e0“Evaluation of the manifestation of Scots pine trees reaction to the weakening effect of Heterobasidion annosum (Fr.) Bref”
e1“Over the three-year period 2017-2019 the weighted average tree health category in the sample area increased from 2.21 to 2.52. The morphometric parameters of cones turned out to be more stable in the female generative sphere. Greater variability was noted for full-grain seed yield and the number of sterile apex scales”

Other claims from this paper (9)
- Observation The weighted average tree health category of Scots pine in the sample area increased from 2.21 to 2.52 over 2017-2019.
- Observation Morphometric parameters of cones were more stable than other traits in the female generative sphere.
- Observation Relatively high preservation of seed ovules was found across the developmental periods, at 70.60-81.77% and 79.07-88.35%.
- Observation The pollination quality was sufficient and male and female genotypes were markedly compatible, as indicated by the ovule preservation values.
- Observation Embryo survival in the experiment reached 63.44-81.48%.
- Association The generative sphere of Scots pine was sensitive to the stress caused by Heterobasidion annosum disease development.
- Association Infected trees with weakening and dying out showed a significant decrease in the average length and diameter of mature cones.
- Association Infected trees with weakening and dying out showed a relative increase in female reproduction rates.
- Recommendation The authors recommend Scots pine for monitoring the state of the female generative sphere.
