Garden orache (Atriplex hortensis L.), a halophytic forb in the family Chenopodiaceae, is well adapted to dry saline habitats. Here, we presented the results of the effect of salinity and seed weight on seed germination and radicle emergence of A. hortensis. Highest germination percentages were obtained under non-saline conditions and increases in salinity inhibited seed germination with less t...

Flax (Linum usitatissimum L.), an oilseed crop, is widely adapted and grown in many regions of the world. Oil from regular flaxseed is used as an industrial drying oil because of the high level of linolenic acid (>50 %). However, the oils from new mutant genotypes of flax with a very low linolenic acid concentration (<2 %) are edible. Yellow seed colour can be used as a visual marker to disting...

in order to evaluate the response of emergence rate of oil seed rape seedlings to temperature, a pot experiment was conducted to assess the relationship between emergence rate of three rape seed cultivars (apetalous flower, rgs003 and syn3) by using a non-linear regression against temperature variation. six models (tooth shape, segmented, beta, curve, quadratic and cubic) were used and the supe...

Seed priming is a physiological seed enhancement method. Hydroor osmotic priming can advance germination under adequate moisture conditions. During direct seeding on well-drained paddy and upland fields, rice seeds occasionally encounter low soil moisture conditions. Under these conditions, rice seeds need to undergo rapid germination and secure emergence through improved water absorption capac...

The genus AnthemisL. (Asteraceae) as medicinal plants are used both for pharmaceutical purposes and in folk medicine. In order to study of seed priming effects on seedling growth of two species of Anthemis spp., an factorial experiment based on randomized complete design with three replications was conducted under greenhouse conditions in Research Institute of Forests...

In order to study the effect of seaweed extract and nano-ZnO on germination characteristics of tomato seed, a factorial experiment was conducted based on a randomized complete block design. Preliminary germination and seedling growth tests were performed to determine the best concentration of seaweed extract and nano-ZnO. Experimental treatments included three levels of drought stress (0, 2- an...

Studying seed dormancy and its consequent effect can provide important information for vegetation restoration and management. The present study investigated seed dormancy, seedling emergence and seed survival in the soil seed bank of Stipa bungeana, a grass species used in restoration of degraded land on the Loess Plateau in northwest China. Dormancy of fresh seeds was determined by incubation ...

in this study 21 coriander populations the accumulated from different regions of iran was conducted¬ augmented design at shahid chamran university of ahvaz. some of morphological characteristics (time of emergence, plant height, fresh and dry weight, seed weight)and anti¬oxidant (carotenoids, vitamin c, catalas and proxidase) of these populations were evaluated. the analysis of variance showed ...

Chamomile (Anthemis haussknechtii Boiss. & Reut. and Anthemis pseudocotula Boiss.) are annual, medicinal and aromatic plant belong to Asteraceae family. This two species have special important in pharmaceutical and cosmetic industries. Current study was carried out to investigation of different pre-treatments for enhancement of seed emergence potential, rate of emergence and v...

Priming is one of the seed enhancement methods that might be resulted in increased seed performance (germination and emergence), seedling growth and plant yield under stress conditions, such as salinity, temperature and drought stress. In order to evaluate the effect of growth hormones on morphology characteristics and essential oil of basil under drought stress condition, a experiment was cond...
