Experience vegetative propagation Russian olive (Elaeagnus angustifolia L.) in Uzbekistan
Аннотация
Conducting the results of the research work on the studies optimal timing of harvesting and planting stem cuttings Russian olive. The formation of adventitious roots on cuttings Russian olive is dependent on callus. The roots are laid in the cambium of the stem cuttings and breaking through the crust near the pillow or sheet between the callus and bark. Cuttings Russian olive autumn harvesting and spring planting at the end of the growing season gave the best gain in height — 166.7±5.35 cm (diameter of 10.2 ± 0.47 mm). Annuals plants from cuttings Russian olive autumn harvesting had 30 cm long and a height of 179.8±5,09 cm (diameter of 11.1 ± 0.69 mm) and save 88%. The best survival was observed in the cuttings, prepared with annual shoots. By the end of vegetative growth leading to escape the majority of seedlings Russian olive reaches 83–166 cm in height. Maximum 160–221 cm.
