Viability of stored pollen grains of Malus domestica Borkh, cultivars "Golden delicious" and "Starkrimson" is expressed as: 1) percentage of labelled generative and vegetative cells after feeding with 3H-thymidine and 3H-uridine; 2) percentage of germinated pollen grains.

Abstract
Viability of stored pollen grains of Malus domestica Borkh, cultivars "Golden delicious" and "Starkrimson" is expressed as: 1) percentage of labelled generative and vegetative cells after feeding with 3H-thymidine and 3H-uridine; 2) percentage of germinated pollen grains. The ability to incorporate nucleic acid precursors ecreases during storage; the vegetative cytoplasm response to storage is slower than the nuclear response, in respect to both 3H-thymidine and 3H-uridine incorporation. The germination ability is not influenced by the investigated storage. No relationship between the capacity of incorporating nucleic acid precursors and pollen grains germination is therefore detectable.File | Dimensione | Formato | |
