摘要

在低钾土壤培养和营养液培养的条件下

采用植株含钾量、吸钾速率和钾素利用率并结合植株根系形态特征

对蕺菜属(Houttuynia Thunb.)16份不同基因型材料的富钾能力进行筛选。结果表明

峨眉蕺菜W01-86以及蕺菜W01-34和W01-71在低钾土壤培养和溶液培养时植株含钾量分别高于9.0%

5.50%

吸钾速率大于1.50μmol/(g.h)

低钾土壤培养和溶液培养时的钾素利用率分别高于2.50

0.30g/g

为富钾基因型;W01-4和W01-99低钾土壤培养和溶液培养时的植株含钾量分别低于8.5%

5.0%

吸钾速率小于0.65μmol/(g.h)

低钾土壤培养和溶液培养时的钾素利用率分别低于2.00

0.30g/g

为低钾基因型。

Abstract

Under the low potassium solution and soil cultures conditions

capability of enrichment in potassium of 16 different genotypes in genus Houttuynia Thunb.were screened by comparing the potassium contents

potassium uptakes and utilization ratios

and the morphology characters of root.H.cordata was cultured under low and normal potassium solution conditions

the result showed that the genotype of H.emeiensis Z.Y.Zhu et S.L.Zhang(W01-86)

H.cordata(W01-34 and W01-71) had high capability of enrichment in potassium
