Influence of leaf area index on canopy energy partitioning and greenhouse cooling requirements
(2002)
Canopy transpiration, which represents the major cooling process in greenhouses, depends strongly on the crop leaf area index I-LA. In this paper, the influence Of I-LA on canopy and greenhouse energy balance of a soilless ...
Influence of covering material and shading on the spectral distribution of light in greenhouses
(1999)
The solar photon flux distribution was measured in the range from 400 to 1100 nm under a twin-span glasshouse and under the same glasshouse with blanked roof, external shading net and internal aluminized shade-screen. ...
Influence of greenhouse ventilation regime on the microclimate and energy partitioning of a rose canopy during summer conditions
(2001)
The influence of the greenhouse ventilation regime (natural or forced ventilation) on the energy partitioning of a well-watered rose canopy (Rosa hybrida, cv. First Red) was investigated during several summer days in warm ...
Influence of aluminized thermal screens on greenhouse microclimate and night transpiration
(2003)
The aim of this work was to characterize the influence of a thermal screen on: the greenhouse microclimate, energy savings and crop transpiration. Measurements were carried out during winter in a glasshouse cultivated with ...
