In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia Iberica) under different salinity levels, two factorial experiment in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the...

As seed dormancy is released within a seed population, both the rate and percentage of germination increase progressively with increasing dose of a dormancy-breaking treatment or condition. Population-based models can account for this behaviour on the basis of shifting response thresholds as dormancy is alleviated. In particular, hydrothermal time analysis of germination sensitivity to water po...

ABSTRACT: Seed priming was used in wheat seeds to increase germination characteristics and tolerance on stress exposure. Wheat seeds were treated with salicylic acid and gibberellin. After 8 days our results showed that, seed priming treatments significantly (p≤ 0.01) affected germination percentage, normality seedling percentage, germination index and seedling length. Seed priming with salicyl...

In three field trials fungicides used for stem rust (Puccinia graminis) control were evaluated to assess the effect on levels of blind seed disease, seed germination and endophyte (Neotyphodium lolii) transmission. Blind seed disease infection was reduced from 24% to 5% in one of the three trials undertaken and germination was increased by between 17 and 23% in two trials. There was a negative ...

We studied seed germination and seedling growth of the Mexican sunflower Tithonia diversifolia in Nigeria. This involved the usage of some dormancy-releasing methods and the effect of some concentrations of three herbicide formulations on the young seedlings. Initial germination tests on fresh and stored seeds revealed a low percentage germination of less than 30%. The seeds of the weed exhibit...

The dormancy status of S. faberi seed at abscission was assessed with reference to tiller and panicle development. Seed from a single genetic line were grown under field, greenhouse and controlled environment growth chamber conditions. At abscission, a small fraction (<10%) of S. faberi seed germinated under favorable conditions. Seed were dissected and germination of caryopses and embryos also...
