Do microorganisms affect soil?
Nitrite formation by rhizoplane microorganisms of rice seedlings was examined in comparison with that by nonrhizosphere paddy soil microorganisms. Effect of nitrite on root growth of rice seedlings was also investigated under aseptic water culture condition. Rhizoplane microorganisms accumulated much nitrite than the other microorganisms in a root extract medium. The accumulated nitrite maintained a stationary level for more than 2 days. In glucose enriched media, both group of microorganisms accumulated nitrite only temporarily. Formation of lateral roots and root hairs was stimulated in the solution containing 1.12-11.2 ppm NO_2^--N but elongation of primary roots was depressed under 5.6-11.2ppm NO_2^--N concentrations. Growth of rice seedlings was inhibited at concentrations higher than 5.6 ppm. Comparative studies indicated that effect of soil microorganisms on root morphology would have been caused by nitrite produced by rhizoplane microorganisms. Additional Index Words : nitrite formation, rhizoplane microorganisms, rice root, aseptic culture.
Why should preventing measures and biological control methods be preferred for protecting crops?
In plants, disease are caused by microorganisms, and these disease causing microorganisms are called pathogens. Some preventive measures and biological control methods are used to get rid of these pathogens, which are : (a) Simple (b) Economic (c) Minimize pollution without affecting the soil quality.
