Depending on the initial pressure, temperature, amount of H2, and the rate of heat gain from the ambient, the endothermic para-to-ortho conversion can extend the loss-free dormancy time by up to 85%.
Atwell et al. (2010) measured six phenotypes directly related to germination and dormancy: time to 50% germination after two different storage conditions and percent of (nondormant) seeds germinated after 1 wk under four conditions (in the dark at 4° and under 16-hr days at 10°, 16°, and 22°).
It is also involved in many adaptive responses of plants11, such as root development and architecture, seed dormancy, flowering time, circadian system, leaf development, stomatal movements, and auxin transportation (long-term processes)12,13,14,15,16,17,18,19,20,21.
The physics of cancer dormancy, the time between initial cancer treatment and re-emergence after a protracted period, is a puzzle.
Natural variation was found for many traits in Arabidopsis, including seed germination and dormancy, flowering time, plant architecture and morphology, growth, primary and secondary metabolism, responses to biotic and abiotic stresses, etc. [3].
Soybean has undergone radical phenotypic changes in the seed size, colour, shattering, seed dormancy, flowering time, and plant architecture during the process of domestication.
Payne et al. [ 22] dealt with BC dormancy, the time between removal of the primary tumor and subsequent relapse of patients who have been clinically disease-free [ 23].
The dissemination of cancer cells may occur at an early stage of malignancy, but tumor cell dormancy, a time lag between tissue infiltration and tumor formation, may result in metastatic latency [ 63, 64].
The following equations describe logistic functions which were used to model the probabilities of primary and secondary dormancy over time x: (4) P (D p ) = 1 1 + e R p (x + A p ), (5) P (D s ) = 1 − [ 1 1 + e R s (x + A s ) ], where R p and R s are the rates of primary dormancy loss and secondary dormancy induction; A p and A s are offset parameters.
