several species of phytophthora cause crown and root rot diseases of herbaceous and woody plants. crown and root rot of pistachio trees cause significant damages in infected orchards. the effect of foliar application with elite (fosetyl-al) in 2 and 2.5 g/l was evaluated in greenhouse experiments. the frequency of mortality, fresh and dry weight of roots and shoots, height, intensity of crown r...

Nine bacterial isolates from the rhizosphere and(or) tubers of potato (Solanum tuberosum cv. Kennebec) at a field site on Prince Edward Island were assessed as food sources for a bacteria-feeding nematode species tentatively identified as Diplogaster lheritieri. This species was the most common rhabditid nematode recovered from soil around potato roots at the same site. In laboratory feeding tr...

Risk analysis is an important technique to estimate impacts on the environment for adopting effective measures to avoid risks. This field study was conducted to investigate the risk of brick kiln (BK) smoke on the shoots of Acacia arabica. Different phenotypic parameters including morphology and growth of shoots and epidermal imprints of the leaves were studied in the vicinity of a brick kiln s...

due to the importance of production and propagation of virus-free potato plants, some of the factors involved in the propagation of potato (plantlet production and virus-free in vitro microtuberization) has been studied. in most reports, adding a mixture of amino acids play an important role in plant tissue culture and development of the explants in many cases increase. this experiment was cond...

This study examined the lodging resistance of mulberry tree (Morus bombycis Koidz. cv Kenmochi) shoots treated or not treated with succinic acid 2,2-dimethylhydrazide (SADH). The lodging safety factor, an indicator of lodging resistance, was defined as the ratio of critical lodging load to the leaf fresh weight observed, provided that the distribution of the critical lodging load along the stem...

thyme (thymus vulgaris l.) is an aromatic and medicinal plant which is very important for the herbal industry. in this research, in vitro selection for nacl tolerance was investigated in this plant. hypocotyl and shoot explants (apical meristem and cotyledonary leaves) of sterilized seedlings were cultured in ms medium supplemented with different combinations of 2, 4-dichlorophenoxyacetic acid ...
