作物的抗旱性是一种复杂的性状,它受多基因控制,亦受修饰基因的影响,其表现涉及到不同的特性,有形态的(如根系的发育分布与其生活力;叶的腊质;叶表面茸毛程度;叶片大小和分蘖力等)、生理的(如叶片的持水力;气孔的脱水反应等),以及生化上的(如酶活性的改变和脯氨酸积累状况等)。对这些特性的相互作用,以及耐旱遗传机制的问题尚未弄
Crop drought resistance is a complex trait that is controlled by multiple genes and is also affected by the modified genes. Its performance involves different traits, morphological (such as the development and distribution of root systems and their viability; the waxiness of leaves; Leaf surface hairiness; leaf size and tillering ability, etc.), physiological (such as leaf water holding capacity; stomatal dehydration reaction, etc.), and biochemical (such as changes in enzyme activity and proline accumulation status, etc.). The issue of the interaction of these traits, as well as the genetic mechanism of drought tolerance, has not been addressed
