In order to evaluate the effect of deficit irrigation treatment and foliar application of ascorbic acid and jasmonic acid on morphophysiological traits of safflower genotypes (Carthamus tinctorius L.), the experiment was set out in a split plot factorial in a randomized complete block design with three replications at Shahrekord University Agricultural Research Station during the two years, i.e...

During recent years, several genotypes have been selected from Isfahan land race Kouseh. The performance of safflower selected genotypes was studied in the field conditions, at Agriculture Research Station, Isfahan University of Technology during 2003. The experiment was carried out using a split plot arrangement according to a randomized complete block design with three replications. Planting ...

The objectives of this study were to analyze genotype by environment (GE) interactions on the seed yield of 19 safflower genotypes by the additive main effects and multiplicative interactions (AMMI) model and to evaluate genotype (G), environment (E) and GE interactions using statistics parameter i.e. AMMI stability value (ASV) and ecovalence (W2i). The trials were conducted at three locations:...

To evaluate seed germination and seedling growth of safflower in moisture stress, germination of 15 genotypes at four water potential levels (ψ: 0, -0.4, -0.8 and –1.2 Mpa) was tested by Polyethylene glycol (PEG6000). Maximum germination (Gmax), germination rate index (GRI), time length to reach 50% germination (T50), rootlet length (RL) and shootlet length (SL) were investigated. Effects of wa...

Although safflower is widely distributed in Iran, other diversity centers have also been reported in many Asian and European countries, especially arid regions of the world. In this research 15 domestic and 42 exotic safflower genotypes were evaluated for drought tolerance in three locations of Najafabad (Isfahan), Jiroft and Jopar (Kerman), using a lattice design at normal and drought stress c...
