The effect of combined heavy metals on the growth of wheat were studied. The result showed that the height and fresh weight of wheat seeding treated by combined pollution(Cu-Hg,Cd-Hg and Cu-Cd-Hg)are lower than the average of single pollution.
The contents of four endogenous hormones showed insignificant difference at 0.25mmol/L and a increase at 2.50mmol/L comparing with the contrast. The accumulation of IAA, GA and ZR in wheat inhibited the growth of wheat seeding and induced ABA increment.
Under the changed watering condition of progressive soil water stress-rewater, the betaine content and the betaine aldehyde dehydrogenase (BADH) activity were the highest while the tissue relative water content (RWC) of winter wheat seedling was in the range of 80 % to 70%. The betaine content and the BADH activity reduced when the seedling RWC was higher than 80% or lower than 70%. And the change of both was synchronous.
Effect of Heavy Metals on Wheat Seedlings: Activation of Antioxidant Enzymes
It was concluded that the membranotropic effect of multicomponent contaminants was due to accumulation of heavy metals capable of inducing the antioxidant protection in the next generation of wheat seedlings.
Change in Lectin Specificity of Winter Wheat Seedlings in the Course of Infection with Mycoplasms
Anionic peroxidase (pI ～ 3.5) and oxalate oxidase (pI ～ 7.0) were isolated from wheat seedlings using chitin.
Spraying wheat seedlings with these extracts, in contrast to the irrigation of soil, markedly diminished infection in plants with powdery mildew.
The data obtained demonstrate the capacity of lectins LI and LII from the soil nitrogen-fixing bacteria Bacillus polymyxa 1460 to change their proteolytic activity after interaction with surface carbohydrates of wheat seedling roots.
In contrast to BHT, they reduce production by the etiolated wheat seedling system.
It has been established that the DNA and H1 histone contents in aged coleoptile of 8-day-old etiolated wheat seedling are about 40 and 30%, respectively, lower than those in young seedlings.
Investigation of the initial stages of interaction of the bacteriumAzospirillum brasilense with wheat seedling roots: Adsorption
Role of the Polysaccharide Components of Azospirillum brasilense Capsules in Bacterial Adsorption on Wheat Seedling Roots
Available soil moisture at wheat seeding and amount and distribution of rainfall during the vegetative and the reproductive phases of crop development affected N use efficiency by wheat.
The NO3-N and available soil moisture at wheat seeding along with split rainfall for two main phases of crop development and fertilizer N accounted for 96% variation in wheat yield across years and FYM treatments.
Cold soils are also not a concern in winter wheat seeding.
Simulations were started 1 year before wheat seeding in unfertilized and fertilized wheat-fallow rotations, and were continued until wheat maturity.
Workload is spread well in the rotation unless winter wheat seeding and soybean/sunflower harvest overlap.
Winter Wheat Seedling Emergence from Deep Sowing Depths
Effects on winter wheat seedling growth by toxin-producing rhizobacteria
The allelopathic effect of alfalfa (Medicago media Pers.) and red clover (Trifolium pratense L.) root saponins on winter wheat seedling growth and the fate of these chemicals in soil environments were studied.
