查询词典 tolerance factor

It is an ancient species in its own genus and well-adapted to drought environments with fissurate growth and summer dormancy. Methods We selected Dengkou as our research site and collected three stages of P. mongolica (before, during and after fissuration) during August 1-5, 2002 and 2003. We used PV technique and measured several water relations parameters (φ,φ, ROWC, RWC,△(subscript φ),ε etc. in different stages of fissurate growth for comparison and analysis of drought tolerance and its mechanisms. Important findings Different stages of P. mongolica had different abilities and pathways to maintain turgor pressure. Fissurate growth decreased the species' drought tolerance and involved multiple adaptations to drought.
