| Abstract | ||
| A field experiment was applied in college of Agriculture – Kerbala’a University from 17112008 to 1632009 on 3 types of populus cuttings(base , middle and terminal) for 3 length (7 , 14 and 21) cm for each them. The results show that the base cuttings was the best significant in leaf area , root length , fresh roots weight and dry roots weight compared with middle cuttings. Length of cuttings was also significant effect in all studied objectivities , cuttings with length 21cm was the best compared with other treatment in average of leafs number , fresh leafs weight ,dry leafs weight and root length ; while the cuttings with 14cm was given high average of leaf area ; the cuttings with 7cm was given best high average in fresh roots weight and dry roots weight. There was no significant interference between cutting type and length in leafs number , fresh leafs weight and dry leafs weight. Three terminal cuttings have been excluded from the study because of not giving any percentage germination and reason is a lack of carbohydrates accumulated by and encouraging the formation of roots in addition to the exposure with the rest of transactions during the period of the experiment to a sudden drop in temperatures led to a damage and death entirely , therefore the limited research on two types of base and middle cuttings. | ||
