Appropriate management in all steps from planting to harvest together with using suitable colons, could be beneficial to increase wood requirement of the country and alleviate human interventions in natural forests. Rapid growth, suitable physical, chemical and mechanical characteristics of poplars wood is the principals of their different usage. In poplars habitats, weeds are the most common problem from the view point of wood production. The weeds are important as influencing factors to decrease the amount of plant yields; therefore, the first step of wed eradication is the accurate identifying different species and genus of weeds and floristic investigation of the area. In this research which was carried out in Ghareh-chi river side, first of all weeds samples were taken and preparation process including (drying, pressing and sticking on paper) were done in Markazi province herbarium. Than scientific references books and flora were used to identify the weeds species, based on this research 88 species, 72 geniuses and 23 families were introduced. Investigation of life form (Raunkiaer method) indicated Therophytes with 39 species (%44.8) are most abundant and 33 species was annual and 47 species was perennial.

There are about 8 species and sub species of maples in northern forest of Iran. Maple tar spot is one of the most important diseases in most parts of the world .It is caused by two species of Ascomycets (Rhytisma acerinum and R. punctatum). In this study, effect of these fungi on native maples of northern forest along with the bio-ecological aspects of the fungi has been studied in East of Mazandaran. The results showed that Acer velotinum and A. capadocicum have been infected more than the others, while Acer monspessulanus subsp. turcomanicum and A. hyrcanum were not infected. A. campester and A.ibericum were infected but not as much as Acer velotinum and A. capadocicum. The first symptoms of disease appeared about 4-6 weeks after discharging the ascospores, from June to July. In late summer tar spots cover most of the leave areas and causes premature defoliation. As the fungi overwinter on leaves, destroying fallen leaves is the best management practice of the disease in parks and plantation areas.

The common pistachio psylla (Agonoscena pistaciae Burckhardt & Lauterer) is one of the most important pests of the cultivated pistachio trees and wild pistachio growing areas in Iran. Life table parameters and functional response of Coccinellid beetle, Oenopia conglobata contaminata Menetries as the dominant species and the most important Coccinellid predator of the common pistachio psylla in wild pistachio growing areas was determined under controlled conditions. The rate of natural increase (rm) and finite rate of increase (λ) were 0.16 and 1.18, respectively. The gross reproduction rate (GRR) and net reproduction rate (R0) was 308.74 and 202.81, respectively. The mean generation time (T) was 32.5 days and the population doubling time (DT) was 4.24 days. In order to determine functional response type of this predator different densities of fourth psyllid instar nymphs were examined. It was found the functional response to be type ІІ. The searching efficiency (a) and handling time (Th) were 0.0469 and 0.0152, respectively.

Mangrove forests are vegetative formations in tropical and subtropical latitudes at intertidal extension. These vegetative communities have rich biomass as food source in their established regions. Mangrove trees in their biotic extension produce large amount of litter which support food elements circulation in mangrove ecosystems and neighbor habitats. Govater bay is located at the South-East of Iran and is neighbor to Pakistan. Three estuaries with grey mangrove are joined to this small bay. Two estuaries including Govater and Bahu are in Iran and Jiva estuary is in Pakistanian side. Govater bay is a part of international wetland and Gando protected area and has unique ecological values. Mangrove stands of this wetland consist of a single species called Harra (Avicennia marina Frossk. (Vierh.)). In this survey, samples were collected using four transects in Govater and Bahu estuaries. Twigs with three repeats and sediment in two depths were collected in each transect. Some parameters such as N, P, and K, Organic carbon, humidity percent of stem, leaf and sediment were measured and statistic differences and correlations were studied. Based on the obtained results, the sediment of these forests are very rich in terms of P and K amount. There was significant difference between P and N in two different depths. In all stem and leaf parameters significant differences were observed between amount of these factors (expect carbon). Correlation between sediment parameters with twig and leaf was very low and only between K of surface samples with K of stem significant correlation was occured. Investigation on nutrient amount show important role of mangrove trees in food chain and habitat fertility.

