Tree growth has been hypothesized to provide a reliable indicator of the state of the external environment. Elevated levels of background ionizing radiation may impair growth trajectories of trees by reducing the annual growth. Such effects of radiation may depend on the individual phenotype and interact with other environmental factors such as temperature and drought. We used standardized growth...
Altitudinal variation in morphological, physiological and biochemical characteristics between two provenances of Abies faxoniana Rehd. et Wils. from contrasting elevations (3,500 and 2,850 m) was investigated by reciprocal transplantations in the eastern Qinghai-Tibetan Plateau. From each altitude, 54 seedlings were selected, of which 27 seedlings were simply transplanted at their original altitude,...
This study was carried out to evaluate the effect of N, P, and K on the growth of Caesalpinia echinata plants and on the anatomical and chemical characteristics of their stems. Eight-month-old plants were grown in polyethylene pots of 8 L containing soil. The pots were arranged in randomized blocks where they received N, P, and K in isolated form, and NPK combined in 10:10:10 and 04:14:08 ratios....
