1盆栽试验表明：6个水稻品种25日龄的秧苗根系放入冷却的蒸馏水（0～1℃）中2分钟，降低了茎的生长、分率成德率（特别是品种Johaboro）、籽粒产量（3～15g／盆）以及N、P、K、可溶性总糖、蛋白质和叶绿素含量，但增加了叶片脯氨酸含量。供试品种以Jo－haboro和IE6155表坎特别?
1 Pot experiments showed that the root system of 25-day-old seedlings of 6 rice cultivars was placed in cooled distilled water (0-1 ℃) for 2 minutes to reduce the growth of stems, the rate of ripening (especially the variety Johaboro), the grain yield (3 ~ 15g / pot) and N, P, K, soluble sugar, protein and chlorophyll content, but increased the content of proline in leaves. Test varieties to Jo-haboro and IE6155 form special?