In the cource of the research during 2001-2005, 35 soil samples were collected from root zone as well as infected roots, of medicinal plants in farms and natural plantations of medicinal plants in Qazvin province (“Dineh” Agricultural Complex, natural plantations and Alamout Medicinal Plant Research Station). Samples were transferred to laboratory. Washing, nemathode extraction, killing, fixation and transfer to pure glycerin were carried out based on the modified protocol developed by De Grisse (1969). Perineal pattern of Meloidogyne females was prepared through IMP method. Infected roots were studied in two ways of dyed (using fuxin lactophenol acid) and non-dyed.Important morphological and morphometric characteristics were investigated after supplying permanent preparation of extracted nemathodes. Results showed 9 species of nematode belong to 9 geneus of 5 families were identified on rizosphere of Thymus vulgaris,Salvia officinalis,Melissa officinalis, Lavandula officinalis and Mentha piperita.

Four years studies (1999-2002) on more than 100 cultivated medicinal plant species and their soil specimens to identify and examine population dynamics of medicinal plants' parasitic nematodes in Isfahan province revealed the presence of several plant parasitic nematodes in the rhizosphere. The nematode genus present in Dastgerd station belong to the follwing genus: Helicotylenchus, Meloidogyne, Goeocenamus, Longidorus, Ditylenchus, Tylenchus, Criconemella, Xiphinema, Psilenchus, Pratylenchus on the basisof population density respectively. Whereas in Kashan station, Tylenchus, Xiphinema, Helicotylenchus, Meloidogyne, Geocenamus and in Najafabad station, Meloidogyne, Helicotylenchus, Geocenamus, Ditylenchus, Xiphinema, Tylenchus, Criconemella, Pratylenchus, Aphelenchus, Psilenchus and in Mobarakeh station Criconemella, Longidorus, Xiphinema, Meloidogyne, Tylenchus, Helicotylenchus, Geocenamus had the most densities in mentioned stations respectively. The follwing species were identified as parasitic nematodes in the studied areas: X. index, X. pachtiacum, X. vuittenezi; L. africanus , H. pseudorobustus, H. digonicus, H. vulgaris; M. javanica, M. incognita; G. brevidens, G. microdorus, G. rugosus; Criconemella antipolitana, C. xenoplax; Psilenchus hilarulus; Ditylenchus dipsaci, D. destructor, D. acutus; Pratylenchus neglectus, P. penetrans, P. thornei and P. minyus .

The genus Rosa from Rosaceae family has 18 species in Iran of which 12 are self-growing shrubs and the species R. persica, R. orientalis, R. pulverulenta, R. iberica, R. hemisphaeria, R. boissieri, R. elymatica grow in many countries as well. Many forms & cultivars from the genus grow in temperate and cold areas of Iran. In this survey, an important disease that damage these plants in Lorestan province was found and powdery milews on two species of this genus namely Rosa canina L. & R. elymatica Boiss & Hausken were identified. The symptoms include white, dusty appearance on upper surface of leaves, petals, fruits and stem of the infected plants. Mycelium of the causal agent is white in colour, and there is clistothecium into the hyphae. There is few appendage beneath the cleistothecium. Cleistothecium is 100-157 µm, asci have ellipsoid shape and are 71-105×90-195 µm. Ascospore is ellipsoid to egg shape and 20-21×22-39 µm in size. Conidia are ellipsoid egg to barrel shape and have 9-14×19-30 µm size. By comparing the characters of the disease agent to special key for this fungus (Braun 1978 , Braun & Takamatsu 2000), the fungus was idendified as Podosphaera panosa (Lév.) Braun & takamatsu with synonyme of Sphaerotheca parasa (Wallr. Fr.) Lév. The fungus has been reported so far on plant species of Rosasp., Hultemia persica (Michx. ex Juss.) Staef (syn :Rosa persica MichX. ex Juss.) & R. multiflora Dum. but this is the first report of occurance of this fungus on the two plant species, Rosa canina and R. elymantica from Iran.
