棉子酚

较此更早的一种转基因棉花中任何部分均不含棉子酚，但种植时招来多种害虫攻击。

The earlier version removed gossypol from all parts of the plant , which was then attacked by a variety of insects .

丹宁酸、棉子酚、番茄苷可抑制两种幼虫的生长，而以番茄苷抑制烟青虫的生长最为显著。

Tannic acids , gossypol and tomatin in the diet hamper the larval growth of both species and tomatin has more pronounced effect on the tobacco budworm .

研究者曾种植出另一种不含棉子酚的棉籽，并品尝了由其烹制成的棉籽餐，据报道其味道很好。

Researchers who had bred a different gossypol-free cottonseed had tasted the cottonseed meal , and reported that tasted good .

基因学家解释说，棉籽中含有丰富的蛋白质，但却不能为人类和大多数动物食用，因为棉籽内含有一种名为棉子酚的化学毒素。

Geneticist explained that the protein contained in cottonseed is good , but cannot be used by people or most animals because it contains a chemical toxin called gossypol .

这种转基因作物的茎和叶中依然含有棉子酚，以帮助抵抗害虫，但种子内该化学物质的含量显著降低。

Researchers said the modified plants continue to have gossypol in their stems and leaves where it helps resist insects , but the chemical is significantly reduced in the seed .
