A study was conducted to check the effect of different sowing dates and row spacing on the growth, seed yield and quality of offseason pea (Pisum sativum L. cv. Climax). Significant differences were recorded among sowing dates for days to germination while nonsignificant results were found for row spacing and interaction (A × B). Maximum days to germination were recorded in D1 (20 th April) and...

INTRODUCTION An efficient and reliable method to estimate plant cell viability, especially of pollen, is important for plant breeding research and plant production processes. Pollen quality is determined by classical methods, like staining techniques or in vitro pollen germination, each having disadvantages with respect to reliability, analysis speed, and species dependency. Analysing single ce...

The ingestion of seeds by vertebrates can affect the germinability and/or germination rate of seeds. It is, however, unclear if an earlier germination as a result of ingestion affects later plant performance. For sago pondweed, Potamogeton pectinatus, the effects of seed ingestion by ducks on both germinability and germination rate have been previously reported from laboratory experiments. We p...

The Striga species are obligate root parasitic plants. Plant growth promoting rhizobacteria could enhance Striga suicidal germination. In screen-house studies we quantified the effect of bacterial inoculation with increasing maize plant density on the parasitic weed Striga hermonthica. The design used was a randomized complete block with a factorial design (4 plant density levels, 2 S. hermonth...

Current research on effect of increasing concentrations (0 (control), 100, 200, 300, 400 and 500 mM) of different salts including NaCl and Na2SO4 on germination and initial growth phase of Halostachys caspica were studied. The experimental design was completely randomized design with three replications. Characters of percentage, speed and index of germination, seed healthy index, radicle, plumu...

Variation in seed weight is common within and among plant species, but few studies have attempted to document the pattern of seed weight and germination attributes for aquatic macrophytes at a large scale. This study examined within-species variation in seed weight and germination attributes and the effects of environmental factors on seed traits of the submerged plant Potamogeton pectinatus in...

current research on effect of increasing concentrations (0 (control), 100, 200, 300, 400 and 500 mm) of different salts including nacl and na2so4 on germination and initial growth phase of halostachys caspica were studied. the experimental design was completely randomized design with three replications. characters of percentage, speed and index of germination, seed healthy index, radicle, plumu...

in order to investigate the effects of seed inoculation with plant growth promoting rhizobacteria (pgpr) on germination components and seedling growth of corn (zea mays l.), a factorial experiment based on randomized complete block design with three replications was conducted at the seed technology laboratory of mohaghegh ardabili university, iran, during 2008. studied factors were: corn cultiv...

The objective of the this study was to compare concentrations of nanosized TiO2 at 0, 5, 20, 40, 60 and 80 mg L(-1) with bulk TiO2 for phytotoxic and stimulatory effects on fennel seed germination and early growth stage. After 14 d of seed incubation, germination percentage highly improved following exposure to 60 ppm nanosized TiO2. Similar positive effects occurred in terms of shoot dry weigh...
