Poszukiwanie samorzutnych mutantów woskowych wśród ziaren pyłku u kilku gatunków i linii 24-chromosomowych ziemniaków [The searching for the spontaneous waxy mutation in pollen grains of some diploid forms of wild potatoes]

Abstract

Only in one of 12 investigated species i.e. in Solanum chacoense (gibberulosum) which became pollen staining red when treated with I+KI was been found. However in three forms: Solanum verrucosum, 133 Solanum chacoense (Schickii) and 127 Solanum chacoense (gibberulosum) the dimorphism of starch grains within the anther wall has been observed. It can be assumed that in these forms starch with a prevailing amount of amylopectin will be formed.
