Stigma Kigelia
نویسنده
چکیده
HPLC analyses of phenolics in the stigma of fruit bearing and fruitless plants of Kigelia pinnata syn. K. africana (Bignoniaceae) was made. The HPLC chromatograms showed higher peaks and higher number (9) phenolic compounds in the stigmas of fruitless plants at Agra. On the other hand, the peaks were low and there were only 8 and 7 phenolics in the stigmas of fruit bearing trees at Jammu and Dehra Dun respectively. The quantity of phenolic compounds in the fruitless plants was significantly higher as compared to that in the fruit bearing plants. Presence of higher number of phenolics and their higher quantity in the stigmas of fruitless plants inhibit pollen germination and render the plants fruitless at Agra.
