in order to study the role of photosynthetic tissues on grain filling and remobilization of stem reserves under terminal drought, a pot experiment as semi-field was conducted as two-factor factorial in complete randomized design with three replicates at research farm of agriculture college of vali – e – asr university of rafsanjan during january to june 2012 . first factor was source strength r...

Phytophthora capsici Leon. is the main pathogen that limits production of peppers. In this study, effects 1 and 10 mM proline (Pro), prior to exposure resistant (CM-334) susceptible (SD-8) pepper seedlings P. , on some physiological parameters were investigated. A lower Pro concentration (1 mM) was found be more effective than in increasing stress tolerance CM-334 cultivar. Namely, cultivar, hi...

Brown stem rot (BSR) caused by Cadophora gregata f. sp. adzukicola (syn. Phialophora gregata) is a serious soilborne disease of adzuki bean (Vigna angularis) in Japan. Cultivation of resistant cultivars is the most effective disease control method, therefore the selection of resistant lines is a priority for breeders. BSR-resistant adzuki bean lines have been screened in pathogen-infected field...

The degree of resistance by a cotton plant to Meloidogyne incognita is affected by soil temperature, particularly in moderately resistant cultivars, The total number of nematodes in the resistant and moderately resistant rools at 35 C was equal to, or greater than, the number in susceptible roots at 20, 25, or 30 C. A shift in numbers to developing and egg-bearing forms of nematodes in the susc...

in order to study the role of phytophthora species associated with greenhouse cucumber root and crown rot, diseased sampled were collected in southern kohgiluyeh and boyerahmad province. pieces of infected root and crown of cucumber were washed with tap water blotted dry and plated on cma supplemented with delvocid (10 ppm pimarcin), ampicillin (250 ppm), rifampicin (10 ppm) and pcnb (150 ppm)....

Inoculation of plant pathogenic bacteria in field plots has been improved by the use of organosilicone surfactants. Factors, such as cultivars, number of applications, crop stage, plant density, concentration of bacteria, and irrigation application method (overhead spray versus drop hoses), that may affect field screening of cotton cultivars for resistance to bacterial blight caused by Xanthomo...

This study investigated the interactive effects of different rates of deficit irrigation and timings of N application on wheat and barley yields since there was no report on this important subject. Field experiments in strip-plot designs using sprinkler line sources were conducted for two years at a semi-arid Mediterranean site. The experiments consisted of 4 and 7 irrigation levels with 3 and ...

'flying dragon' is one of the citrus rootstocks that are considered to be a promised dwarfing rootstock in the world. this experiment was conducted in the astara research station for study of qualitative and quantitative characteristics of 4 mandarin cultivars (unshiu, clementine, page, and yunesi) budded on 'flying dragon'. this experiment was carried out with four cultivars in randomized comp...
