Effects of different salt solutions pretreatment on the germination of helianthus annuus 不同盐溶液浸种对向日葵种子萌发的影响

The irrigation with seawater had n ' t affected the inulin contents hi helianthus tuberosus ( l . ) tubers , and the contents of inulin in helianthus tuberosus ( l . ) were from about 40 % to 65 % 利用海水资源对菊芋进行灌溉不影响其块茎中菊糖的含量，菊芋块茎中菊糖含量范围为40到65左右。

My experiment can mostly include two sections : the first one was a pot experiment which was carried out in the greenhouse to study the physiological responses of helianthus tuberosus l . seedlings to salt and water stress ; the second one was a field experiment which was carried out in laizhou , shandong province to study the effects of seawater irrigation on helianthus tuberosus l . and soil 本试验由温室盆栽耐盐耐旱试验和大田海水灌溉试验两大部分组成：温室盆栽试验主要通过砂培的方法，研究了幼苗期菊芋在盐分和水分胁迫下的生理反应；大田试验在半干旱的山东莱州地区进行，研究了海水灌溉对菊芋及其土壤的影响。

The stem of helianthus tuberosus ( l . ) had the ability of containing high contents of na + and cl - , and selectively absorbed k + in high proportions seawater irrigation ; the above and tubers yields of helianthus tuberosus ( l . ) had n ' t decreased until at the 50 % proportions seawater irrigation where the yields decreased by 37 % and 32 % in contrast to freshwater - irrigated . it meant that through natural weather , reduction of yields was occurred by salinity of irrigation water but the reduction was not significant until the proportions of seawater in irrigation water were the same as 50 % or above it 海水灌溉下，菊芋的茎部具有明显的贮cl ~ - 、 na ~ +能力，在高浓度海水灌溉下菊芋整个植株对k ~ +具有较高的选择吸收性；菊芋地上部和块茎产量在30海水处理范围内，没有减产趋势，在50海水灌溉下减产幅度分别为37和32 ；可见，正常自然条件下的海水灌溉，对产量的影响主要和灌溉水的浓度有关，但只有在50处理下才显著减产，低于50产量并无差异。
