Vigour was measured using computer-aided analysis of digital images in six seed lots of Impatiens that differed in vigour but retained greater than 86% standard germination. Seed lots that differed in initial seed vigour were selected based on the commercially used Ball Vigour Index and vigour independently assessed using saturated salts accelerated aging tests. Digital images were captured fro...

Seed germination, seedling emergence and crop establishment are important aspects of canola production, and are the main components of seed/seedling vigour. A major concern of seed businesses and canola growers alike is loss of seed vigour that may go undetected before planting. Two vigour assays, based on off-gassing of ethyl alcohol from poor vigour seed, are being developed. They are a simpl...

In order to determine the impact of thermo priming on germination of soybean seeds, an experiment was conducted as a completely randomized design with three replications. The factors of studied included different time thermo priming (control, 5 and 10 minutes) through the placing seeds were exposed to oven. The results showed that the effect of thermo priming was significant on germination perc...

In plants encouraged by the proliferation of seed, seed to plant survival factor to maintain the role is very vital and important. In order to evaluate different size effect's on the quality seedling production during germination in wheat (Triticum aestivum L.), this experiment was conducted in 2011 at Laboratory Sciences, Islamic Azad University Shahr-e-Qods Branch by a completely randomized d...

background and objectives: seed vigour is the resultant of a broad range of physiological processes which have genetic background. the study of genetic variation, play an important role in enhancing the ability of breeders in selection and breeding operation. this study aimed to evaluate rice genotypes with the physiological and morphological characteristics related to seed vigour and grouping ...

to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...

seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. in order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...

Opportunities exist for replacing reduced height (Rht) genes Rht-B1b and Rht-D1b with alternative dwarfing genes, such as the gibberellin-responsive gene Rht12, for bread wheat improvement. However, a comprehensive understanding of the effects and mode of action of Rht12 is lacking. In the present study, the effects of Rht12 were characterized by analyzing its effects on seeding vigour, seedlin...

An experiment was conducted at Indian Agricultural Research Institute, New Delhi to study the effect of pre-sowing seed treatment using different combinations of magnetic field intensities and time duration, on germination and seedling attributes in North Indian variety of tomato (var. Pusa Ruby). Seeds were exposed to static magnetic fields (SMF) of strength 50, 100 and 120 mT for 5, 10, 15, 2...

BACKGROUND AND AIMS Root traits can be selected for crop improvement. Techniques such as soil excavations can be used to screen root traits in the field, but are limited to genotypes that are well-adapted to field conditions. The aim of this study was to compare a low-cost, high-throughput root phenotyping (HTP) technique in a controlled environment with field performance, using oilseed rape (O...
