abstract silicon (si) is considered one of the beneficial elements for plant, however recent studies show that si plays an important role in plant resistance to environmental stresses , like salinity. an experiment was conducted to study the effect of si and nacl salinity on the growth, yield and fruit quality of strawberry (fragaria × ananassa duch) cv “selva” was grown hydroponically in the c...
There exist four major leaf shape alleles in tetraploid cotton: normal, sub-okra/Sea-Island, okra, and super-okra. This allelic series has long served as a model genetic locus both in cotton and the broader leaf development research community. Over the years, numerous studies have attributed various production advantages to specific leaf shapes. The objective of this study was to provide a comp...
Plant litter decomposition is an essential ecosystem function that contributes to carbon and nutrient cycling in streams. Aquatic shredders, mainly macroinvertebrates, can affect this process in various ways; they consume leaf litter, breaking it down into fragments and creating suitable habitats or resources for other organisms through the production of fine particulate organic matter (FPOM). ...
Light quality critically affects plant development and growth. Development of light-emitting diodes (LEDs) enables the use of narrow band red and/or blue wavelengths as supplementary lighting in ornamental production. Yet, long periods under these wavelengths will affect leaf morphology and physiology. Leaf anatomy, stomatal traits, and stomatal conductance, leaf hydraulic conductance (Kleaf), ...
Changes in land use may lead to increased soil nutrient levels in many ecosystems (e.g. due to intensification of agricultural fertilizer use). Plant species differ widely in their response to differences in soil nutrients, and for savannas it is uncertain how this nutrient enrichment will affect plant community dynamics. We set up a large controlled short-term experiment in a semi-arid savanna...
in order to determine the effects of zinc foliar application on the vegetative characteristics, yield and fruit quality in strawberry (fragaria × ananassa duch) cv kordestan under salinity stress conditions, an experiment was carried out hydroponically in glasshouse as a controlled environment during 2009 through 2010. three levels of nacl (0, 15, 30 mm) and three levels of zn (0, 1.5, 3 g/l) w...
Senescence is a genetically controlled process whose regulation depends on many factors. Leaf senescence begins with the catabolism of chlorophyll and macromolecules such as proteins and membrane lipids, a process that is accompanied by the alteration of organelles and, ultimately, the breakdown of nuclear components. In annual plants, reproduction is the main event that triggers leaf senescenc...
Chrysanthemums constitute approximately 30 species of perennial flowering plants, belonging to the family Asteraceae, native to Asia and Northeastern Europe. Chrysanthemum is a natural cosmetic additive extracted from Chinese herb by modern biochemical technology. It has the properties of anti-bacterial, anti-viral, reducing (detoxification) and anti-inflammation. It possesses antioxidant chara...
Laboratory studies were conducted with leaf powder of three plants to show the preservative effect for maintaining the quality of lentil seeds in storage. After processing and drying, seeds were preserved with different botanicals and stored them in earthen pots for eight months. Botanicals, such as whole leaf powder of neem (Azadirachta indica), dholkalmi (Ipmoea sepiara), and bishkatali (Poly...
The aim of this study was to prove whether Ginkgo biloba food supplements on the European market comply with pharmaceutical quality, and whether their composition satisfies the European Pharmacopoeia criteria. Medicinal products containing a standardised Ginkgo leaf extract are used for the improvement of cognitive impairment and quality of life in mild dementia. Further, Ginkgonis folium is us...
