Abstract:
This research aimed to study the effects of silver nitrate (AgNO3) solution and AgNO3 with NAA on characteristic changes of gac female flowers. The solution of 500 mg/L AgNO3 was sprayed on 6 months female plants at 17.30 p.m. After 1 week, the changes were recorded when the first flower emerged. The results showed that filament and anther were induced in female flowers of the three sample groups; Thailand, Lao People’s Democratic Republic, and Socialist Republic of Vietnam. However, pollen grain was not found inside the induced anthers. Applications of 500 mg/L AgNO3 with 1,000 mg/L or 2,000 mg/L NAA on two sample female; Thailand, and the hybrid between Lao People’s Democratic Republic × Socialist Republic of Vietnam could produce the sterile stamens similar to the result of using AgNO3 solution only. The treated ovaries developed to be fruits, whereas red aril part and normal seeds were not found in the fruits. The fruits had pedicel necrosis and dropped before the harvesting period
