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...

Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...

The transition from dormancy to germination in seeds is a key physiological process during the lifecycle of plants. Abscisic acid (ABA) is the sole plant hormone known to maintain seed dormancy; it acts through a gene expression network involving the transcription factor ABSCISIC ACID INSENSITIVE 3 (ABI3). However, whether other phytohormone pathways function in the maintenance of seed dormancy...

BACKGROUND AND AIMS The water-impermeable seeds of Ipomoea lacunosa undergo sensitivity cycling to dormancy breaking treatment, and slits are formed around bulges adjacent to the micropyle during dormancy break, i.e. the water gap opens. The primary aim of this research was to identify the mechanism of slit formation in seeds of this species. METHODS Sensitive seeds were incubated at various ...

to study the effect of some varying treatments including such environmental factors as temperature, moisture, and light as well as plant growth regulators on breaking dormancy of datura stramonium l. seeds, several experiments were conducted. seeds of datura stramonium l. possess full dormancy immediately following harvest. storing the seeds for 3 months (15 dec. 2005 to 15 march 2006) at room ...

Seed dormancy can prevent germination under unfavourable conditions that reduce the chances of seedling survival. Freshly harvested seeds often have strong primary dormancy that depends on the temperature experienced by the maternal plant and which is gradually released through afterripening. However, seeds can be induced into secondary dormancy if they experience conditions or cues of future u...

Seed dormancy has played a significant role in adaptation and evolution of seed plants. While its biological significance is clear, molecular mechanisms underlying seed dormancy induction, maintenance and alleviation still remain elusive. Intensive efforts have been made to investigate gibberellin and abscisic acid metabolism in seeds, which greatly contributed to the current understanding of s...

Coffee seeds take a long time to germinate, as the tough seed coat can cause dormancy. This is because water absorption and gas exchange are disturbed mechanical barrier. Breaking of dormancy maximize germination needs be done before sowing seeds. The aim this study was obtain an appropriate effective soaking agent for breaking Kerinci arabica coffee research conducted using Randomized Block De...
