The effect of Trifluralin on the formation of ectotrophic mycorrhizae in some pine species I. Toxicity to mycorrhiza forming fungi     

Ch. Iloba 《Forest Pathology》1977,7(1):47-51

Laboratory experiments were conducted to test the effect of various concentrations of Trifluralin on certain fungi. The ectotrophic mycorrhizal fungi tested were: Amanita citrina Schaefer, Tricholoma pessundatum (Fr.) Quel., and Tricholoma saponaceum (Fr.) Qtiel. All exhibited sensitivity to Trifluralin concentrations. The consequence of such fungitoxicity was discussed.  相似文献   

The effect of Trifluralin on the formation of ectotrophic mycorrhizae in some pine species     

Ch. Iloba 《Forest Pathology》1977,7(3):172-177

Pot experiments were performed to investigate the effects of Tritluralin on the mycorrhizal symbiosis of conifer seedlings. Infected forcst soils and potting mixturcs were mixed, pottcd and treated with Trifluralin at levels of 0.2 and 0.4ml/m² Seeds of Pinus sylvestris L. and Picea abies (L.) Karst. were sown in the pots. The concentrations tested, though recommended by the manufacturer produced phytotoxicity. The seedling growth in general and that of the rootsystem and laceral roots in particular, were severely inhibited. Mycorrhizal development in the seedlings was consequently adversely affected.  相似文献   

Aspect of herbicidal effects on the ectosymbiotic microorganism of the forest plants     

Chukwunyeaka Iloba 《Forest Pathology》1975,5(6):339-343

Experiments were conducted under laboratory conditions to establish the sensitivity or otherwise of the following mycorrhizal fungi: Tricholoma saponaceum (Fr.) Quel., Tricholoma pessundatum (Fr.) Quel. and Amanita citrina Schaefer to the herbicides Dalapon and Aminotriazole. Various reactions were shown by the fungi. In general, the rareness of growth stimulation coupled with significant inhibition of mycelial growth are indications of the fungitoxicity of the herbicides.  相似文献   

The effects of some herbicides on the development of ectotrophic mycorrhiza of Pinus sylvestris L.     

Ch. Iloba 《Forest Pathology》1976,6(5):312-318

Pot experiments were carried out to investigate the real effects of Dalapon and Amionotriazole herbicides on the development of mycorrhiza in seedlings of P. sylvestris. Despite their different toxicity, both adversely affected mycotrophy, confirming their toxic tendency shown in earlier in vitro experiments. It is consequently suggested that much consideration should be given to choice of herbicides, as mycorrhiza forming fungi, as well as ectotrophic mycorrhizae, are sensitive to these toxicants.  相似文献
