摘要
为探究不同栽培方式下大蒜(Allium sativum L.)各器官出苗期、萌芽期、分化期、膨大期蒜氨酸含量变化,以2种大蒜为材料,分别进行土培和水培试验,采用HPLC法测定2种培养方式下大蒜植株中根、鳞茎、叶片3种器官的蒜氨酸含量.结果表明,在出苗期、萌芽期、分化期,土培方式下2种大蒜植株根中蒜氨酸含量均呈先下降后升高的趋势,水培方式下2种大蒜植株根中蒜氨酸含量均基本保持不变;土培方式下2种大蒜植株鳞茎中蒜氨酸含量均呈先降低后升高的趋势,水培方式下2种大蒜植株鳞茎中蒜氨酸含量均呈先升高后降低再升高的趋势;土培方式下2种大蒜植株叶片中蒜氨酸含量均呈下降趋势,水培方式下2种大蒜植株叶片中蒜氨酸含量均呈升高趋势.综上,2种栽培方式下不同生长期大蒜植株各器官蒜氨酸含量变化存在差异,在萌芽期、分化期,水培方式下2种大蒜不同器官中蒜氨酸含量均高于土培,且在出苗期、萌芽期、分化期,水培方式下2种大蒜植株叶片中蒜氨酸含量均高于其他器官.
Abstract
To investigate the changes in allicin content in various organs of garlic(Allium sativum L.)during the seedling,germina-tion,differentiation,and expansion stages under different cultivation methods,two types of garlic were used as materials for soil and hydroponic experiments,respectively,and the HPLC method was used to determine the allicin content in roots,bulbs,and leaves of garlic plants under two different cultivation methods.The results showed that during the emergence,germination,and differentiation stages,the allicin content in the roots of both garlic plants under soil cultivation showed a trend of first decreasing and then increas-ing,while under hydroponic cultivation,the allicin content in the roots of both garlic plants remained basically unchanged;under soil cultivation,the allicin content in the bulbs of two garlic plants showed a trend of first decreasing and then increasing,while under hy-droponic cultivation,the allicin content in the bulbs of two garlic plants showed a trend of first increasing,then decreasing,and then increasing;under soil cultivation,the allicin content in the leaves of both garlic plants showed a decreasing trend,while under hydro-ponic cultivation,the allicin content in the leaves of both garlic plants showed an increasing trend.In summary,there were differences in the changes of allicin content in various organs of garlic plants at different growth stages under two cultivation methods,during the germination and differentiation stages,the allicin content in different tissues of two types of garlic grown in hydroponics was higher than that grown in soil,and during the emergence,germination,and differentiation stages,the allicin content in the leaves of both gar-lic plants was higher than that in other organs under hydroponic conditions.
