为材料。研究了不同土壤相对含水量(SRWC)(80％，60％，40％，20％)对其光合作用和生长的影响。结果表明：SRWC为60％时，植株生长最健壮，叶片的净光合速率高于其它处理：SRWC为40％时，植株日均净光合速率仅次于SRWC为60％条件下生长的植株，且高于其它处理，生长也未受到显著抑制；SRWC为20％时，黄秋葵的生长和光合作用均受到显著抑制：SRWC为80％时，植株细长，根冠比较小。因此认为，黄秋葵苗期适宜的SRWC为40％-60％。 相似文献

This study investigated the emulsifying properties of okra (Hibiscus esculentus), dika nut (Irvingia gabonensis) and khan (Belschmiedia sp.), three African food hydrocolloids used to thicken and flavor soups. Results showed that khan has an emulsion potential approximately 20 and 100 times higher than the second and the first, respectively. A kinetic study indicated that the mechanism involved formation of thick and strong interfacial gum films around the oil globules, in addition to a high Water Absorption Capacity and weak gelling behavior of khan gum in solution. These results indicated that, when used in soups, which are typical oil/water emulsions, khan contribute both to thickening and stabilizing of the emulsion, whereas okra and dika nut functioned more as thickeners than as emulsion stabilizers. 相似文献

The okra seeds of variety Pusa sawani were analysed for protein, non-protein nitrogen, total free amino acids, lysine, and tryptophan from the 7th day to the 42nd day after flowering. Starch, total sugars and oil percent were also estimated in these seeds. During the early stages of maturation, the soluble components (non-protein nitrogen, free amino acids and total sugars) were found in higher quantities than in the later stages. Protein, oil and starch contents increased gradually from day 7 to day 42. The rate of accumulation of oil was found to be at the highest level between 21–28 days after flowering, while the rate of protein deposition was greatest between days 35–42. Inditiation of seed maturation seems to start 21 days after flowering in okra seeds. 相似文献

The nutritive value of Egyptian varieties of fresh and sun-dried okra pods as well as okra seeds were studied. These varieties were: Baladi, Eskandarani, and Gold Coast.Pods of the three varieties were shown to contain approximately the same amount of water. Fiber and ash were considerably high while carbohydrate and fat contents were low.Fresh and sun-dried okra pods were found to contain high amounts of clacium and iron.Sun-dryness decreased water content, while other component increased considerably.Seeds were found to contain high concentration of protein, fat, ash, fiber, phosphorous, and iron.

Es handelt sich um folgende Sorten: Baladi, Eskandarani und Gold Coast.Die Früchte aller drei Sorten enthielten annähernd den gleichen Anteil Wasser. Rohfaser und Asche waren ziemlich hoch, während Kohlehy drate und Fett niedrig waren.Sowohl frische, als auch sonnengetrocknete Hibiscus-Früchte enthielten beträchliche Mengen an Calcium und Eisen.Die Samen sind sehr reich an Protein, Fett, Asche, Rohfaser, Phosphor und Eisen.相似文献

Variation in 10 seed characteristics was studied in the species groups, common okra (Abelmoschus esculentus), an African species with edible pods, and in related species. The groups differed significantly in 9 of the 10 characteristics. A relatively large hull fraction limited protein and oil contents. Seeds of common okra contain more oil, less protein, and less cyclopropenoid fatty acids than those of African okras, and have a larger kernel fraction, a higher percentage of large seeds, heavier seeds, more pubescence, and a lighter color. Protein and oil contents were inversely correlated. Gossypol or gossypol-like compounds were lower in common okras than in related species. Varieties particularly low in toxic substances were identified. 相似文献
