Abstract
The author studied the effect of the foliar application of urea on the microflora of the wheat root surface in relation to time. The effect of this treatment was manifested in the dry weight of the roots and in the parts above the ground seven days after application. The number of bacteria on the plants increased markedly on the first days after application, while the number of fungi showed a pronounced decrease. In time the differences were equalized. Bacteria requiring amino acids and growth factors predominated on the roots of treated plants, while the main fungi were members of the genusFusarium and in the control plants members of the genusPenicillium.
Abstract
Исследовалось действие внекорневой подкормки на микрофлору поверхности корней пшеницы мочевины. Подобная обработка растений проявлялась в сухом веществе корней и наземных частей 7 дней после обработки растений: в первые дни после начала опыта количество бактерий у растений выраженно повышалось, тогда как количество грибков значительно понижалось. С течением времени эта разница стиралась. На корнях обработанных мочевиной растений преобладали бактерии, нуждающиеся в аминокислотах и факторах роста, в то время как у грибов преобладали представители рода Fusarium, тогда как у контрольных растений—Penicillium.
