In this study, the effects of seaweed extract (Ascophyllum nodosum) on seed germination stimulation and growth indices in chickpea were studied. A factorial experiment was performed on the basis of a completely randomized design with 3 replications. Treatments consisted of seaweed extract at four levels (0, 1.5, 2.5 and 3.5%) and drought stress at four levels (0, -0.3, -0.6 and -0.9 MP). Drough...
The need to identifying seeds with low vigor and poor emergence led to introduce of various seed vigor tests. The purpose of this experiment was to assess the ability of controlled deterioration test for evaluation of seed vigor and prediction of oilseed rape seed lots emergence in the field. Samples of 19 seed lots were obtained from nineteen farmers of Razavi and Northern Khorasan Provinces...
Efficient seed germination and rapid and uniform seedling emergence are important in commercial agriculture. Therefore, the use of strategies to improve germination and seedling establishment is necessary for increasing productivity. Hydropriming has been suggested as a simple pre-germination strategy to improve seed performance. In this study, the effects of different durations of hydropriming...
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...
A study was conducted for assessing quality of 15 hybrid rice seed samples and management of seed borne fungal pathogens by three selected chemicals namely Bavistin (0.3%), Thiovit (0.3%) and Provax (0.3%) along with two botanicals such as: Garlic extract (Allium sativum) (1:1) and Allamanda leaf extract (Allamanda cathartica) (1:1) and a bio-control agent BAU-Biofungicide @ 3% (Trichoderma bas...
The Ormosia hosiei is a secondary protected wild plant in China, and its seed has hardness rate of 86%. To explore the characteristics hard difference vigor between seeds non-hard O. hosiei, water absorption characteristics, germination coat structure, permeability, enzyme activity, main biochemical substances were determined. results showed that dense obstacle to absorbing seeds; reason compos...
Abstract: The use of computational resources to assess the physiological potential seeds has attracted attention researchers and professionals in seed sector. aim this study was evaluate vigor cowpea using Vigor-S software (Automated Seed Vigor Analysis System), comparison information provided by traditional tests that are recommended for species. Seven lots cultivar BRS Guariba were used. They...
Galactinol synthase (GolS) catalyzes the first and rate limiting step of Raffinose Family Oligosaccharide (RFO) biosynthetic pathway, which is a highly specialized metabolic event in plants. Increased accumulation of galactinol and RFOs in seeds have been reported in few plant species, however their precise role in seed vigor and longevity remain elusive. In present study, we have shown that ga...
