Industrial hemp (Cannabis sativa L.) is experiencing a resurgence in North America as an agricultural commodity. Germplasm improvement for locally adapted and stable cannabinoid production industry priority. This study used seed priming pericarp removal to recover seedlings low-germinating lots that could prove important plant breeding germplasm conservation. Both improved early germination, bu...

ABSTRACT- This experiment was carried out during the growing seasons of 2010 and 2011 at the Agricultural Research Farm of Bu-Ali Sina University, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. Experiments consisted of two sets of treatment...

Interspecific hybrids between cultivars of eggplant (Solanum melongena L.) and its wild relative S. torvum, which has disease resistance and desirable traits for crop improvement, were obtained by cross-hybridization and embryo rescue. Twenty-one hybrid progenies were obtained and examined based on morphological traits, RAPD and ISSR markers. Five of them were confirmed to be true interspecific...

Sacred lotus (Nelumbo nucifera) has been cultivated as a crop in Asia for thousands of years. An ∼1300-yr-old lotus fruit, recovered from an originally cultivated but now dry lakebed in northeastern China, is the oldest germinated and directly (14)C-dated fruit known. In 1996, we traveled to the dry lake at Xipaozi Village, China, the source of the old viable fruits. We identified all of the la...

Although Azospirillum spp. are considered to be important plant growth promoting bacteria, their possible effects on germination and vigor of aged lettuce seeds has not been previously evaluated. In fact, there is a paucity of published data about inoculation effects on seed germination. The aim of this work was to evaluate seed quality of oneyear aged lettuce (Lactuca sativa L. cv. Crimor INTA...

Allelochemical compounds are present in tissues of different plants` parts and also in other organisms, being released into the environment and thus affecting plants development. There is evidence that secondary metabolites produced by weeds may exhibit several allelopathic effects. This study aimed to evaluate allelopathic activity based on the interaction of aqueous extracts preparations and ...

The conditions that cause the development of symptoms of frenching in tobacco {Nicotiana tabacum L.) plants are unknown. Low nitrogen, ^ low acidity, and excessive moisture ^ have at times been held to be contributing factors. Nevertheless soil from fields of severely frenched plants was often incapable of producing this morphological abnormality in the greenhouse. Abnormal plants transplanted ...

The aim of the research was to evaluate influence year and seed lots on most important indicators cabbage quality. Quality testing nine different Potomac F1 performed during three years (2019, 2020 2021). Analyses variance showed a significant effect (p<0.01) (Y), while lot (L) their interaction (Y × L) (p<0.05) all observed parameters quality (germination energy, total germination, abnor...

Gravity and light are major factors shaping plant growth. Light perceived by phytochromes leads to seedling deetiolation, which includes the deviation from vertical hypocotyl growth and promotes hypocotyl phototropism. These light responses enhance survival of young seedlings during their emergence from the soil. The PHYTOCHROME KINASE SUBSTRATE (PKS) family is composed of four members in Arabi...
