FT-IR Characterization of Pollen Biochemistry,Viability,and Germination Capacity in Saintpaulia H. Wendl. Genotypes

Ft-ir characterization of pollen biochemistry was analyzed to detect possible connection with the viability (by staining with potassium iodide,25%) and the germination capacity (on solid nutrient medium),in 15 saintpaulia genotypes. vibrational spectroscopy indicates that the pollen of s. ionantha genotype red velvet is rich in proteinş lipidş triglycerideş and esters and has a viability of 88.4% and a low germination capacity (27.16%). for s. ionantha jolly red and lucky ladybug genotypeş pollen showed high viability (88.81-91.49%) and low germination capacity (23.02-9.17%),even though the pollen is rich in carbohydrates. s. ionantha aloha orchid genotype has the highest percentage of viability (94.32%) and germination capacity (45.73%) and a rich content of carbohydrates and polygalacturonic acids. in s. rupicola and s. ionantha genotypeş the rich content of polygalacturonic acidş lipidş and carbohydrates favourably influenced the germination capacity. spectroscopic result indicateş through different absorbance band intensity,a possible link between biochemical composition,viability,and germination capacity of saintpaulia pollen. to determine exactly the relation between biochemistry and biological processeş it is necessary to initiate quantitative researches. © 2015 erzsebet buta et al.
