Vine-leaved kitaibelia (Kitaibela vitifolia Willd.), also known as balkanmalva or chalice flower, is a critically endangered plant species with high risk of extinction in the wild. A reason given for this is, among others, low germination rate primarily caused by dormancy. The present study evaluated seed and seedling growth parameters vine-leaved response to eight different pre-sowing treatmen...

Teak is a wood-producing plant that in great demand by the community. However, teak seeds are challenging to germinate due dormancy, so special treatment needed before planting. This research aimed determine effect of hydrochloric acid and soaking time on breaking dormancy seed improve its viability. The first factor was concentration with four levels, i.e., 0 M, 0.5 1 1.5 M. second submerging ...

to study seed dormancy and the after-ripening period in barley genotypes (57 dutch genotypes and two iranian cultivars (gorgan and valfair)), an experiment of randomized complete block design (two replications) was conducted at the research farm of collage of agriculture and natural resources, university of tehran in 2004-2005. in the growing stage of zgs92, panicle was collected. the percentag...

Dormanit seeds of Hazel (Cworylus avellatta L.) re(luire a period of after-ripeniing at low temliperlat'ire before they beconme capable of subsequent germiination. (Gibberellic acid (GA;) c-n fully replace this requirement (2, 6). The identification of gibberellin-likz substar.s in extracts of chilled ( noni-dormant) seeds led Frankland and Wareiing (7) to suggest that gibberellin synthesis nma...

In the present study, dormancy and germination requirements were investigated in seeds of Citrullus colocynthis (L.). Seeds were subjected to 10 pretreatments in the present study.  These pretreatments included hot water (100° C) followed by the seeds placed between double layered filter paper moistened with 5 ml of distilled water and kept at 28 - 30 °C, sulphuric acid (98% v/v), for 30 min fo...

The medicinal plant, coastal glehnia (Glehnia littoralis F. Schmidt ex Miq.), belongs to the Apiaceae, which is known exhibit morpho-physiological seed dormancy (MPD). In this study, we aimed determine type of along with conditions for breaking dormancy, and how increase its germination rate mass production. Initially, seeds had undeveloped embryos, gradually developed following cold (5 °C) str...

Dormancy and germination requirements were investigated in seeds of Ferula gummosa Boiss (Apiaceae) and Teucrium polium L. (Labiatae). Seeds of both species were subjected to different treatments including various levels of GA3, HNO3, H2SO4, chilling and soaking with water at different temperatures. Germination of both species increased at higher concentrations of GA3. In the case of F. gummosa...

The present study investigated the expressional regulation of PpDAM5 and PpDAM6, two of the six peach (Prunus persica) dormancy-associated MADS-box genes, in relation to lateral bud endodormancy. PpDAM5 and PpDAM6 were originally identified as homologues of Arabidopsis SHORT VEGETATIVE PHASE/AGAMOUS-LIKE 24 identified in the EVERGROWING locus of peach. Furthermore, PpDAM5 and PpDAM6 have recent...
