สรุป	Dendrochronology is the science of dating and interpreting wood and climate from tree rings. Each annual ring records the tree's growth response to weather during that year: wide rings indicate favorable conditions (adequate water, warmth, light); narrow rings indicate stress (drought, cold, shade). By crossmatching ring-width patterns across trees and backward in time using dead wood, researchers construct chronologies extending centuries to millennia, providing archives of regional precipitation, temperature, and hydroclimate independent of instrumental records.	Palynology is the scientific study of pollen grains and plant spores — microscopic structures that are chemically resistant and preserve well in sediment, soil, peat, ice, and other matrices. In agronomy, palynology is applied to reconstruct past vegetation and land-use histories, monitor crop pollination dynamics, trace the botanical origin of honey, assess aeroallergen loads, and support plant breeding programmes. It bridges botany, ecology, archaeology, and environmental science.
