Abstract:
The article presents the results of scientific research on seed propagation and cultivation of
seedlings of native species of barberry – oblong barberry (B. oblonga), monetary barberry (B.
nummularia) and integrifolious barberry (B. integgerima), common in the flora of Uzbekistan.
Sowing the oblong barberry seeds in November, collected in early September and stratified for
68 days, showed 14,9% germination, the highest indication in spring was observed in the seeds
collected in the second half of September and sown in freshly-harvested form, their germination
rate was 27,4%. At the same time, the gross yield of seedlings from 1 hectare of nursery
amounted to 850, 0 thousand pieces, out of which 94,6% are standard ones. Sowing the seeds of
integrifolious barberry in November that were collected at the end of September, during the
period of full ripeness of the fruits and stratified for 47 days, showed 42,4% of soil germination
and provided a gross yield of seedlings of 1066,6 thousand pcs/ ha out of which 93,1% are
standard seedlings. Monetary barberry seeds collected at the end of September and sown in the
fall after 47 days of stratification, provided the highest rate of soil germination in spring –
42,4%, which ensured a gross yield of seedlings in the amount of 1483 thousand pcs/ ha and
94,7% of them are standard seedlings |
