An elevated concentration of water soluble carbohydrate (WSC) in grasses may increase the availability of readily degradable energy, increase milk production and improve the efficiency of nitrogen utilisation. Two ryegrasses with elevated WSC, a tetraploid Italian (IRG) and a diploid perennial selected for higher WSC (HSG), were compared against a standard diploid perennial (STG) during spring ...

The objective of this research was to analyse whether ameliorating drought stress through exogenously applied spermine (Spm) was related to carbohydrate metabolism, dehydrins accumulation and the transcription of genes encoding dehydrins in two white clovers (drought-susceptible cv. 'Ladino' and drought-resistant cv. 'Haifa') under controlled drying conditions for 10 days. The results show that...

water and soil salinity in some regions of isfahan, east azerbaijan, and west azerbaijan provinces and also other parts of the iran are the main hindrance for crop planting. seeds of the tolerant crops to salinity such as cotton and sugar beet may have optimal germination and give acceptable performance if they become far from salt accumulation areas. to evaluate the effects of different planti...

for determination of water stress effects in different growth stages of sugar beet and optimum water usage on quantity and quality of sugar beet, this study was performed using randomized complete blocks design in factorial experiment with 12 treatments and 4 replications from 1999 to 2001 in agricultural research center of hamadan. the first factor was non-irrigation in 3 stages of growth (s1-...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...

effects of the last irrigation time on quantitative and qualitative traits were studied for two sugar beet cultivars with intermediate and long growth periods. this research was conducted in the field of agricultural and natural resources research center of khorasan at mashhadin 1381. six treatments of withholding irrigation were applied on the cultivars using a spilit plot design within a rand...

in order to assess the heritability of short vegetation period (early maturity) of sugar beet hybrids, an experiment was carried out in randomized complete block (rcb) design with 4 replications in abdolrasoul motahari agricaltural research station of sugar beet seed institute, karaj, iran in 2009. in this research, the heredity of the traits in testcrosses derived from crosses of 18 half sib f...

abstract             this study was conducted to investigate the effects of different levels of yeast and molasses on chemical composition and nutritional value of artiplex lentiformis silage. the levels of yeast include: zero (control), 2.5 and 5 g/kg dry matter and levels of molasses include: zero (control), 10 and 15 percent that were added to atriplex and then ensiled. the experiment arrang...

for optimum utilization of saline soil and water resources, various methods have been proposed. application of best management practices and selection of salt tolerant cultivars are two important issues. selection and breeding for salt tolerant cultivars require potential genetic materials, screening and evaluation of them in laboratory and field experiments. starting in 2000, 80 sugar beet gen...
