Abstract: Low availability of inorganic phosphorus (P) is considered a major constraint for crop productivity worldwide. A unique set of 266 chickpea (Cicer arietinum L.) genotypes, originating from 29 countries and with diverse genetic background, were used to study P-use efficiency. Plants were grown in pots containing sterilized river sand supplied with P at a rate of 10 μg P g soil as FePO , a poorly soluble form of P. The results showed large genotypic variation in plant growth, shoot P content, physiological P-use… Show more

“…Using the leaf transpiration rate data measured on the youngest fully expanded leaves from Pang et al . (), there was a weak correlation between the concentration of Mn in mature leaves and leaf transpiration rate ( r = 0.28, P < 0.01) (Table ; Fig. ).…”

“…For example, our results show a weak but significant correlation between foliar Mn concentration and root size including total root length, root surface area and root hair cylinder volume, but the correlation was much weaker than that with carboxylates. Likewise, a weak but significant correlation between foliar Mn concentration and leaf transpiration also was found in this study, but this correlation was much weaker than the correlation between leaf P concentration and leaf transpiration rate ( r = 0.57, P < 0.001) measured on the same plants of 100 chickpea genotypes (Pang et al ., ). Therefore, although we suggest using Mn as a proxy for belowground carboxylate exudation process, we should not ignore the role of leaf transpiration and root size in Mn accumulation.…”
