The study of the effects of soil and environment condition on Copressos macrocarpa rhizogenesis

Cupressus macrocarpa or Monterey cypress grows on the south, northwest of Americ aand California. Monterey: Cypress is an evergreen conifer that can get over 100 ft (30 m)tall with a trunkdiameter of 8 ft (2.4 m). Besides the wood prod uct, gardners use thisspecies with brunch praning. Recent decades flower producers imported this species to Iran. Cutting method is the most suitable method of reproducing of this tree. To increas the sapling prod uction in one area different places and soil componets with split plot method were used, there were 3main treatments for space production: 1-green house without temperature with 2 meter height 2- green house without temperature with 1 meter height 3- open space. In Secodary treatment there were four kinds of soil such as: (sand, loam, 2 1 lome+ 2 1 mold + 3 1 sand + 3 1 mold + 3 1 forestsoil) in every flowerpot 10 * 7 cm two cutting hemi wood placed. In every method (space production) 240 flowerpot with 480 cutting and in three methods 720 flowerpot and 1440 cutting at the end of septe mber was provided. After twelve month results showed that in main treatment (production space) at 5% and secondary treatment (different soil componets) 1% was significant. The most persent rhizogencsis was related to main treatment 54.15% and secondary treatment 54% and the least percent was related to open space (22.2%), and sand (16.4%).
