COMPARATIVE EVALUATION OF HONEYSUCKLE GREEN CUTTING PLANTING PATTERNS IN DIFFERENT TYPES OF GREENHOUSES
The research findings on rooting of softwood honeysuckle cuttings under different planting plans in the structures with full and partial shelter are discussed. The rooting rate in all variants of the experiment was at a high level. The average rooting rate in the structure with partial and full shelter was at the same level - 96.5%. The rooting rate did not change much depending on planting plans and ranged within 96.1% and 96.2%. The average rooting rate of the variety Berel was 97.3%, in the variety Bakcharskiy velikan - 95.7%. In the greenhouse with partial shelter, the maximum average volume of the root system was amounted to 4.3 cm3. In a greenhouse with full shelter, the maximum average volume of the root system was 5.4 cm3. The average diameter of the stem in the variety Berel was 3.2 mm, in the variety Bakcharsky velikan - 3.1 mm. There were no differences in factor A; the diameter of the stem was 3.7 mm in each variant. The maximum diameter of the stem was found in the planting plan of 7 × 5 cm - 3.8 mm. The research findings showed that planting diagrams did not significantly affect the rooting of cuttings and the biometric indices of seedlings, but at the same time at compact planting (with a diagram of 5 × 3 cm) more cuttings were placed per square meter (up to 660 pcs m2) that the economic effect in this option from an area unit would be higher.
