【摘要】 旱种条件下,不论水稻还是陆稻,全糖、全氮含量均高于水种条件,醇溶糖占全糖的比例较高,碳/氮比低;陆稻的醇溶糖占全糖的比例远远高于水稻,这一特性很少随种植条件的改变而产生很大的变化,这可能是其对旱地适应性较强的生理原因之一。同时发现:贮藏性物质的增加是水稻旱种条件下的重要生理表现。

【Abstract】 The eco—adaptability of rice (Oryza saliva L. ) to paddy and upland were studied with three varieties of lowland and upland rice under paddy and upland in 1985—1986. On upland, the rice plants expressed high concentration in carbohydr ate and nitrogen, high ratio in soluble sugars and low C/N ratio. The upland rice variety consisted of much more soluble sugars than that of lowland rice varieties. It was a eco—adaptability of rice plants to upland for increasing storage, especially in soluble sugars. Those rice varieties, which was with high ratio in soluble sugars, might be adapted to upland.
