Juvenile growth and bud set phenology were analyzed to study the biological basis of heterosis (hybrid vigor) in interspecific hybrids of Populus tremuloides Michx. (T) and P. tremula L. (Ta). Growth, measured as seedling volume index, was significantly higher for each of the two reciprocal interspecific crosses, T x Ta and Ta x T, than for the T x T intraspecific cross. Broad-sense heritabilit...

The study was conducted over a period of six months from January to June 2004 to explore the effects of different seed treatments on germination and seedling growth attributes of a popular medicinal plant, Horitoki (Terminalia chebula Retz) in the nursery of Chittagong University, Bangladesh. Seeds were subjected to six pre-sowing treatments e.g. control (T ), depulped (T ), depulped and soaked...

Impatiens seeds treated with the ethylene biosynthetic precursor 1-aminocyclopropane-1-carboxylic acid (ACC) had reduced times to radicle protrusion and seedling emergence. Sixty hours after imbibition, 68% more seeds showed radicle protrusion on media containing 0.1 or 1.0 mM ACC compared to seeds germinated on water alone. Subsequently, ACC was effectively “loaded” into impatiens seeds using ...

ABSTRACT- Seed germination and early seedling growth are critical stages for plants establishment and production, particularly under salinity conditions. Exogenous application of silicon (Si) can enhance germination as well as seedling growth. In this experiment, the effect of priming with Si (0, 0.75, 1.5 and 2.25 mM sodium silicate) on seed germination and seedling growth under NaCl (0, 100 a...

Abstract: The use of computational resources to assess the physiological potential seeds has attracted attention researchers and professionals in seed sector. aim this study was evaluate vigor cowpea using Vigor-S software (Automated Seed Vigor Analysis System), comparison information provided by traditional tests that are recommended for species. Seven lots cultivar BRS Guariba were used. They...

Safflower germination and seedling growth stages are extremely sensitive to salinity. The study aimed identify safflower genotypes' germination, responses, biochemical changes in tolerant susceptible genotypes response salt stress. Total of 28 were subjected (NaCl) treatments (0, 180, 240 mM), percentage, mean time, root lengths, vigor index the determined. genotype, treatments, interaction eff...

The growth and yield of plants are strongly influenced by the early ability plants. Similar germination good seed vigor will greatly support plant increase production. Increasing seeds can be done through biopriming. application biopriming using rhizobacteria is developing environmentally friendly agricultural technology. This study aimed to determine effect inoculation from north coast Pemalan...
