The salinization of land is a major factor limiting crop production worldwide. Halophytes adapted to high levels of salinity are likely to possess useful genes for improving crop tolerance to salt stress. In addition, halophytes could provide a food source on marginal lands. However, despite halophytes being salt-tolerant plants, the seeds of several halophytic species will not germinate on sal...

smirnovia iranica (sabeti) synonym: smirnovia turkestana (bunge) is a deciduous perennial bushy species of the fabaceae (papilionaceae) family. the species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. they have an important role in natural vegetation of desert and sand dune stabilization. limited growing areas, grazing due to good pa...

as seed germination of guava (psidium guajava) is poor and time-consuming, the effects of seed extraction technique and scarification methods on the seed germination and seedling growth of guava cv. allahabad safeda, were investigated. first experiment was conducted on extraction of guava seeds using sulfuric acid (h2so4) : seed ratios including: 1:5, 2:5 and 3:5) or manual extraction (control)...

The inhibitory e!ects of six fungicides on macrospore germination and production of secondary conidia of Claviceps africana were studied. E!ects of these fungicides on germination of sorghum seed also were determined. Panicles from male-sterile sorghums with honeydew exudate were harvested from the USDA-ARS Research Farm, Isabela, Puerto Rico in the Spring of 1997. Honeydew exudate-infested pan...

deterioration of seed is one of the most important limiting or even hindering factors in its germination. an evaluation and understanding of the factors responsible for/ and enhancing seed deterioration is of paramount importance. the main aim of this study was to determine the effects of seed deterioration on its germination and as well on the activities of antioxidant enzymes in canola culitv...

This paper aims to present a review of seed technology, seed germination and vigor methods using image processing. Computer–aided image analysis techniques have been recently developed in monitoring seed growth and vigor. Their integration with the standard germination test is needed to describe the germination performance of a seed sample with high accuracy. The use of various modern image acq...

Freshly harvested seed of #1339-1-5, a selection miiade by the late C. H. MYERS, from Wisconsin Hollander, and various strains of Glory cabbage exhibit a pronounced dormancy and uneven germination, thus extending the breeding cycle from 1 to 2 years. This type of dormancy gradually disappears during several weeks of air-dry storage at room temperature, but by this time it is too late for field ...

Germination timing influences plant fitness, and its sensitivity to temperature may cause it to change as climate shifts. These changes are likely to be complex because temperatures that occur during seed maturation and temperatures that occur post-dispersal interact to define germination timing. We used the model organism Arabidopsis thaliana to determine how flowering time (which defines seed...

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...
