Historical Radial Growth of Chinese Torreya Trees and Adaptation to Climate Change

摘要: Chinese Torreya is a vital crop tree with an average life span of thousand years in subtropical China. Plantations this are broadly under construction, to benefit the local economy. Information on growth and adaptation climate change for species limited, but rings might show responses historical dynamics. In study, six stem sections from trees between 60 90 old were acquired analyzed data. The results indicated that accumulated radial increased linearly time, even at age years, increment each ranged 1.9 5.1 mm/year. variances basal area (BAI) correlated precipitation growing seasons. Taylor’s power law was present growth, scaling exponents concentrated within 1.9–2.1. A “Triangle”-shaped relationship found seasons annual increments. Similar patterns also appeared standard index, maximum monthly air temperature minimum temperature. increases highly climate. Slow resilience drought multiple stems one help adapt different conditions, implications plantation management discussed paper.
