“…The PM equation aggregated to sub-model for both LAI and r s has been successfully applied at all scales, from single leaves to whole canopies (Stanghellini, 1987;Bailey, 1993), and for a www.intechopen.com wide range of horticultural crops (e.g. Yang et al, 1990;Pollet et al, 1999;Montero et al, 2001;Rouphael & Colla, 2004).

“…Both the relative proportion and the uptake activity of the highly absorptive, apical young root segments decreased through plant maturity (with concurrently increasing ratio of old roots mainly responsible for transport), resulting in the continuously reducing water uptake of the whole root system (Gao et al, 1998;Lai and Katul, 2000). Considerable reduction in transpiration rate per leaf surface area was also observed in crop plants during the late generative phase of ontogeny (Medrano et al, 2005;Yang et al, 1990).…”

“…Plant transpiration was estimated by subtracting pumice evaporation from evapotranspiration derived from the planted pots. Calculated daily transpiration (DT) values were regarded as daily root water uptake (Lai and Katul, 2000;Nomiyama et al, 2013), as biomass increment could be ignored for relative comparison of the results (Yang et al, 1990). Water uptake was expressed in the form of 5-day moving average of daily transpiration (DT) data.…”

A b s t r a c t. Pot experiments were designed to test the applicability of root electrical capacitance measurement for in situ monitoring of root water uptake activity by growing cucumber and bean cultivars in a growth chamber. Half of the plants were inoculated with Funneliformis mosseae arbuscular mycorrhizal fungi, while the other half served as non-infected controls. Root electrical capacitance and daily transpiration were monitored during the whole plant ontogeny. Phenology-dependent changes of daily transpiration (related to root water uptake) and root electrical capacitance proved to be similar as they showed upward trends from seedling emergence to the beginning of flowering stage, and thereafter decreased continuously during fruit setting. A few days after arbuscular mycorrhizal fungi-colonization, daily transpiration and root electrical capacitance of infected plants became significantly higher than those of non-infected counterparts, and the relative increment of the measured parameters was greater for the more highly mycorrhizal-dependent bean cultivar compared to that of cucumber. Arbuscular mycorrhizal fungi colonization caused 29 and 69% relative increment in shoot dry mass for cucumbers and beans, respectively. Mycorrhization resulted in 37% increase in root dry mass for beans, but no significant difference was observed for cucumbers. Results indicate the potential of root electrical capacitance measurements for monitoring the changes and differences of root water uptake rate.K e y w o r d s: mycorrhiza, phenology, root electrical capacitance, transpiration, water uptake INTRODUCTION

“…Furthermore, transpiration is directly related to plant production (Watts and Goltz 1985) and merely 1.0% of the water taken by plants is utilized in metabolic activities (Rosenberg et al, 1983).
