The relationship between water and
plant productivity is extremely complex. Plants exhibit broad range of
adaptations to either excesses or deficits of water. These adaptations permit
life to continue in almost any type of water condition that can be found on the
earth. However, for each species; there is a rather limited range of moisture
conditions that can be tolerated, and water factor is a major determinant of
plant distribution. Water excesses such as flooding has effects on survival and
growth of plants. The social and economical losses caused by drought and
flooding stress are appreciable. Flooding caused decreased in branch length
increment and the number of leaves of P. alba saplings, however height and
diameter increment were not reduced. Flooding induced significant decrease in
gross photosynthetic rate (Pg,max) and chlorophyll fluorescence
yield of P. alba saplings. The
formations of adventitious roots were observed in P. alba saplings.
