Influence of Seed Hydration on Seedling Performance

چکیده
costs, field problems, and customer complaints, product and processing costs, and improvements in the marketplace. Questions that must be asked in such an analysis include: 1) Are sales being gained or lost due to quality? 2) Do our customers have to be “sold” on our products or do the products speak for themselves? Accountability analysis is examined by asking: 1) Are problems routinely identified and corrected in all areas in a formal manner? 2) Are there organizational understandings? Who is held responsible for failure to supply and inferior quality’? Because of the increasing complexity of the seed business, more intense regulation, and much greater liability, the necessity for an effective QA program is obvious. Unfortunately the role of QC/ QA programs, which are designed to ensure a continuous supply of high-quality product and to prevent delivery of inferior quality to customers, is frequently misunderstood and misperceived as policing. The role of the QC/QA can be viewed as: 1) a measurer of performance 2) an identifier of problems; and 3) a facilitator of quality improvements. Supportive participation by quality organizations in producing, processing, and identifying quality seed suitable for a specified market, and enhancement of product performance can improve the performance of the other departments, and will ensure a successful future for the company in a highly competitive market.

Effect of Plant Growth Promoting Rhizobacteria (PGPR) on the Seed Germination, Seedling Growth and Photosynthetic Pigments of Astragalus caragana under Drought Stress
Drought stress is one of the most important factors limiting plant growth all around the world. Plant Growth Promoting Rhizobacteria (PGPR) can significantly reduce drought stress effects on plants growth. This study was aimed to investigate the influence of PGPR (inoculation by Azospirillum lipoferum, Azotobacter chroococcum, Pseudomonas aeruginosa, and Bacillus cereus) on seed germination, se...
متن کاملThe dead seed coat functions as a long-term storage for active hydrolytic enzymes
Seed development culminates in programmed cell death (PCD) and hardening of organs enclosing the embryo (e.g., pericarp, seed coat) providing essentially a physical shield for protection during storage in the soil. We examined the proposal that dead organs enclosing embryos are unique entities that store and release upon hydration active proteins that might increase seed persistence in soil, ge...
متن کاملEffects of storage duration and temperature of hydro-primed wheat seeds on seed and seedling quality
Quality of seed as a propagating organ and the most valuable input to produce crops is highly important in agriculture. Thus, the objective of this study was to compare the effects of storage temperature (15, 20 and 25 °C) and storage duration (0, 2, 4, 6 and 8 days) of hydro-primed wheat seeds of Koohdasht dry land cultivar on germination and seedling characteristics. The seeds were hydro-prim...
متن کاملEvaluation of Profitability of Seed Priming for Improvement Seed Germination Performance of Two Rangeland Plants (Festuca ovina and Bromus tomentellus) under Drought Conditions
The possible effects of seed priming on mitigating the effects of drought stress on germination and early seedling growth of two rangeland plants were evaluated in a laboratory research during 2015-16 growing season. The research was conducted as a 2×3×3 factorial experiment based on completely randomized design with three replications. The first factor was plant type (Festuca ovina and Bromus ...

Tall fescue and meadow fescue are naturally infected with fungal endophytes, Neotyphodiumcoenophialum and Neotyphodium uncinatum, respectively. Seed traits are an important measureof the effects of the endophytic fungi which has been less addressed. In this study we usedendophyte-infected (EI) and endophyte-free (EF) clones of tall and meadow fescue genotypes inthe field to investigate the effe...
