Identification of Red-Fruited Pears by Fourth Derivative Spectroscopy of Intact Lamina
Intact lamina (leaf blade) of young leaves from red-fruited pears were analyzed by fourth derivative attenuance (~absorption) spectroscopy. This method was used to extend electrophoresis based identification procedures. When the two methods were used in combination before fruit development, red-fruited pears were distinguished from the non-red-fruited parent cultivars, and these from other red-fruited and non-red-fruited pear cultivars.
