drought preconditioning (dp) is a method of irrigation with low frequency and longer duration, to extend the root system and suppress drought damage in plants. in the present study, the effect of dp for 30 days on increasing tolerance to drought stress in two turfgrass species, creeping bentgrass (agrostis stolonifera cv.palustris) and tall fescue (festuca arundinacea cv. greystone) was investi...

Different methods have been proposed for in situ root-length density (RLD) measurement. One widely employed is the time-consuming sampling of soil cores or monoliths (MO). The profile wall (PW) method a less precise, but faster and laborious alternative. However, depth-differentiated functions to convert PW RLD estimates MO measurements not yet reported. In this study, we perform regression ana...

A study was conducted in growth chambers to examine main factor and interaction effects of Tylenchorhynchus nudus and Magnaporthe poae on creeping bentgrass and annual bluegrass at 24, 28, and 30 C. A 2 x 2 factorial arrangement of treatments was employed with presence and absence of T. nudus and M. poae as factors with each temperature run separately for 14 or 18 days. Tylenchorhynchus nudus d...

in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...

Cadmium (Cd) pollution of agricultural soils is a growing global concern. Plant growth restriction the main visible symptom Cd toxicity, and this metal may be particularly harmful to preformed, seminal root during pre-emergence stage. In present study, we focused on phytotoxicity in growth, nutrient composition, redox status, hormone homeostasis stage maize (Zea mays L) plants, distinguishing b...

A major problem of arid and semi-arid regions is environmental stresses like salinity and drought. To study the effect of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The experimental treatments included different salinity levels of NaCl (0, 50, 100, 150 mM) and five drought levels by PEG (0, 10%, 15%, 20% and 25%) with three rep...
