Abstract

Salinity is one of the most extensive environmental stresses and is a limiting factor for the growth and development of crops, such as rice. Then, an experiment based upon completely randomized design with four low levels (0, 7.5, 15, 22.5) and four high of salinity (75, 150, 225 and 300 mM) with control as the first factor and nine cultivars of rice (dollars, Hasan Saraii, Mousa Tarom, Kamfiruz, Lenjan Askari, Gharib, Domsiah Mamassani, 304, Champa Yasouj) as the second factor with three replications was conducted in 2012 in the Yasouj University. Results showed that Hasan Saraii had salinity tolerance with the most germination percentage, germination rate and shoot length at high salinity levels (more than 75 mM), and Domsiah Mamassani with the minimum of that traits had not any salinity tolerance. But in the low salinity (less than 22.5 mM), Hasan Saraii, Lenjan and Mousa Tarom had the highest percentage of germination. The maximum germination rate was due to Mousa Tarom and the maximum shoot length observed in Gharib variety. So it seems, if we would only consider the germination percentage, Hasan Saraii is the best variety and if the maximum germination percentage and rate are considered, the variety that would be considered is Mousa Tarom. Therefore, high salinity we should not just rely on the germination but the germination rate should also be noted and in lower salinity due to different cultivars germination percentage, germination rate and dry weight of root should be paid much more attention.

Abstract

In order to evaluate the effect of priming on some germination and seedling growth characteristics of safflower (Carthamus tinctorius L.) under drought stress, an experiment was conducted base on completely randomized design with four replications at the Seed Technology Laboratory of Yasouj University, in 2011. Treatments were included of five priming levels (control or no prime, hydro priming, potassium nitrate 3% (KNO3), PEG and Urea -4 bar) as the first factor and three levels of drought stress (0, -4 and -8 bar) as the second factor. The results showed that the interactions of drought stress and seed priming on germination percentage and the germination rate was not significant. But the main impact of priming and drought stress on them was so significant at 1% probability. The highest germination percentage and germination rate (75.66% and 3.62 seed.day-1, respectively) were shown in urea priming and the lowest (52% and 2.31 seed.day-1 respectively) in the control treatment (no prime). Drought stress was caused a significant decrease in germination traits. In general, the results obtained in this study showed that treatment with urea and potassium nitrate compared with PEG improved germination and seedling growth of safflower.

Abstract

In recent years the use of allopathic effects on weed management seems to have attracted many professionals. In order to investigate the effect of aqueous extracts of Yarrow (Achilla wilhelmsii L.) and Habek mint (Mentha longifolia (L.) Huds) medicinal plant on germination indices of plantain, two experiments were conducted in completely randomized design with three replications in 2014 in the laboratory of seed technology of Yasouj university. Treatments consisted of 0, 25, 50, 75 and 100% concentrations of aqueous extract of Yarrow and Habek mint aerial parts. The results showed that the extract of Yarrow and Habek mint aerial parts on germination percentage, root and shoot length, root and shoot fresh and dry weight and seed vigor was significant. The maximum percentage and rate of germination have belonged to the control treatment (distilled water) and by decreasing the aqueous extract concentrations of each plant, the percentage and rate of germination increased. The minimum percentage and rate of germination have belonged to 100% concentration of aqueous extract that had no significant difference by 75% concentration. Finally, these results showed allelopathic effects of aqueous extract aerial parts of Yarrow and Habek mint, as a bio-herbicide on growth and germination of plantain.

Abstract

In order to evaluate the allelopathic effect of aqueous extract of nine weeds species on Anise (Pimpinella anisum) seed germination and seedling growth characteristics, an experiment was conducted in the Laboratory of Yasouj University in 2014. This experiment was carried out as factorial with the aqueous extracts of nine weeds species, as the first factor, in different concentrations (10, 20, 30, 40 and 50 g.l-1), as the second factor, in a completely randomized design with four replications. The results showed that interactions between different weed aqueous extracts and concentrations had a significant impact on the germination percentage and rate, root and shoot length and weight, and vigor of anise seeds at 1% probability. The most allelopathic effects on germination percentage and rate were observed in 10 g/l of the aqueous extract of Cowherb and Corn Buttercup, in 20 to 30 g/l of Corn Buttercup and Whitetop, and in 40 to 50 g.l-1 of Corn Buttercup, Whitetop, Wild lettuce and Cowherb, which completely stopped seed germination in Anise.

