Factors Influencing the Distribution of The Fungi on Plant Roots.

By J. E. C. Aberdeen

 

In the article was mainly discussed about the application of frequencies that has been applied to quantitative estimation of fungi on plant roots. This research also has been studied about the incidence of fungi that associated in the plant roots and their relationship to the rhizosphere. This qualitative is approaches before where they use to indicate the broad differences between rhizophore and soil. There are five method that can be used to present a demonstration on quantitative relationship of rhizophores and rhizoplane. One of them based on dilution and use of various types of media, and then it will modify them to be less selective or non-selective. The methods that have been used in this study, firstly, ecological and sampling techniques. This method need to prepare the roots portions in the plate and run it under high temperature. So that, the showed result of the present or absent of the fungus species at the plate is used to estimate frequency percentages. The mathematical modification is used towards this method to make sure that it will more practicable. Second method that used in this study is cultural method. The trials of the roots are experimental in the plate and left for a few days in incubator. Over the period of the experiment, the trials need to expose to the sunlight. This method probably to establish the fact of the differences in distribution existed and also to dissect out the factor causing the differences. The result of this research shows the root community in a few conditions such as in glasshouse and field. So, the result clearly showed the distribution of fungi on the roots is higher based on two factors which is host plant and the associated fungi. At the last of the article, the writer mentioned that the overall influence of host plant on fungus population of the rhizoplane has been demonstrated before. Although that, there are no attempt to analyse these interaction in further.
