Publikováno v: Plant Cell, Tissue and Organ Culture. 6:149-157
Rice, Oryza sativa, plants regenerated from anther culture with and without in vitro selection pressure were evaluated for chalky seed. Progeny evaluated included 21 spontaneously doubled haploids selfed 4 times, progeny from plants regenerated from

Effects of Variables in Weather and Their Interactions on Metaphase Cells in Root Tips of Grasses
Autor: Helen D. Hill, H. L. Carnahan
Publikováno v: Botanical Gazette. 116:82-86
1. For the practical purpose of obtaining root tips likely to show metaphase cells, it may be concluded that the flourishing condition of the plant is of paramount importance. 2. The production of metaphase cells by the clone of meadow fescue showed
