Abstract:
The article presents the results of studies on the results of the introduction of common cranberry
in the conditions of the Botanical Garden of the Academy of Sciences of Uzbekistan. The results
of studies on the morphological and decorative features of leaves, flowers and fruits of
Viburnum under introduction conditions are presented. The possibilities of seed and vegetative
propagation are studied. Seeds after extraction from berries immediately undergo stratification
within 90-100 days. Sowing is carried out in late November or early December. The seeding rate
of 20 g/m2 or 400 seeds per square meter. Seeding depth is 2-3 cm. Seed germination and
emergence are observed in April. The best result of soil germination of seeds (68%) was noted in
the variant of collecting seeds on September 10 and their sowing after 85 days stratified. In this
version of the experiment, 272 seedlings appeared in each square meter. The worst result was
shown by seeds harvested on October 25 and sown after 43 days of stratification - 7%. Lignified
stem cuttings of Viburnum harvested 11.03 rooted at 68%, the safety of seedlings at the end of
the growing season was 95.4%. The output of seedlings from 1 square meter was 64 pieces, from
1 hectare of the nursery 448 thousand pieces. The second year, seedlings grow more intensively;
they have a height of 90-130 cm at the end of the growing season |
