The purpose of this study was to determine whether the rates of tomato seed germination under different stress and nonstress conditions were under common genetic controls by examining quantitative trait loci (QTL) affecting such traits. Seeds of BC(1) progeny of a cross between a slow-germinating tomato breeding line and a rapid-germinating tomato wild accession were evaluated for germination u...
The response of tomato genotype Cal-ji against five salinity levels (distilled water as control, 25, 50, 75 and 100 mM) were studied at germination and early seedling stages. An experiment with conducted by using a completely randomized design (CRD) with three replications. Shoot and root length, shoot and root fresh weight, seed vigor, mean germination time, germination percentage an...
For many species and seed sources used in restoration activities, specific seed germination requirements are often unknown. Because seed dormancy and germination traits can be constrained by phylogenetic history, related species are often assumed to have similar traits. However, significant variation in these traits is also present within species as a result of adaptation to local climatic cond...
Extended Abstract Introduction: Guar (Cyamopsis tetragonoloba L.) is an annual, dicotyledonous plant of the legume family, also known as cluster beans. This plant can tolerate salinity and drought stress well. Optimal planting date and plant density are factors affecting the quality and quantity of crops. The distribution of plants in the field influences the absorption and productivity of env...
DOR: 98.1000/2383-1251.1397.5.101.9.1.1578.1610 Extended abstract Introduction: Stevia is a perennial short day plant, belonging to the Asteraceae family. It is also called sugar leaf. Poor germination of this plant serves as a barrier for its planation on a large scale, which contributes to its scarcity and expensivenss as a medicinal herb. In many plants, seed germination is sensitive...
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 Labora...

Rapid and uniform seed germination is a crucial prerequisite for crop establishment and high yield levels in crop production. A disclosure of genetic factors contributing to adequate seed vigor would help to further increase yield potential and stability. Here we carried out a genome-wide association study in order to define genomic regions influencing seed germination and early seedling growth...
In order to investigate the effect of priming techniques on germination parameters of ajowan (Carum copticum L.) seed, an experiment was conducted in completely randomized design with four replications. The experiment treatments included a control (no priming), three hydropriming levels with distilled water (24, 36, and 48 h), three osmopriming levels with PEG (solutions with osmotic potential ...
Introduction: salinity is known as the most important inhibitor of seed germination of most plants and limits the establishment of plants in arid and semi-arid regions such as Iran. The first effects of salinity on plant growth are associated with reduced seed germination and lack of uniformity in plant emergence. Currently, identification and utilization of tolerant cultivars are one of the mo...
