EFFECT OF SADH AND CEPA ON ELONGATION GROWTH AND ANATOMICAL STRUCTURE OF APPLE STEM |
| Author: | F. Jaumien |
| Abstract:
SADH alone or mixed with CEPA, applied as a single spray, significantly inhibited elongation growth of apple tree shoots. A mixture of SADH (1 000 ppm) and CEPA (250 pmm) retarded growth of apple shoots to the same or to an even greater extent, as compared with SADH alone at a double concentration (2 000 pmm). The unsprayed, vigorously growing shoots differed in structure from shoots with inhibited growth. In the upper part of the retardant - sprayed shoots, the cortex widened and the development of secondary xylem was weakened. | |
