in order to evaluate the effect of priming on germination of black cumin under different levels of salinity, a factorial experiment on base of completely randomized design was conducted with three replications. the main factors consisted of five levels of priming (osmopraiming with kno3 (1 and 3%), salicylic acid (sa) (0.2 and 0.5 mm) and a hydropriming)) and four salinity levels (zero, 75, 125...
To evaluate the effect of priming on seed germination of Cucurbita pepo in drought stress conditions, a factorial experiment was conducted as completely randomized design with three replications. Treatments included drought stress at five levels of osmotic potential (zero, 0.3, 0.6, 0.9 and 1.2 MP), priming at levels of GA3 (250 ppm to 24 hours), KNO3 (0.2% for 24 hours) Hydro prime (H2O) (to 2...
Drought stress influences seed germination and seedling growth of many plants. Seed coating is technique of covering seeds with adhesive agents to improve seed performance and plant establishment and could be used to alleviate the negative effects of osmotic stress. In order to solve the problem of low germination and poor vigor of sweet corn under osmotic stress conditions (0, -0.3, -0.6 and -...
Extended abstract Introduction: Today, various technologies have been developed to improve seed quality with the aim of increasing the percentage, speed and uniformity of germination and better seedling establishment under different environmental conditions. One of these technologies is seed pre-treatment or seed priming. In this regard, some studies confirmed that pre-treatment of seeds with ...
To investigate the role of seed size on maize germination characteristics, an experiment was conducted in 2014 in the Laboratory of Registration and Certification of Seeds and Plants, Khuzestan Branch. Treatments included three levels of seed size (control (mixed), large and small) and hybrids at three levels (KSC704, Karun and Mobin). The results of these experiments showed that the hybrid had...
this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...
Accelerated aging test to estimate the percentage of emergence are designed to lay the seeds for life, as well as an indicator to determine the power of the seed used. In this study, the effects of aging zero (control), 2, 4 and 6 days on germination index of rapeseed genotypes including Okapi, R15, BAL11, L109, BAL2 Were detected in a factorial experiment based on completely randomized design ...
to determine the effect of seed size of sugar beet cultivars on germination and seedling vigor, a study was conducted as a 4×6 factorial experiment based on completely randomized design with 4 replications at seed and plant certification and registration institute, karaj in 2013. the treatments were toucan, dorotea, rasta, sharif, pars, and torbat cultivars and four seed width sizes including 2...
This research was conducted to assessment effect of different concentrations of sodium hypochlorite along several times on quantitative parameters of wheat seeds affected by Aspergillus flavus fungus via factorial experiment according randomized complete block design with four replications. The treatments consisted four concentrations of sodium hypochlorite or NaClO (C1= 2%, C2= 4%, C3= 6%, and...
Soil moisture is one of the most important determinants of plant’s seed germination, emergence and finally yield formation in arid and semi-arid zone (e.g. IRAN). In such a situation, the selection of a cultivar resistant to drought is the most important task. In this regard, a research at three levels (Farm, Greenhouse, Laboratorial) was conducted to study 10 genotypes with three improved back...