Highlights:
  1.  Allelopathic effects of 9 common weedy types on germination of Anise Seed were studied in Kohgiluyeh and Boyerahmad.
  2. The effect of different concentrations of aqueous extracts of weeds on germination characteristics of anise was studied.

Abstract

Micronutrients play a great role in the production of high quality seeds, especially in terms of germination. Therefore, providing seeds with sufficient amounts of these is an important consideration in seed production. The present study was conducted as two separate experiments in the Seed Laboratory of Yasouj University in 2015. In the first experiment, the sesame seeds (cv. Darab 1) obtained from a previous split plot experiment based on RCBD, consisting of three irrigation levels (after 75, 110 and 145 mm evaporation from class A pan) and four foliar applications comprising water, zinc sulfate, boric acid and mixture of zinc sulfate and boric acid, were investigated in germination experiments in the minimum temperature (i.e., 15°C). The second experiment was a factorial based on RCD with three replications. The first factor in the eight levels included seeds soaked in water, ZnSo4, H3Bo3 and ZnSo4 + H3Bo3 and seeds with high contents of Zn (159 m Kg-1), B (15.3 m Kg-1) and Zn (139.5 m Kg-1)+ B (14 m Kg-1) and dry see as the control. The second factor was accelerated aging periods at three levels (0, 2 and 4 days) at 45°c and RH = 100%. The results showed that with a delay in irrigation time, compared with water foliar application, foliar application of micronutrients (Zn, B, Zn+B), and significantly increased germination traits. The results also suggested that, compared with seeds soaked in nutrients, seeds with high Zn and B contents significantly increased germination indices and antioxidant (catalase and peroxidase) activities, especially under accelerated seed aging.

Highlights:
  1.  The role of maternal sesame plant (cv. Darab 1) foliar application by zinc and boron elements in germination, vigour and storage capability of seeds was studied.
  2. The effect of seeds soaked in solutions enriched with zinc and boron elements on germination, vigour and storage capability of seeds was examined.

Extended abstract
Introduction: Seed germination is one of the first important and complex stages in the plant life cycle and is affected by many hereditary and environmental factors. Various factors affect germination and seedling establishment. Among these factors are the characteristics of the maternal plant (nutrition, genetics), seed treatment stage at harvest time, as well as environmental factors (temperature, water potential, and ventilation and soil compaction). Also, under the influence of seed loss during storage, seed vigor, which is known as the first component of seed quality, decrease. The aim of this study was investigation of germination and biochemichal responses of the aged seed of Fenugreek to different temperature and humidity ranges.
Materials and Methods: This experiment was conducted as a factorial based on a completely randomized design with four replications in the Laboratory of Seed Science and Technology, Faculty of Agriculture, Yasouj University in 2016. The experimental treatments consisted of nine levels of temperature (5, 10, 15, 20, 25, 30, 35, 40 and 45 degrees Celsius), water potential included seven levels (zero (control), -0.2, -0.4, -0.6, -0.8, -1 and -1.2 MPa) and seed aging at two levels (no aged (control) and aged seed).
Results: In this experiment, the effect of seed aging, water potential and their interactions on each environment on germination indices (germination percentage and germination rate, length and weight vigor index) and biochemical indices (soluble sugar, proline, soluble protein and catalase enzymes) of Fenugreek seeds were significant. The results showed that in the aged seed the germination percentage and rate and seedling vigor index tended to decrease with water potential reduce in temperature lower and higher than 20 degrees Celsius, and the amount of biochemical components of the seed (soluble sugar, soluble protein, proline, and catalase enzyme) also increase.
Conclusion: In general, germination and biochemical indices of seed of Fenugreek are sensitive to water potentials, aging, and seed germination temperatures, respectively. In terms of osmotic potential decrese, the germination temperature of less than 20 ° C resulted in increased germination resistance of fenugreek seed to a more negative water potential.
 
Highlights:
  1. Study of germination and biochemical properties of fenugreek seed aged under different level of osmotic potantials and temperatures.
  2. In areas with a lower osmotic potential it is better to cultivate Fenugreek seed at temperatures below 20 °C.
