بررسی تاثیر ازت و فسفر بر روی رشد و نمو و نیز توسعه کانالهای صمغ و میزان و ترکیبات آن در نهالهای بنه

‭Natural gum and resins which are extracted from some known plants such as coniferous, pistachios and prune species, are very important in resinous, cosmetics, insecticides and so force industries. In the way of extraction, there are working problems with mature and large trees as well as degeneration the trees when gum extraction is repeated for years. Gum and resin trees reserve these materials for defending against insect bites and bacterial and virus injuries. In this research was tried to estimate the possibility to resin extraction from one year old seedlings of Pistacia atlantica subsp. mutic(banah). Resin ducts were studied in root, shoot and leaf by picking the one-year organ sampling. Samples were fixed with FAA fluid and kept in fridge temperature ( -‬4 ‭C) for a while. Then samples were hydrated with an alcohol series and cut using Rm- ‬5 ‭microtome. ‬5 ‭to m thick sections were stained with periodic acid and Schiff's reagent (PAS) and toluidine blue O. Preparations were studied under a light microscope and photographs were taken using ISO Konica Minolta color film. As a result, the number of gum duct in the bark of root, stem and leaf was discriminated in the various species of banah seedlings. So it is possible to identify different banah genotype through this differentiation. Moreover, it was demonstrated that despite of former idea for resin production of seedlings, it is possible to have resin product at seedling stage. Key words: Pistacia atlantica subsp mutica, gum, resin, one-year old seedlings, resin ducts, nitrogen, phosphorus.‬
