[Biological characters of rice on P-deficient soils with different pH value].

Abstract excerpt

With pot culture, this paper studied the biological characters of four low-P tolerant rice genotypes 99011, 580, 508 and 99112 and two low-P sensitive rice genotypes 99012 and 99056 on three P-deficient soils with different pH. The results indicated that on test soils, 580, 508 and 99112 had similar low-P tolerant ability. 99011 had poor low-P tolerant ability on alkaline soil, with its relative grain yield being...
