EFFECTS OF SOME GROWTH SUBSTANCES ON POLLEN GERMINATION AND TUBE GROWTH IN DIFFERENT STONE FRUITS |
| Authors: | C. Vitagliano, R. Viti |
| Abstract:
Siapton 10L, a polypeptide-amino-acid mixture obtained by protein hydrolysis, stimulated in vitro pollen germination of almond, apricot and peach, whereas GA3 was without effect and paclobutrazol was inhibitory. Siapton at 500 and 1000 ppm also accelerated pollen tube growth in the style and increased initial fruit set of apricot and peach, though final yield of peach was reduced because of fruit drop. | |
