متن کاملWater-stress-induced xylem embolism in three species of conifers
The mechanism of water-stress-induced xyletn embolism was studied in three species of conifers: Abies balsamca (L.) Mill., Picea rtibens Sarg. and ./uniperus virginiana L. Each species showed a characteristic relationship between xylem tension and the loss of hydraulic conductivity by air etnbolistn. Abies balsamea and Picea rubens began to etnbolize at tensions between 2 and 3 MPa and were com...

Recycled water typically has higher salinity than potable water and therefore may not be an appropriate water source for landscapes planted with salt-intolerant plant species. Coast redwoods (Sequoia sempervirens) are an important agricultural, horticultural and ecological species assumed to be salt intolerant. However, no studies hav...
