“…The seedling form, i.e., the presence of stem or crown abnormalities, is often a decisive factor for a seedling disposal, as it is easily observable and can negatively affect seedling field performance [12,18]. In this study, forked stems occurred more frequently in four month old seedlings grown from acorns treated at 45 • C for 5 h (T4) and stored at 3 • C. This could be associated with the impact of high temperatures on the amount and the rate of transport of auxin and phytohormones which stimulate the orthotropic plant growth [52,53] and thus results in the change of the apical growth morphology.…”

“…Whether it is appraised based on morphological or physiological attributes, or both, seedling quality is closely associated with nursery practices applied during its production and with the quality of the acorn it originated from [11,12,[15][16][17][18]. The latter is determined by the size of the acorn, its weight, viability, moisture content, mineral nutrient reserves, levels of insect and fungus damage and germination [16,[19][20][21][22].…”

To preserve the sustainability of Quercus robur forests, which is at risk due to the disturbed natural regeneration, human assisted sowing of acorns or planting of oak seedlings is often performed. However, the success of these methods depends greatly on the use of high-quality sowing and planting material. Thermotherapy is thus often employed to decrease the acorn mycobiota and maintain their quality during the storage. The aim of this study was to test the impact of acorn thermotherapy, followed by a short-term storage at −1 °C or 3 °C, on the quality of related oak seedlings, which was assessed based on the easily observable morphological characteristics. Height, root collar diameter and seedling form were measured or noted for the 1284 and 1190 seedlings at the age of four months and three years, respectively. It was found that acorn thermotherapy affirmatively affected seedling height, especially at the early growth stage. Positive impact on other seedling attributes could not be decisively confirmed because of the lack of the continuity of the effect (not visible in both younger and older seedlings) and the prevailing impact of other factors. Different acorn thermotherapy conditions (temperature and duration) and short-term storage temperatures appeared to be associated only with the occurrence of stem forking at the earlier stage of seedling growth.

“…During nursery production, saplings are fertilized with mineral fertilizers, which positively affects their quality [29][30][31][32] and capacity for drought tolerance [33][34][35][36]. High-quality saplings have well-developed stems and roots, as well as the optimal concentration of mineral nutrients in the leaves, stems and roots [37,38]. Based on previous experience and knowledge, samplings of higher quality exhibit improved survival and growth when transplanted into natural habitats affected by drought compared to those of lower quality [39,40].…”

The negative impact of drought on plant growth may be modified by the different availability of mineral nutrients and by their adaptation to different local habitat conditions. In this study, we examine the impact of drought, fertilization with phosphorus and provenance, as well as their interactions, on the growth and allometric growth relationships between the belowground and aboveground organs of common beech (Fagus sylvatica L.) and sessile oak (Quercus petraea (Matt.) Liebl.). The research was conducted on saplings originating from two mature mixed stands (dry and wet provenances) dominated by these species. In the common garden experiment, saplings were exposed to regular watering and drought in interaction with moderate and high phosphorus concentrations in the growing substrate (achieved by phosphorus fertilization). The obtained results indicate the negative impact of drought and phosphorus fertilization on the growth of both species. In common beech, a negative impact of phosphorus fertilization on the adaptive capacity to drought was demonstrated by unfavorable ratios between fine root mass and the mass of other organs. The sessile oak provenances under the impact of drought showed a different root collar diameter/stem height increment ratio, which indicates their different phenotypic plasticity as a consequence of adaptation to different frequencies of dry periods in their natural habitats.
