DELLA-Mediated Cotyledon Expansion Breaks Coat-Imposed Seed Dormancy
Seed dormancy is a key adaptive trait in plants responsible for the soil seed bank. The long established hormone-balance theory describes the antagonistic roles of the dormancy promoting plant hormone abscisic acid (ABA), and the germination promoting hormone gibberellin (GA) in dormancy control. Light, temperature, and other dormancy-breaking signals function to modulate the synthesis and perc...
متن کاملSoybean Seed Coat and Cotyledon Crack Detection by Image Processing
A computer vision system was used to evaluate seed coat and cotyledon cracks in soybeans. White light in the front-lighting mode with a black background for the soybeans was the best condition for acquiring video images of soybeans suitable for subsequent processing. Image processing algorithms were developed using the software supplied with the vision system computer. Crack detection was most ...

متن کاملThe qSD12 locus controls offspring tissue-imposed seed dormancy in rice.
Seed component structures were grouped into maternal and offspring (embryo and endosperm) tissues to characterize a dormancy quantitative trait locus (QTL) for tissue-specific function using a marker-assisted genetic approach. The approach was devised to test if genotypic/allelic frequencies of a marker tightly linked to the QTL deviate from Mendelian expectations in germinated and nongerminate...
