Seed weight is a very important and complex trait in rapeseed (Brassica napus L.). The seed weight of rapeseed shows great variation in its natural germplasm resources; however, the morphological, cytological and genetic causes of this variation have remained unclear. In the present study, nine highly pure inbred rapeseed lines with large seed weight variation and different genetic backgrounds ...

milkthistle (silybum marianum l.) is a rangeland medicinal plant growing wild in different locations in iran. in the present research work, the effect of n, p and k in their different proportions of n0p0k0, n100p100k50, n150p150k100 and n200p200k150 kgha-1 as compared with control (no fertilizer application) on the plant's growth was put to test. suc variables as plant height, no. of capit...

THE FIRST step in producing a satisfactory crop of tobacco is to use good seed that is true to type. The grower often can save his own seed to advantage, if he wants to. Before topping is done, he should go over the tobacco field carefully to pick out desirable seed plants. When he has decided on the ideal type of plant, he should select the plants that conform to this type for producing seed. ...

physical properties of four common iranian varieties of canola seeds (hyola, okapi, orient and slm) were evaluated as a function of their moisture contents. the average seed length and thousand seed mass varied linearly from 1.925 to 2.262 mm and from 3.06 to 4.84 g, respectively. the average diameter, geometric mean diameter, and sphericity varied non-linearly from 1.475 to 1.911 mm, 1.625 to ...

Salicylic acid (SA) is a phenolic compound and its foliar application shows regulatory effects on plants. In this research, Ajowan (Carum copticum) plants were treated with 0, 0.5, and 1 mM SA and proline, total phenol, chlorophylls, carotenoids, soluble sugar, N, P, and K contents were studied. Results showed that application of SA affected both quantitative and qualitative traits of ...

the effect of drought stress on yield and components of three varieties of autumnal rapeseed in the south ‎eastern region of isfahan, utilizing four irrigation regimes (i.e. no irrigation from flowering stage on, no ‎irrigation from the podding stage on, no irrigation from grain filling stage on, and a normal irrigation regime ‎after 80 mm evaporation from class a evaporation tube) were studied...
