Salt stress-induced changes in leaf antioxidant activity, proline and protein content in ‘Shah Anjir’ and ‘Anjir Sabz’ fig seedlings
A major portion of the Iranian fig (Ficus carica) industry is located in high-salinity regions, and salinity is an important limiting factor in the production of this fruit. The present study was conducted to investigate the changes of leaf antioxidant-enzyme activity, proline and total protein content in two fig cultivars with two leaf shapes: ‘Anjir Sabz’ with lobate and palmate leaves, and ‘...

Estimating Vertical Leaf Area Density Profiles of Tree Canopies Using Three-dimensional Portable Lidar Imaging
In this paper, a new method for estimation of vertical leaf area density (LAD) profile of tree canopy using portable scanning lidar is proposed. In this method, which we refer to as the voxel-based canopy profiling (VCP) method, several measurement points surrounding the canopy and optimally inclined laser beams are adopted to facilitate full laser beam illumination of whole canopy up to the in...
متن کامل14 Three-Dimensional Radiative Transfer in Vegetation Canopies
Interaction of photons with a host medium is described by a linear transport equation. This equation has a very simple physical interpretation; it is a mathematical statement of the energy conservation law. In spite of the different physics behind radiation transfer in clouds and vegetation, these media have certain macro and micro-scale features in common. First, both are characterized by stro...
متن کاملChanges of glutamine and asparagine content in cucumber seedlings in response to nitrate stress
Nitrogen fertilizer application rates in intensive agricultural systems have increased dramatically in recent years, especially in protected vegetable production systems. This excessive use of nitrogen fertilizer has resulted in soil secondary salinity, which has become a significant environmental stress for crops such as cucumber, in the protected farmlands. It is thus necessary to illuminate ...
