common burnet (poterium sanguisorba) is a perennial herb from rose family (rosaceae) which is used to construct pastures. the studied plant can resist against freezing, cool and drought. the present study was conducted to study the seed germination parameters of common burnet in different thermal treatments as completely randomized design in 4 replications in 2013. treatments involved the effec...

to study the effects of chilling on dormancy breaking and the increased germination characteristics of nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. factor a was the chilling treatment in three levels (control, one-month and two-month ...

Separately, it is well-documented that phytochromes (phys), gibberellin (GA) and abscisic acid (ABA) strongly control the seed germination in tomato. However, we hipothesized that phys interact with GA or ABA during this response. Thus, we make an analysis of seed germination of ABA deficient (sit), GA constitutive response (pro), phytochrome deficient (au) mutants as well as, specially, au sit...

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...

damping-off is an important disease of safflower in iran, that caused by pythium ultimum. because of its importance, fungi isolates were sampled from infected plants grown in research farm of the college of agriculture, gorgan university of agricultural sciences and natural resources, in 2006. also it has been proved that the disease caused by pythium ultimum. evaluation of seventeen safflower ...

Rapid germination is important for both direct seeded rice in the field and production of germinated brown healthy food. This study aims to evaluate genotypic differences speed identify characteristics that determine speed. Seven experiments were conducted (i) impact dehulling on water absorption germination, (ii) variety consistency across crops grown three years, (iii) effect grain size. Germ...

This research has been done to examine the effect of bio-priming on germination parameters related to seeds of canola cultivar (Hayola 401) under high salinity as factorial in seed laboratory of Shahed University based on a Completely Randomized Design (CRD) in three replications. Experimental factors included bio-primin...
