SUNFLOWER VARIETY PEREDOVIK

Influence of drought stress on growth, protein expression and osmolyte accumulation in sunflower Helianthus annuus L. c.v. Peredovik

Drought stress causes considerable yield losses in agriculture and receives high attention in current sunflower breeding programs. For this study, an in vitro system based on MS media (Murashige and Skoog, 1962) supplemented with polyethylene glycol 6000 (Korell, 1997) was established to examine sunflower (Helianthus annuus L.) seedlings under artificial drought stress conditions. The objective...

A model-based approach to assist variety evaluation in sunflower crop

Assessing the performance and the characteristics (e.g. yield, quality, disease resistance, abiotic stress tolerance) of new varieties is a key component of crop performance improvement. However, the variety testing process is presently exclusively based on experimental field approaches which inherently reduces the number and the diversity of experienced combinations of varieties x environmenta...

Sunflower Resistance to the Red Sunflower Seed Weevil (Coleoptera: Curculionidae)

a determination of physical and aerodynamic properties of sunflower seed, (azargol variety as a case study)

a knowledge of physical properties of sunflower seed is essential for the design and development of such processing equipment as handling, separating, dehulling and storing. in this research, physical properties of sunflower seed, (azargol variety as a case of study, was investigated at various moisture contents (3-14% d.b) and in three categories of big, average and small sizes samples. the re...

effect of plant density on yield, agronomic traits in new variety sunflower

in order to study the effect of plant density on yield and agronomic traits on new sunflower varieties in esfahan condition, an experiment was conducted in 2009 cropping season at agricultural research institute kabotar abads. the experimental design was factorial in a randomized complete block design with four replications. the experimental treatments were at 4 levels of plant density (6,8,10 ...
