Germination of immature (Stage III) and mature (Stage V) wheat (Triticum aestivum L. var. Chinese Spring and Yamhill) embryos is prevented by the inclusion of 10⁻⁴ M abscisic acid (ABA) in culture medium. In addition, Stage III embryos develop into mature embryos in culture medium containing ABA. In the absence...
A set of genes which show developmental and tissue
specificity are expressed late in embryo maturation during
grain formation in wheat (Triticum aestivum). Two members
of this maturation gene set (MGS) are Em and triticin, a 7S
globulin. Results presented here show that during
embryogenesis, the expression of Em mRNA...
A quantitative and predictive measure of seedling vigor during the regeneration chain would be of utmost help for forest regeneration work. This was the impetus
to study the possibility of using abscisic acid (ABA) concentration of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) needles as an indicative measure of seedling vigor prior...
