Enlargement Quotient to Estimate Leaf Area in Two Cultivars of Okra (Abelmoschus esculentus [L.] Moench)

Two cultivars of Okra ( Abelmoschus esculentus [L.] Moench) were used to compare the relationship between linear dimensions of leaf and leaf area. Formula A = eL² (where A = leaf area, e = enlargement quotient and L = midrib length of leaf) determined leaf area more accurately.     

不同采摘期对黄秋葵果实性状和品质的影响

干旱对黄秋葵的影响

[目的]研究在土壤干旱条件下不同黄秋葵种质生长和光合作用的差别。[方法]以22个黄秋葵种质为材料,采用干旱伤害率分析法,对其抗旱性进行评价。[结果]干旱对004-5的株高,生物产量和光合作用的伤害率低,对B015的伤害率高;土壤相对含水量下降到30%～35%时,各种质光合指标的日均值有明显差异。[结论]004-5的抗旱性最强,B015对干旱最敏感。

Efficacy of mulching, irrigation and nitrogen applications on bottle gourd and okra for yield improvement and crop diversification

An on-farm irrigation trial conducted on the upland of Chitwan valley of Nepal evaluated the amount and frequency of irrigation as well as the effect of nitrogen fertilizer and straw mulch applications on the performance of bottle gourd and okra vegetables. The experiment was laid out on split-split-plot design with fertilizer as main-plot factor, frequencies of irrigation as sub-plot factor, and amount of irrigation as sub-sub-plot factor. Data analysis revealed that frequency and amount of irrigation had a significant interaction effect on the number of nodes that emerge before the opening of the first flower in bottle gourd. Likewise, a significant effect of mulching was observed on the number of primary branches (P = 0.05). Number of nodes and primary branches both contributed to higher production of bottle gourd. Results also indicated that frequent application of higher amount of irrigation to bottle gourd could lead to reduced water productivity and suffer from yield losses. In the case of okra, low level of nitrogen application (30 kg N ha⁻¹) with low but daily watering had significantly higher yield (1,365 g plot⁻¹) than from higher level of nitrogen application (90 kg ha⁻¹) (P = 0.01). Interaction effect of all factors was also significant (P = 0.05) on the fruit yield of okra which implied greater value of smaller irrigation to contribute to increased returns to farmers by improving production level of okra in this area of Nepal

黄秋葵籽粕分离蛋白理化性质及营养评价

[目的]分析榨油后黄秋葵籽粕的分离蛋白理化特性和营养价值。[方法]利用碱溶酸沉的方法提取分离蛋白,对分离蛋白的溶解性、乳化性、起泡性、蛋白质分子量范围和氨基酸含量进行分析。[结果]分离蛋白在等电点处理化性质差,富含亮氨酸,苏氨酸为第一限制性氨基酸,蛋白质的主要亚基在20～26 kD。[结论]黄秋葵分离蛋白具有较大的开发价值。     

黄秋葵新品种DUS测试叶部性状的选择

为准确筛选和确定黄秋葵新品种DUS测试性状,以180 份黄秋葵种质资源为试验材料,对其叶部的形态特征进行观测和采集数据,并比较15 个性状在不同参试材料间的差异。结果表明,在所选择的性状中,4 个质量性状、5 个假质量性状和4 个数量性状存在显著差异,13 个性状可作为黄秋葵DUS测试的基本性状。     

杏鲍菇菌渣对黄秋葵生长性状的影响

[目的]探讨杏孢菇菌渣栽培黄秋葵的可行性。[方法]采用菌渣作为黄秋葵大田栽培的基质肥料,在相同种植面积内施用不同量的菌渣,以不施用菌渣作对照,按黄秋葵栽培的常规管理方式进行田间管理,对黄秋葵植株的生长速度、茎粗、开花数、结荚数及鲜荚产量进行比较研究。[结果]在相同的栽培条件下,黄秋葵鲜荚产量随着菌渣施用量的增加而增加,以使用杏鲍菇菌渣量为7 kg/m2的处理黄秋葵鲜荚产量最高,是对照组的224.16%。[结论]该研究可为食用菌菌渣在农作物上的应用提供理论指导。
