NAA and STS effects on potted bougainvillea: early flower death allows delayed bract abscission
The effects of Silver Thiosulphate (STS) and Naphtalene Acetic Acid (NAA) (0,45%NAA+1,2% NAA-amide at 500 mg.l) on flowering bud development, anthesis duration, bract longevity and bract photosynthetic rate were studied in Bougainvillea spectabilis ‘Killie Campbell’ plants, under interior conditions. The relationships between bract longevity and the above parameters were also investigated. NAA ...
متن کاملVariability between silver thiosulfate and 1-naphthaleneacetic acid applications in prolonging bract longevity of potted bougainvillea
Potted bougainvillea `Purple Flower' and `Taipei Red' in four different stages of bract development were sprayed with STS (0.1, 0.5 mM) or NAA (25, 50 ppm) and were moved to lowlight indoor conditions after treatment. The experiment was conducted twice, and the results showed that 0.5 mM STS and NAA (25, 50 ppm) could signi®cantly prolong the longevity of bracts at certain stages in both cultiv...
متن کاملThe Influence of 1-Triacontanol on the Growth, Flowering, and Quality of Potted Bougainvillea Plants (Bougainvillea glabra var. “Elizabeth Angus”) under Natural Conditions
Selected physiological and biochemical parameters were monitored at the vegetative and reproductive growth stages in potted Bougainvillea plants treated with five different concentrations of TRIA. Advanced flowering, flower bud number, and blooming rate increased significantly with 0.5 and 1.0 mg/L TRIA treatments. Similarly, photosynthetic rate, pigment content, quantum yield, and stomatal con...
متن کاملPistillate Flower Abscission - 1990
Evaluation of the pistillate flower abscission (PFA) potential of UC-67-13 and UC-67-11 was continued at two sites. At a high PFA site UC-67-13 PFA was only moderately lower than Serr for the third year. UC-67-11 demonstrated low PFA potential for a seconq year at this site. Higher PFA potential of UC-67-13 than UC-67 -11 was also found at a second site for a second year. No further evaluation ...
متن کاملPistillate Flower Abscission (pfa)
PFA was not different with shaded vs. exposed limbs of the same trees nor between shaded interior trees and outside ones with high light exposure. Tehama trees expressed lower PFA than adjacent Serre PFA of Tehama was also low at a site where Serr trees (removed 1982) had very high drop the previous three years. Fruitfulness of all monitored limbs in 1982 ranged from 6 to 97% and the earlier co...
