e0“Evaluation of the manifestation of Scots pine trees reaction to the weakening effect of Heterobasidion annosum (Fr.) Bref”
e2“Relatively high preservation of seed ovules was found in the first and second vegetative periods of development within the boundaries of average values. For trees of different status categories during the whole period of observations it was 70.60-81.77 and 79.07-88.35% respectively, which indicated sufficient quality of pollination and marked compatibility of male and female genotypes”

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 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.
