چکیده
Poplar belongs to the family Salicaeceae, order Salicales and group Amentiflorae (Dickmann and Stuart, 1983; Eckenwalder, 1996). There are 35 species of poplar currently recognized in the world; out of those, 6 Populus species are indigenous to India– P. alba, P. ciliata, P. euphratica, P. gamblei, P. glauca and P. laurifolia, and during past many clones of exotic species of poplar (P. deltoides and P. xuramericana) have been introduced in India in area between 28 o to 31 o N. Poplar have very specialized climatic and edaphic requirements, this is the reason which restrict their cultivation in India (Tewari, 1993).

Effects of Water Stress on Colonization of Poplar Stems and Excised Leaf Disks by Septoria musiva.
ABSTRACT Septoria musiva causes leaf spot and canker diseases of trees in the genus Populus, and is one of the most damaging fungal pathogens of hybrid poplar in eastern North America. The effect of host water stress on Septoria canker development was studied in two separate greenhouse experiments. Hybrid poplar clones NM6, NC11396, and NE308 were stressed by withholding water until predawn wat...
