Abstract

1) In the presFent paper, the writers described the results of investigations on the starch accumulation in the area surrounding the spots on the leaves of rice plants affected by Cochliobolus miyabeanus.
2) After the inoculation, the starch disappeared in the area around the spots within 20 hours and then it began to accumulate in the area surrounding the zone where starch disappeared. The starch accumulation increased with the development of spotted area. After several days, the value of starch accumulation index, the ratio of area of starch accumulation to the spotted area, became constant, while the concentration of starch continued to increase. It seems that the effect of infection gives rise to some abnormal physiological changes in the host immediately after the invasion of parasite.
3) The area of starch accumulation was small in the early morning, but increased rapidly with the increase of insolation and remained constant until the sunset, while the concentration increased markedly in the evening. Under rainy or cloudy weather, starch decreased or disappeared around the spot. By keeping plants in a dark place for 24 hours, the starch disappeared. However, in some samples collected on the 10 th day after the inoculation, starch was still detectable.
4) In plants cultured with nutrient solution containing excess amount of manganese or decreased amount of nitrogen and also in Akiochi plants (rice plants physiologically declined in autumn), the starch accumulation was promoted. Generally, it seems that in the surrounding zone of spots revealed on plants grown under abnormal nutritional condition, starch accumulates greatly.
5) Judging from the results of our experiments, it may be suggested that the accumulated starch around the spotted area is assimilatory, and that the mechanism of this abnormal starch accumulation is partially based on the increased activity of starch assimilating enzymes, e. g. phosphorylase etc., in the surrounding area of spot.
