Abstract

The effects of crude oil pollution on the seedling and subsequent growth phases of Zea mays Var. F27, (Corn) Abeimoschus esculentus (Okro) and Capsicum frutescens (Pepper) were investigated. Zea mays seedlings and Capsicum plants were most susceptible to crude oil spillage at 31 m⁻². Mature Z. mays and Abelmoschus esculentus were fairly tolerant to crude oil doses of 31 m⁻² and 61 m⁻². In the spraying experiments crude oil was found to be a potent contact herbicide. Z. mays and Abelmochus esculentus were completely destroyed in one or two weeks by death and maceration of vegetation or by defoliation. Capsicum frutescens rapidly recovered from defoliation with a flush of new leaves and branches 3 weeks after oil treatment.

Among other factors, the phytotoxic, hydrophobic and other stress imposing properties of crude oil were suggested as causes of death to plants.

原油污染对玉米、青豆和辣椒生长的影响

研究了原油污染对玉米(Zea mays Var. F27)、阿贝莫斯(Abeimoschus esculentus)和辣椒(Capsicum frutescens)苗期及后续生育期的影响。玉米幼苗和辣椒植株对31 m−2的原油泄漏最敏感。成熟的黄颡鱼和白颡鱼对31 m−2和61 m−2的原油剂量具有较强的耐受性。在喷施试验中发现原油是一种强效的接触除草剂。在1 ~ 2周内，由于植被的死亡和浸渍或落叶等原因，褐毛小蠊和绿毛小蠊被完全消灭。精油处理3周后，辣椒的落叶迅速恢复，新叶和新枝茂盛。其中，原油的植物毒性、疏水性和其他胁迫特性被认为是植物死亡的原因。
