Orchards and many other land surface types have vegetation that does not completely cover the underlying ground surface. For these land surfaces there are at least two distinct and interacting surface components, the overstorey/canopy and the underst

We present an improved method for calculating transpiration from an apple tree using the Penman-Monteith equation, based on an improved calculation of the effective stomatal resistance for the whole tree. The calculation has two parts: (1) calculatin

Measurements were made of the effect of a reflective ground covering on the absorption of radiant energy by an apple tree ( Malus domestica Borkh . ‘Splendour’) in an orchard. Total absorbed PAR and net all-wave radiation were measured using the

Many models that describe the energy balance of plant canopies are unsuitable for use as components of larger-scale climate models because their computational and data input requirements are too large. Models based on ‘higher-order-closure’ and L

In outdoor experiments a temperature sensor is always subjected to a radiation load that results in a temperature excess error. Not only the mean temperature is effected by this radiation load but also, for a fast-responding sensor, the measured temp

In this paper we describe a device for measuring total radiation absorbed by the canopy of a single tree. The net influx of all-wave and photosynthetically active radiation (PAR) are found by integrating measurements over a sphere enclosing the tree.

This paper describes measurements of the architecture of a kiwifruit canopy grown on a pergola. The orientation of the leaves was analysed in terms of their inclination and azimuth angles. The mean leaf inclination was 33° from the horizontal and th

In an earlier treatment, we used the concept of coupling between vegetation and the atmosphere to demonstrate how the sensitivity of transpiration to a change in stomatal conductance decreases as the spatial scale increases from leaf to region. We in
