Inoculation with an endomyeorrhizal fungus (Glomus sp.CC-1)on roots of sunki (Citrus reticulata) and trifoliata orange (Poncirus trifoliata),which are the most useful rootstocks of Citrus in our country,was carried out in pot experiments.The soil used was an nutrient poor especial phosphate deficient red earth,sterilized by autoclave.

Inoculation with an endomyeorrhizal fungus (Glomus sp.CC-1)on roots of sunki (Citrus reticulata) and trifoliata orange (Poncirus trifoliata),which are the most useful rootstocks of Citrus in our country,was carried out in pot experiments.The soil used was an nutrient poor especial phosphate deficient red earth,sterilized by autoclave. Seedlings of either species were dealt with four treatments,including soluble and inso- luble phosphate fertilizer application and with or without mycorrhizal inoculation.Each treatment was replicated three pots,consisting of 9 seedlings.Both phosphate fertilizers were labelled with radioactive isotope ~(32)P to examine the absorption of phosphorus by Citrus plants. The present study was undertaken to determine the effects of mycorrhizal infection on P uptake by Citrus seedlings.Microautoradiographs clearly showed that ~(32)P was ta- ken up by hyphae of mycorrhizal fungus and was accumulated in arbuscles and vesicles, inside the roots.Macro-autoradiograph demonstrated that ~(32)P was translocated in shoots of mycorrhizal seedlings much more than it was in nonmycorrhizal seedlings.Phosphorus analysis and seediling growth response indicated that endomycorrhizae increased phos- phate absorption from fertilizer and from soil as well.

接种一种球囊霉 Glomus sp.编号 CC-1于红壤中,使酸桔和枳实生苗的根系感染形成泡囊丛枝内生菌根。应用放射性同位素~(32)P 标记的可溶性磷肥和难溶性磷肥来研究菌根真菌对柑桔吸收磷肥的作用。放射性宏观自显影和显微自显影表明菌根真菌加强了柑桔对两类磷肥的吸收。放射性测量和化学分析证明有菌根柑桔实生苗的地上部含磷量以及从红壤中和从肥料中吸收的磷量比无菌根的增多,有菌根实生苗的生长反应也较好。

Inoculation of Sunn Crotalaria seedlings with VA mycorrhizal fungi(Glomus epigaeus)greatly increased the plant height,dry weight production and uptake of phosphorus,zinc and copper by the host plant.Particularly,inoculation with both VAM and Rhizobium showed the most favourable effects on the increasing of biomass and uptake of Zn and Cu.Inoculation with VAM also caused the blooming period to occur about one month earlier,compared with the non-inoculated plant.The application of zincous nutrients also...

Inoculation of Sunn Crotalaria seedlings with VA mycorrhizal fungi(Glomus epigaeus)greatly increased the plant height,dry weight production and uptake of phosphorus,zinc and copper by the host plant.Particularly,inoculation with both VAM and Rhizobium showed the most favourable effects on the increasing of biomass and uptake of Zn and Cu.Inoculation with VAM also caused the blooming period to occur about one month earlier,compared with the non-inoculated plant.The application of zincous nutrients also influenced the height growth and biomass of Sunn Crotalaria.In this experiment,the intermediate concentration of zinc sulfate,that is 30 ppm ZnSO_4,was the most effective for the growth of Sunn Crotalaria,as well as for the colonization and development of Glomus epigaeus.Natural infection of Crotalaria seedlings by the aboriginal VAM produced a smaller percentage of infection and of intensity of root colonization. The effects of infection by the aboriginal VAM on the host plant appeared much later than the effects of artificial inoculation with Gl.epigaeus.

用 VA 菌根真菌 Glomus cpigaeus、柽麻根瘤菌 Rhizobium sp.和五种不同施锌浓度对柽麻进行盆栽试验,结果表明,凡是接种 VA 菌根的柽麻,其高生长、干物质重,以及对 P、Cu 和 Zn 的吸收,增加都极显著。特别是在干物质重和 Zn、Cu 等微量元素的吸收方面,菌根和根瘤菌双接种效果尤佳。不同施锌浓度对柽麻的高生长和生物量也有影响。施锌浓度中等(30ppm)时效果较好,施锌浓度高时(90ppm),柽麻的高生长、干物质重以及对锌的吸收均下降。接种VA 菌根能使柽麻提早开花。人工接种 Gl.epigaeus 对柽麻根部感染较快,感染率和感染强度也高。自然感染 VA 菌根的柽麻感染过程较慢。VA 菌根对寄主植物所起的促进作用也较迟。不同接种处理和不同施锌浓度对柽麻地上部分的 N、K、Ca和 Mg 的含量影响不规则。

The direct role of VA myeorrhizal hyphae in P and Cu uptake and transport were studied in the present experiment. White clover plants were grown in a calcareous soil in pots with three compartments, a central one for root growth and two outer ones for the growth of mycorrhizal hyphae. Phosphorus was applied to the soil at three levels (0, 20 and 50 mg/kg) in the outer compartments in mycorrhizal treatments. Two types of control treatments were used, one having comparable mycorrhizai infection but...

The direct role of VA myeorrhizal hyphae in P and Cu uptake and transport were studied in the present experiment. White clover plants were grown in a calcareous soil in pots with three compartments, a central one for root growth and two outer ones for the growth of mycorrhizal hyphae. Phosphorus was applied to the soil at three levels (0, 20 and 50 mg/kg) in the outer compartments in mycorrhizal treatments. Two types of control treatments were used, one having comparable mycorrhizai infection but no access to the outer compartments, the other not being mycorrhizal but well fertilized with P. Plant dry weight was increased in mycorrhizal treatments with hyphal access to the hyphai compartments Both concentration and amount of P in roots and shoots were apparently increased as the P level in the outer compartments increased. Accordingly, the calculated delivery of P by the hyphae from the outer compartments was greatly increased.Hyphal access to the outer 'compartments also significantly increased the concentration and amount of Cu in roots and shoots, irrespective of the P levels and the amount of P taken up by the hyphae. However, the distribution of Cu between roots and shoots was largely dependent on the P levels applied to the outer compartments.

利用隔网分室盆栽方法,将土壤分为根系吸收区和菌丝吸收区,以白三叶草为供试作物,定量测定了VA菌根菌丝对土壤磷和铜的吸收量及其在植物体内的分布。结果表明,菌根的侵染显著提高了植物对磷和铜的吸收。但提高的程度受菌丝生长区供磷水平的影响。施磷水平提高,菌丝吸磷量明显增加,磷在地上部和根中的分布趋势一致。铜则不同,随施磷量的增加,地上部菌丝贡献率上升,而根中贡献率下降,菌丝吸铜总量也呈下降趋势。说明,菌丝对铜的吸收和运输与磷无密切关系。然而,铜从根部向地上部的运输受植物磷营养状况的影响。
