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 Greater variability was noted for full-grain seed yield and the number of sterile apex scales.
- 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.
- Recommendation The authors recommend Scots pine for monitoring the state of the female generative sphere.
