Abstract:
Vegetable-used jute (Corchorus olitorius L.) varieties viz.，‘Guimacai No.1’and ‘Guimacai No.2’，Chinese chives (CK1) and porret (CK2) were used as experiment material.Se contents in roots，stems，leaves，and fruits of ‘Guimacai No.1’ and ‘Guimacai No.2’ and its tender shoot at different stages were determined to use atomic fluorescence spectrometry.In order to clear and definite accumulation rule of selenium in different organs and different growth stages in vegetable-used Jute.The results indicated that，the root of ‘Guimacai No.1’ and ‘Guimacai No.2’ showed the strongest adsorption capacity of Se，Se content in roots were 5.98 μg?（100g）-1DW and 6.85 μg?（100g）-1DW.Then the stronger adsorption capacity followed by leaf，its content were 2.38 μg?（100g）-1DW and 3.16 μg?（100g）-1DW.Then the lower adsorption capacity were stem,its content were 1.74 μg?（100g）-1DW and 2.04 μg?（100g）-1DW.While that in fruits were lower than 1.0 μg?（100g）-1DW.The total Se content in different organs of ‘Guimacai No.1’ and ‘Guimacai No.2’ were 10.10 μg?（100g）-1DW and 12.05 μg?（100g）-1DW，and that of Chinese chives and porret were 9.97 μg?（100g）-1DW and 8.09 μg?（100g）-1DW，which indicated that ‘Guimacai No.1’ and ‘Guimacai No.2’ had stronger Se adsorption capacity than Chinese chives and porret.Furthermore，the tender shoots of ‘Guimacai No.1’ and ‘Guimacai No.2’ at top pruning stage and florescence presented 3.47 μg?（100g）-1DW and 4.32 μg?（100g）-1DW，3.07 μg?（100g）-1DW and 3.59 μg?（100g）-1DW of Se content，respectively;while that of seedling stage and fruiting stage were lower than 1.0 μg?（100g）-1DW.Se content of tender shoot at top pruning stage found to be higher than that of florescence.The tender shoots of vegetable-used jute was the main food part，Se content of tender shoots during the picking period was higher，so ‘Guimacai No.1’ and ‘Guimacai No.2’ were suitable to popularize cultivation as Se-enriched vegetable jute varieties.
