Abstract

From April to August in 2010, the stem sap flow of two old trees of Cryptomeria fortunei which grow in the National Natural Reserve of Mount Tianmu was continuously detected with the thermal dissipation probe (TDP). The aim of this study was to evaluate the diurnal and seasonal variation of stem sap flow velocity and the change of water consumption of C.fortunei, as well as to analyze how environmental factors were affecting the stem sap flow of C.fortunei. The results showed that, in different season, the diurnal variation of stem sap flow velocity of C.fortunei presented a single-peaked curve, but there were some differences in starting time, peak time and rapid-falling time. The stem sap flow density had a positive relation with photosynthetic active radiation (PAR), air temperature, and vapor pressure deficit (VPD) while a negative relation with relative humidity and CO2 significantly. Both the stem sap flow velocity and average daily water consumption increased with the increase of tree’s diameter, but the stem sap flow density had no such trait. The changes of average daily water consumption of two trees with a diameter of 75.6 cm and 62.8 cm had the same ecological process, the lowest water consumptions were (49.356±14.883) kg and (9.531±4.297) kg in June and the highest were (110.022±21.890)kg and (49.352±2.629)kg in April respectively.
