摘要

在完全营养液条件下（Ｋ＋４０ｍｇ／Ｌ），耐低钾基因型水稻品种“湘早糯１号”比不耐低钾基因型水稻品种“双白－２１１－竹印”分蘖期全株、根、茎秆的Ｋ，Ｎａ，Ｃａ，Ｍｇ，Ｆｅ含量减少，根中的Ｍｇ含量稍多；孕穗期全株、根、茎秆的Ｋ，Ｍｇ含量增加．Ｆｅ含量在茎秆也多．在低钾（Ｋ＋３ｍｇ／Ｌ）营养液条件，“湘早糯１号”分蘖期植株苗高、苗干重、根干重、根体积及植株的Ｋ，Ｍｇ，Ｆｅ；茎秆的Ｋ，Ｍｇ；根的Ｋ，Ｎａ，Ｃａ，Ｍｇ，Ｆｅ含量均比“双白－２１１－竹印”增加；孕穗期全株、根、茎秆的上述５种营养元素含量都增多，茎秆的Ｆｅ含量相近．耐低钾基因型水稻品种“湘早糯１号”在低钾（Ｋ＋３ｍｇ／Ｌ）条件下抽穗率达９６％，结实率达３１．１％，不耐低钾品种“双白－２１１－竹印”抽穗率少于１０％，且不结实

Abstract

The experiments resulted that less mineral element contents of K

Mg and Fe in roots

shoots and whole seedling

but more Mg in root at tillering stage of rice variety "XZN 1" shown than those of rice variety "SB 211 ZY" at Yoshida’s complete nutrition solution. Under which at booting stage the root

stem and the whole plant of "XZN 1" have shown more K

more Fe in stem compared with "SB 211 ZY". Otherwise at the seedling stage of "XZN 1"the seedling height

seddling dry weight

root volume

root dry weight and mineral element contents of K

Mg in shoots

Mg and Fe in roots

Mg and Fe in the whole seedling have abserved over that of "SB 211 ZY"

while K concentration was K + 3mg/L. During which cultural condition at the booting stage of "XZN 1" more mineral element contents of K

Mg and Fe in roots

stems and whole plant as well as less Fe in stem were found in comparison with "SB 211 ZY". The panicle extension about by 96% and filled grain about 31.0% of "XZN 1"

panicle extension less than 10% and never filled grain in "SB 211 ZY" were appeared.
