In a test of early genetic evaluation of the growth potential of 14 families of open-pollinated Douglas-fir (Pseudotsuga rnenziesii [Mirb.] Franco), measures of growth and phenology of seedlings grown in a coldframe were correlated with height of saplings in evaluation plantations at 9, 12, and 15 years. Fifteen-year height was most strongly correlated with measures of seedling budset (r = -0.5...

salinity and drought stress are among the common environmental factors which adversely affect germination and growth of plants. this experiment was conducted to evaluate the effects of salinity and drought stress on turnip seed germination and early growth in seed lab of college of agriculture, university of tehran, during 2010. the experimental design was a complete randomized block with three...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

Maternal control of seed size in the common bean provides an opportunity to study genotype-independent seed weight effects on early seedling growth and development. We set out to test the hypothesis that the early heterotrophic growth of bean seedlings is determined by both the relative amount of cotyledon storage reserves and the genotype of the seedling, provided the hybrid genotype could be ...

The effect of seed size on germination and early growth of maize plant, was examined within three weeks to determine the best seed size require for planting. The larger size seed produced significant growth compared to medium size and small size. The seedling height, seedling width, and seedling biomass increased in larger size seed. The significant growth observed in larger size seed showed th...

soil and water salinity are the main agricultural problems in arid and semi arid areas in the world and iran. in order to investigate salinity tolerance of kochia, two experiments were conducted in a completely randomized design with four replications, seven levels of salinity (0, 10, 20, 30, 40, 50 and 60 ds m-1) and two growth stages (planting and early seedling) with gradually salinity appli...

soil salinity threat for agricultural ecosystems in many parts of iran, and negatively affects crop production. in order to examine salinity tolerance of kochia a series of experiments were conducted in crd with four replications, seven levels of salinity (0, 10, 20, 30, 40, 50 and 60 ds.m-1), two growth stages (planting and early seedling) and interval irrigation. result showed that decrease o...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

an investigation was initiated to examine the effects of nanoscale titanium dioxide particles on plant growth and development. in view of the widespread cultivation of canola in iran and in other parts of the globe and in view of the potential influence of titanium on its growth, this plant was chosen as the model system. canola seeds were separately treated with different concentrations of nan...
