Propagation of hawthorns (Crataegusspp.) is difficult, and vegetative methods are not responsive in a sufficient manner. So, seed propagation prevalently used to propagate hawthorns. However, hard endocarp embryo dormancy restrict the germination To overcome these restrictions, many treatments have been tested researches. Some them were magnificent others ineffective. It has resolved that warm ...
Cannabis sativa L. is an important medicinal plant species that grow under natural conditions and has been legalized in 20 out of 81 Turkish provinces. The female inflorescence a highly branched compound raceme with indeterminate habit growth. This results different maturing seeds on the induce physiological dormancy seeds. study aimed to improve seed germination percentage using various concen...
Given the medicinal and ornamental properties of Hawthorn (Crataegus spp.), and given that there are some problems in its propagation, which is due to the hard cover of the seeds and immature embryo, working out techniques that can facilitate the process of seeds’ germination is of great import. Thus, the present study sought to identify the best method for the purpose of breaking the see...
Smyrniopsis aucheri BOISS is an herbaceous species of Apiaceae family which seed germination is difficult. Therefore, to restore the natural habitats of this plant, it is necessary to provide information about the length and the factors that affecting seed dormancy of this plant. In order to study effect of the duration of chilling and temperature on seed dormancy and seedling establishment of ...
Adequate chill is of great importance for successful production deciduous fruit trees. However, temperate trees grown under tropical and subtropical regions may face insufficient winter chill, which has a crucial role in dormancy productivity. The objective this review to discuss the challenges chilling requirements trees, especially warm regions, climate change conditions. After defining dorma...
The length of potato tuber dormancy depends on both the genotype and the environmental conditions during growth and storage. Abscisic acid (ABA) has been shown to play a critical role in tuber dormancy control but the mechanisms regulating ABA content during dormancy, as well as the sites of ABA synthesis, and catabolism are unknown. Recently, a temporal correlation between changes in ABA conte...
junglerice, c4 plant and thermo-live of poaceae family, is one of the most serious grass weed in the tropics and subtropics. to determine methods for breaking dormancy, characterizing cardinal temperatures and investigating the effect of salinity and drought on junglerice seeds germination four separate experiments were conducted in the laboratory. results showed that the junglerice seed dorman...
Abstract Seed dormancy is a mechanism of long survival that ecologically important for seed propagation and dispersal the expansion plant populations. The impermeability coat in Fabaceae family due to layer sclerotic cells. Two experiments were conducted investigate effect different treatment on germination parameters seedling growth Cercis siliquastrum Spartium junceum. Experimental treatments...
