We show that for any two values α, β ∈ (0, 1) for which α+β > 1 then there exists a value N so that for all n ≥ N , and any binary phylogenetic tree T on n leaves there exists a set of at most n characters that capture T , and for which each character has at most n states. Here ‘capture’ means that T is the only phylogenetic tree that is compatible with the characters. Our short proof of this c...

In order to investigate the appropriate combination of chemical and bio-fertilizers and their effectiveness on corn seed yield while defoliating the upper leaves of the ear, a randomized complete block design experiment with four replications. Fertilizer treatments were applied at four levels including 100% urea, 75% urea + 100% Nitroxin, 50% urea + 100% Nitroxin, 25% urea + 100% Nitroxin. In h...

tolerance of two apple rootstocks (gami and m26) was evaluated at different concentrations of sodium chloride in vitro conditions. micro plants grown under ms medium culture were transferred to knoudson–c culture medium devoid of na and cl ions. concentrations of nacl in the knoudson-c culture medium were 0, 20, 40, 60, 80 and 100 mm/l. six weeks after culturing, data were collected. the result...

The aim of the present study is to evaluate the effect of ethanolic extract of leaves of Leptadenia reticulata leaves (LELR) against Dalton’s Ascitic Lymphoma (DAL) in Swiss Albino mice. DAL cells were injected intraperitoneally (106 cells/mouse) to the mice. Two days after cells injection the animals were treated with 200 mg/kg of LELR for 8 days. Five-fluorouracil (20 mg/kg) was used ...

water deficit stress permanent or temporary limits the growth and distribution of natural vegetation and performance of plants more than other environmental factors. in order to investigate the effect of drought stress and mycorrhizal-arbuscular fungi inoculation on the growth and yield of savory (satureja hortensis l.) a factorial experiment based on completely randomized design were conducted...
