Imbibition of wheat seeds: Application of image analysis**
*Corresponding author e-mail: [email protected] **This work was supported by the Internal Grant Agency of the Czech University of Life Sciences Prague, Project No. 20163001, (2016). A b s t r a c t . Image analysis is widely used for monitoring seeds during germination, and it is often the final phase of germination that is subjected to the greatest attention. However, the initial phase of germina...
متن کاملPhysiological Predetermination: Imbibition, Respiration, and Growth of Lima Bean Seeds.
Temperatures 15 degrees C or lower during the first hour of imbibition immediately inhibited respiration in lima beans, with proportional inhibition of subsequent growth of seedlings. Correlations between initial respiration rates and growth rates of seedlings were found in diferent lots of seeds.
متن کاملProtein Synthesis in Imbibed Seeds. Ii. Polysome Formation during Imbibition.
Ribosomes prepared from dry wheat embryos or peanut cotyledons show little or no capacity to incorporate 14C-amino acids into protein. In contrast, preparations from imbibed embryos or cotyledons are active (1). In the presence of polyuridylic acid, the ribosome system of dry seed is as active as that from imbibed seed in catalyzing 14C-phenylalanine incorporation (1). These results suggested t...
متن کاملActivation of gibberellin biosynthesis and response pathways by low temperature during imbibition of Arabidopsis thaliana seeds.
Exposure of imbibed seeds to low temperature (typically 4 degrees C) is widely used to break seed dormancy and to improve the frequency of germination. However, the mechanism by which temperature accelerates germination is largely unknown. Using DNA microarray and gas chromatography-mass spectrometry analyses, we found that a subset of gibberellin (GA) biosynthesis genes were upregulated in res...
متن کاملExpression of circaseptan and circannual rhythmicity in the imbibition of dry stored bean seeds.
Water uptake of seeds of Phaseolus vulgaris L. cv Limburg was monitored in a controlled atmosphere every day at solar noon for a period of 2 years. The imbibition rate, determined as the mean of five replicas, was related to the lunar cycle, maximal water uptake occurring between the new phases of the cycle. The monthly mean value of imbibition rate, calculated from the daily measurements, disp...
