nowadays, tobacco is considered as one of the important world industrial plants. in the present study, for a creation of somaclonal variation, calli were produced on ms medium supplemented by 2 mg/l of naphthalene acetic acid (naa) and then regenerated on ms medium supplemented with 1 mg/l benzyl amino purine (bap) and 0.1 mg/l of naa. to determine correlations among traits and to fit multiple ...

The effect of cement dust on the growth parameters of brinjal (Solanum melongena) was studied. The cement dust (2 g/plant) exhibited both inhibitory and promotory effects on different growth parameters of the S. melongena. The decrease in the number of leaves (37.19 and 62.28%), leaf area (57.93 and 57.26%), root length (48.21 and 56.75%), shoot length (27.27 and 38.98%), plant circumference (3...

seventeen iranian shallot genotypes from ashtian, arak, boroujerd, dashtearjan, doshmanziari, divandareh, khomein, khansar, sepidan, siakhdarengoon, sahne, kangavar, koohrang, koohmaresorkhi, nahavand, harsin and yasouj areas were evaluated for their morphological traits. corms were collected from the mentioned regions and planted based on a complete block design. quantitative and qualitative t...

abstract for evaluation and identification some of the chamomile species in two genera anthemis and matricaria, morphological and phonological characteristics were used. the experiment was conducted in a randomized completely blocks design (rcbd) with three replicates, sixteen quantitative and qualitative traits were evaluated such as plant height, anthodium diameter, receptacle diameter, ligul...

Twenty available genotypes of maize were screened for resistance to Chilo partellus in the field. The genotype Sahiwal 2002 was found to be most susceptible while DK-6525 was most resistant. Maximum infestation was observed at the end of April while the minimum in the last week of March. Significant variations were observed in all the plant characters viz., number of nodes per plant, plant heig...

breeding programs strategies depends on genetical mechanism of selection traits. in the present research, generation mean analysis with joint scaling test was performed to determine the gene action. f1, f2 and f3 generations, derived from roushan and kavir cross along with their parents were sown in a partial lattice design with two replications under stress condition at the research field of s...
