半个多世纪以来,剑麻尽管列为热带的一种主要栽培作物,但仍然是原产于中美洲的野生植物。剑麻是用无性材料无性繁殖起来的,因此,其固有特征依旧不变,而选种对它也就是不必要的了。虽然剑麻是龙舌兰麻类中一种优越的纤维作物,并且有许多有价值的属性,特别是抗性和适应性,但通过育种还可以培育出一些优良类型。 For more than half a century, sisal, though classified as a major cultivated crop in the tropics, remains native to Central American wild plants. Sisal is vegetatively cloned with asexual material, so its inherent characteristics remain unchanged, and the selection is unnecessary for it. Although sisal is a superior fiber crop in agave, and has many valuable properties, especially resistance and adaptability, some good types can be bred by breeding.
