概要 Root images of cucumber plants were digitized for computation. The computed image was used for analysis of elongation and branching of the roots grown in different O_2 levels in nutrient solution. The... branching structure of root system was affected by O_2 level: Lower O_2 concentration resulted in inhibition of elongation of the second-order roots and in development of many branching of the third- and the fourth-order roots. However, the effect of O_2 level in the solution on top growth was scarcely found. From the results, it could be conceivable that root system develops with increase in branching roots to maintain physiological function in plants for adaptation to the root environment which is not optimalized.続きを見る
