Correlation between pigment content in generative organs and caryopse biomass in parental forms and hybrids of Triticale
1993
Kirichenko, E.B. | Martynov, O.L.
The changes of chlorophylls a and b content during the growth and development of anthers and caryopses of parental forms and hybrids of winter and spring triticale were studied, as well as dry weight of mature seeds. The elevated pigment content in generative organs of hybrids appear to be due to the alteration of nuclear-plastid interactions in them. The positive correlation between integral content of pigments in developing caryopses and dry biomass in mature grains was found. This correlation was closer in hybrids than in parent forms. The triticale hybrids had higher protein content in developing caryopses than parent forms. This phenomenon can be explained by photosynthetic activity of pericarp plastids
