BACKGROUND AND AIMS Sanqi ginseng (Panax notoginseng) growth is often hampered by replant failure. In this study, we aimed to examine the role of autotoxicity in Sanqi replant failures and assess the role of ginsenosides in autotoxicity. METHODS The autotoxicities were measured using seedling emergence bioassays and root cell vigor staining. The ginsenosides in the roots, soils, and root exud...
a paper-pot transplanter was designed, developed and evaluated in the field by transplanting sugar beet seedlings grown in paper pots. a ground-driven counter wheel equipped with an infra-red sensor measures the traveled distance and sends the corresponding signals to a micro-controller. a step motor controlled by the micro-controller turns the driving shaft of the paper-pot metering mechanism ...
In order to study of drought stress and normal irrigation effect on seed germination and seedling vigor of 10 oilseed rape spring genotypes, RGS003, Sarigol, Option 500, RGS006, 19_H, ORS3150-3006, ORS3150-3008, RG4403, RG405/03 and RGAS0324, an experiment was conducted as factorial, based on a completely randomized design with four replications, in the seed analysis laboratory of Seed and Plan...
Extended abstract Introduction: Heavy metals pollution is one of the most important environmental problems. This type of metals with accumulation in the food chain has a lot of human and animal hazards. Among heavy metals, lead is considered to be the most dangerous of heavy metals in the environment, which is contaminated with the environment through the lead-acid battery industry, paint addi...
Cucumber seeds were taken to assess the effect of temporal variation on the seed quality. Seeds were stored in three types of containers, such as metal (tin), polythene bag, and cloth bag. The containers were stored at room temperature and ambient relative humidity around three months. Seed quality factors viz., moisture content, germination percentage, vigor index, percentage of abnormal seedl...
Abstract: The use of computational tools has become notable in seed quality control to assist confirming lots higher potential. Thus, the aim this study was a approach investigate analysis morphological parameters that characterize primary root emergence evaluation tomato vigor. For purpose, five were analyzed for germination and vigor (seedling seedling images). A parallel made using computer-...
A quantitative trait loci (QTL) analysis of seedling vigor traits was conducted under dry-seeded conditions using recombinant inbred lines derived from a cross of the California varieties M-203 and M-206. Height at early seedling (HES) and height at late seedling (HLS) stage, growth rate (GR), and fresh weight (FW) were evaluated under controlled environmental conditions. HES, HLS, and GR were ...
background & aim: because of seed germination ability of medicinal plants seed is low and, generally exposed to problem. priming is one of the techniques that help seeds to be germinated faster and uniformly. experimental: a laboratory experiment was carried out on germination and growth improvement in heracleum persicum desf. by seed osmo-primming in seed technology laboratory ...
Abstract: Seed quality is extremely important for agribusiness, as it can affect the stand establishment, well competitive ability of plant, affecting its yield potential. The aim present work was to evaluate initial development and production performance maize crop a function vigor seed lots. experiment consisted 10 treatments, involving two factors: stands (ideal number plants ideal seeds cor...
