În presented article some suggestions about the need for systemic approximation for the implementation of classical and modern methods in forestry are exposed. This will improve the rational use of oak species in reforestation and contribute to sustainable development of the forestry sector. Among these methods, of major importance in afforestation practice are those that reveal the necessity to take into account the acorn origin and sowing period. Their correct choice influences the rate of seedling growth speed and their capacity to adapt to stressors. To ensure the genetic variability of offspring, the collection of acorns from maternal trees with different leafing periods in the spring is recommended. In afforestation works is also necessary to consider the degree of seedlings shading, which can influence both, the growth rate, and the ratio between organs sizes of tree. For elucidating the physiological state, tolerance, and adaptive capacity of oak trees to biotic and abiotic stress factors, using of the methods of electrolyte leakage and chlorophyll fluorescence in combination with application of different doses of heat shock, separately, and in two fractions is recommended. The effectiveness of mentioned procedures and methods was demonstrated practically by determining the physiological status of various oak species during different
seasons of the year and initiating new plantations of oak with descendents of different origin, installed in the Center and South of the Republic of Moldova. |
