摘要
以"长绿箭"苦瓜为试材,利用盆栽控水法,研究了接种球毛壳菌(Chaetomium globosum)ND35对不同水分处理条件下苦瓜幼苗生理特性的影响,以期为球毛壳菌ND35在苦瓜生产中的应用提供参考依据。结果表明:与未接种对照组相比,接种球毛壳菌ND35各处理组的叶片相对含水量提高1.98%~5.19%;叶片脯氨酸含量降低38.48%~58.58%;丙二醛含量降低6.89%~26.10%;可溶性蛋白质含量提高23.65%~27.24%。在中度和重度水分胁迫条件下,接种球毛壳菌ND35较未接种对照组的苦瓜叶片中SOD活性分别提高42.32%和45.72%;POD活性分别提高28.47%和21.73%;CAT活性分别降低69.44%和49.15%。在不同水分处理条件下,接种球毛壳菌ND35显著提高了苦瓜幼苗的相对含水量、可溶性蛋白质含量和抗氧化酶活性,明显降低了脯氨酸含量和丙二醛含量。
Potted cultured‘Changlyujian＇bitter gourd was used as test material,effect of Chaetomium globosum ND35 on physiological characteristic of bitter gourd under drought stress was investigated under different water treatments,in order to provide references for application of Chaetomium globosum ND35 in production of bitter gourd.The results showed that compared with control group non-inoculated,leaves relative water content increased 1.98% -5.19% in each group inoculated with C.globosum ND35;content of proline decreased 38.48% -58.58% ;content of MDA decreased 6.89% -26.10% ;content of protein increased 23.65% -27.24% .Under condition with water stress at middle and serious degrade,compared with control group non-inoculated,SOD activity in leaves of bitter gourd inoculated with C.globosum ND35 increased 42.32% and 45.72% ,respectively.POD activity increased 28.47% and 21.73% ,respectively.CAT activity decreased 69.44% and 49.15% ,respectively.Inoculation with C.globosum ND35 was significantly able to improve the relative water content,protein content and antioxidant enzymes activities,but contents of proline and MDA were lower than that of non-inoculated group under different water treatment.
