In filicophytes, there was a relatively high ratio of VA mycotrophy in the eusporangiates, and there was no autotrophic in the eusporangiates; but the ratio of autotrophic was up to 71%, and the ratioes of VA mycotrophic and facultative mycotrophic were low, 15% and 14% respectively in the leptosporangiates.

用碱解离、酸性品红染色法对云南热带、亚热带自然生长和部分移栽到温室中的256种(拟蕨类植物20种,真蕨类植物236种)蕨类植物孢子体的VA菌根状况进行了调查研究,结果发现,在拟蕨类植物中,孢子体只存在兼性VA菌根营养和自养两种菌根营养类型,两种类型,两种类型所占的比例相当;在真蕨类植物中,厚囊蕨类植物VA菌根营养的比例较高(92%),且无自养类型;而在薄囊蕨类植物中,自养型占71%,VA菌根营养和兼性菌根营养所占的比例都不高,分别是15%和14%。

But after about a month to restore the root system, the leaves of nitrogen, phosphorus and potassium contents in treatment 5, 6, 7, 8, 2 gradually higher than the control. This is because the absorption of fertilizer during this period shown to promote on the elements, and with the passage of time the processing elements continue to be reduced to a leaf until the latter part of the growing season is also higher than the control.3.The pH value in rhizosphere soil of treatments poplar plantation were lower than that in non-rhizosphere soil, but the content of organic,available nitrogen, phosphorus, potassium, utility cuprum and utility zincum were all higher than those in non-rhizosphere soil.

但是经过大约一个月的根系恢复,处理5、处理6、处理7、处理8、处理2叶片中的N、P、K逐渐高于对照,这是因为施肥对元素的吸收在这一期间开始表现出了促进作用,并且随着时间的推移各处理中元素含量持续降低至落叶,直至后期的生长季节也高于对照。3、各处理的杨树林地根际土壤pH值均低于非根际土壤,而有机质、碱解氮、速效磷、速效钾、有效铜和有效锌的含量均高于非根际土壤,与其它处理相比,80cm两侧断根施肥处理的根际土和非根际土壤速效养分含量最高,差异达显著水平。

Label with LC-Red640 and LC-Red750 two are aimed at above all 112 code with 158 child detect 5 ′ carry bougie, corresponding anchor decides bougie to be labelled by fluorescence in 3 ′ end, circulate quickly from inside DNA of person gene group again PCR is distinctive the enlarge that make thing adds part of ApoE gene 265bP and with distinctive bougie cross hind, cause fluorescent resonance energy to transfer, the occurrence that passes different source cross and fault match alkaline base the fusible parameter of the type will finish feral model divide with choppy gene model.

首先以LC-Red640和LC-Red750标记两条针对112和158位编码子的检测探针5′端,相应的锚定探针在3′端被荧光标记,再从人基因组DNA中快速循环PCR特异引物扩增apoE基因265bP片段并和特异探针杂交后,引发荧光共振能量转移,通过异源杂交的出现和错配碱基的类型的熔解参数来完成野生型和突变基因分型。
