The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...

Ectomycorrhizal inoculation of Douglas-fir nursery stock with commercially produced inoculum

Creator:: Hung, Ling-ling L.
Abstract:: Nine species of ectomycorrhizal fungi were grown in liquid media over a pH range of 2-7. Species fell into five major groups: (1) growth significantly best only at the optimal pH, (2) growth increased with increase of pH, (3) significantly best growth spans three pH units, (4) spans four pH...

Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

Creator:: Ding, Pinghai
Abstract:: Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...

Taxomony and mycorrhizal ecology of the desert truffles in the genus Terfezia

Creator:: Alsheikh, Abdulmagid M.
Abstract:: Mycorrhizal fungi in arid and semiarid rangelands have received little study in southwest Asia and north Africa, although they are important in food production and rangeland productivity. The desert truffles of the genera Terfezia and Tirmania form fruiting-bodies and mycorrhizae with rangeland plants. This thesis treats the taxonomy and the...

Nitrogen, defoliation and new growth in almond (Prunus dulcis (Mill) D.A. Webb) nursery plants

Creator:: Bi, Guihong
Abstract:: The relationships between nitrogen (N), defoliation, and plant growth in nursery plants were studied using almond {Prunus dulcis (Mill) D. A. Webb) trees. In several experiments the effects of N source and availability on tree growth, N uptake, N remobilization, and nonstructural carbohydrates (TNC) were investigated to determine the most...

Alternative greenhouse tomato production system

Creator:: Albahouh, Muhammed S.
Abstract:: The closed insulated pallet system (CIPS) was evaluated for growth, yield, and fruit quality of tomato genotypes with determinate growth habit. Plants were irrigated with several levels of sodium chloride (NaCl) salinized water. Tomato growth and yield were significantly greater in CIPS than in conventional surface-irrigated containers, regardless of irrigation...

Factors affecting the incidence and severity of Phytophthora syringae cankers in pear (Pyrus communis) trees

Creator:: Laywisadkul, Srisangwan
Abstract:: Container grown pear trees were used to determine the effects of the following factors on the susceptibility to Phytophthora syringae: 1) tree nitrogen (N) status and foliar sprays of urea and copper-EDTA (CuEDTA); 2) dormancy and environmental conditions; 3) wound and wound age; and 4) chemical and biological control measures....

Postemergence herbicides and take-all disease in winter wheat : alterations in the incidence and severity of disease and crop growth

Creator:: Geddens, Ray M.
Abstract:: Eight postemergence herbicides were evaluated to determine their influence on the incidence and severity of take-all disease caused by the fungus Gaeumannomyces graminis var. tritici in winter wheat. Mecoprop ((+)-2-(4-chloro-2-methylphenoxy)propanoic acid), difenzoquat (1,2- dimethyl- 3,5- diphenyl -1H- pyrazolium), dinoseb amine (amine salt of 2-(1-methylpropy1)-4,6-dinitrophenol), and diclofopmethyl (methyl ester of (+)-2-[4-(2,4-dichlorophenoxy)...
