Importance of Poplar wood Consumptions are attended in different industerials. Therefore, extensive culture of poplar has customaried by people and department of natural resources in Guilan province for afforestation. It is need to provide Voulume Table of poplars. So a design of volume table found out at the Safrabaste poplar research station in 1364. Number 2992 Single root of 8 clones of successful poplar planted on surface equal 5 hectars. Evrey year high and diameter (breast high) of trees measured and 10 single root among them which arrived to diametric class. Thay were cut and finding volume. Finaly, volume table trees have done on base volume and weight increment. Volume increment was measured on different diametric class that it started from 6cm and ended 22 to 27cm. For every clones drawed relations and correlation between studied quantities. The result one of clones, like: Populus deltoides. 69/55 with correltion coefficient 97%, volum increment in the downest and the highest diametric class were respectively 0/075 and 0/462(m3), and it's equation with two factors is : V=0/00002 d2h+%7 At last, for other studied clones have got in different diametric class. Keywords : volumetable, poplar, clone, safrabaste
