| 中文摘要: |
| 为了探讨不同浓度的镉对姬松茸子实体农艺性状、显微结构及部分矿物质元素吸收的影响，在培养料中添加不同浓度的外源镉进行出菇试验，研究了姬松茸子实体农艺性状、显微结构及部分矿物质元素含量的变化规律。结果表明：随着添加镉浓度的增加，柄量、柄直径、盖重、盖直径、朵重等农艺性状先增加后减小；子实体孢子和囊状体大小也是先增加后减小；子实体中锌含量逐渐降低，铜和铁的含量均先增加后降低，但是含量均高于对照，钙、镁的含量均先降低后增加。低浓度镉（<2.5 mg·kg-1）促进农艺性状，而高浓度镉（>2.5 mg·kg-1）抑制农艺性状，镉通过影响农艺性状影响产量；低浓度镉（<2 mg·kg-1）能促进子实体孢子和囊状体的生长，而高浓度镉（>2 mg·kg-1）对孢子和囊状体有毒害作用；镉对锌的吸收具有抑制作用，能促进铜和铁的吸收，低浓度镉抑制钙、镁的吸收，而高浓度镉促进钙、镁的吸收。 |
| 英文摘要: |
| The effects of different concentrations of cadmium on the agronomic traits, microstructure and absorption of some mineral elements of fruiting bodies were studied by adding cadmium(Cd) in the culture medium. The results showed that, with the increase of Cd concentration in the culture medium, agronomic traits, such as the average weight per pileus, per stalk and per fruit body, the average diameter per stalk and per pileus, and so on, increased first and then decreased, indicating that lower concentrations of Cd(<2.5 mg·kg-1) could promote agronomic traits, that higher concentrations of Cd could inhibited agronomic traits, and that Cd could affect yield by influencing agronomic traits. Low concentration of Cd(<2 mg·kg-1) could promote the growth of spores and cystidium, while high concentrations of cadmium(>2 mg·kg-1) had toxic effects on spores and cystidium. Cd in different concentrations could inhibit the absorption of zinc(Zn), but promote the absorption of copper(Cu) and iron(Fe). Low concentration of Cd could inhibit absorption calcium(Ca) and magnesium(Mg), and high concentrations of cadmium could promote absorption of Ca and Mg. |
