aging coefficient (ac) or aged-child ratio or age composition; takes into account the numbers and areas at both ends of the age distribution simultaneously. ac is the total number of individuals aged 65 years and more, divided by the total number of individuals aged 14 years, multiplied by 100. herein, age composition in iranian popu1ations, according to different provinces, place of residence ...
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...
Abstract Key message Environmental stress resulting from rapid climate changes leads to the initiation of seed aging process in mitochondria and peroxisomes. Seed storage methods limiting germinability loss are fundamental for forest future. is a natural process. It decreases germination rate, i.e. essential plant’s life cycle. Aging involves progressive accumulation oxidative damage over time....
Superoxide generated during the early imbibition is an excellent marker for evaluating seed vigor. In this paper, a new principle biosensor for non-invasive detection of seed vigor based on quantitative measurement of superoxide via selective probe 2-methyl-6-(p-methoxyphenyl)-3,7-dihydroimidazo [1,2alpha] pyrazin-3-one (MCLA)-mediated chemiluminescence (CL) was developed. The biosensor, which ...
In order to study of quantitative and qualitative yield, chlorophyll content and some growth indices of wheart (Triticum aestivum L.) in response to seed inoculation with plant growth promoting rhizobacteria (PGPR) at different levels of soil salinity, a factorial experiment based on randomized complete block design with three replications was conducted at Research Greenhouse of Faculty of Agri...
BACKGROUND Skin aging is a natural process that may be aggravated by environmental factors. Topical products are the conventional means to combat aging; however, the use of oral supplements is on the rise to assist in the management of aged skin. OBJECTIVE The purpose of this study was to assess the effects and safety of an oral supplement containing (per tablet) marine protein (105 mg), vita...
