【摘要】 通过60Coγ射线辐照姬松茸菌丝体处理,研究其对子实体中稀土和P,K等矿质元素含量的影响以及相关性。结果表明:60Co辐照导致姬松茸子实体中稀土和P,K等矿质元素的含量发生极显著性变化(P<0.01),而且不同元素含量因辐照剂量不同其相应的变化规律亦各异;其中Pr和Mo含量随辐照剂量的增加而增加,当辐射处理达到一定剂量(1.5 KGy)元素含量又减小;而Yb含量随辐照剂量的增加而减小。K和Cu含量随剂量的变化具有相似的规律,均为先随剂量的增加而减少,当剂量增加到1.5 KGy时,元素含量又增大且大于前3个处理(0,0.5,1.0 KGy)的值。通过相关分析表明,子实体中稀土和P,K等矿质元素含量同辐照剂量存在不同程度的相关关系,而且其稀土与P,K等矿质元素间亦存在不同程度的相关关系,其中Yb含量与辐照剂量间具有良好的线性关系。更多还原

【Abstract】 The effects of ⁶⁰Co γ-ray irradiation on the contents of rare earth and mineral elements and their relativities in the fruitbodies of Agaricus biazei Murvill and their relativities were studied.The results shows that there are significant difference at the 0.01 level in the contents of rare earth and mineral elements in the fruitbodies among different treatments,and that the variational laws of different elements contents are different with the varieties of the dosages accordingly.The contents of Pr and Mo increase with the increase of the dosage,but they decreases when the dosage are in a certain degree（1.5 KGy）.But the Yb content decreases with the increase of the dosage.The variational laws of the contents of K and Cu are similar along with the variety of the dosage,and they all decrease with the increase of the dosage.But the contents of them increase and are higher than that of the three anterior treatments（0,0.5,1.0 KGy） when the dosage are 1.5 KGy.It can be seen that the contents of rare earth and mineral elements in the fruitbodies have something to do with the dosages at different degrees,and that rare earth also has something to do with mineral elements in different degrees.There is good linear relationship between the content of Yb and the dosage.更多还原
