| transpiration efficiency of a tropical pioneer tree (ficus insipida) in relation to soil fertility. | the response of whole-plant water-use efficiency, termed transpiration efficiency (te), to variation in soil fertility was assessed in a tropical pioneer tree, ficus insipida willd. measurements of stable isotope ratios (delta(13)c, delta(18)o, delta(15)n), elemental concentrations (c, n, p), plant growth, instantaneous leaf gas exchange, and whole-plant water use were used to analyse the mechanisms controlling te. plants were grown individually in 19 l pots with non-limiting soil moisture. soil ... | 2007 | 18057036 |
| heat dissipation sensors of variable length for the measurement of sap flow in trees with deep sapwood. | robust thermal dissipation sensors of variable length (3 to 30 cm) were developed to overcome limitations to the measurement of radial profiles of sap flow in large-diameter tropical trees with deep sapwood. the effective measuring length of the custom-made sensors was reduced to 1 cm at the tip of a thermally nonconducting shaft, thereby minimizing the influence of nonuniform sap flux density profiles across the sapwood. sap flow was measured at different depths and circumferential positions in ... | 2002 | 11874724 |
