to study the physiological and morphological relationships of two clover species affected by herbicides, pursuit experiment in a factorial based on randomized completely design with 3 replications at the damavand in 2012. the first factor consisted of two species of trifolium pretense l. and trifolium alexandrinum l. and the second factor consisted of three levels of herbicide pursuit (0, 0.5, ...

the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. limetta, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} were evaluated on sweet lime leaf chlorophyll content and mineral concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) in a completely randomized design of four replications. budded sweet lime on the above root...

Effect of gibberellic acid on marigold (Calendula Officinalis L.) was evaluated in a pot culture experiment. A factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. Main factor was foliar application stages (first, second and third) and sub factor included different concentrations of GA3 (0, 50, 150 and 250 mg L...

in order to study the effect of salt stress at different growth stages on physiological characteristics and enzyme superoxide dismutas (sod) activity in wheat genotypes a green house experiment was conducted at the agricultural research greenhouse, agricultural, medical and industrial research school, nuclear science and technology research institute of karaj. a split factorial design on the ba...

This study was conducted to assay the effects of methanol foliar application (0, 10, 20 and 30% v/v) and bed cover (control, white and black covers) on yield and some physiological traits of marigold as a factorial based on RCBD. The results revealed the significant interaction effects of bed cover and methanol foliar application on chlorophyll a content and plant height. The highest plant heig...
