dc.description.abstract | Flowers of Nymphea stellata Willd., like other water lilies, are subject to circadian clock-controlled petal closure in the afternoon. To investigate the effects of plant growth regulators, and various other chemicals, in arresting nyctinastic movement (petal closure), cut flowers of N. stellata were exposed to different concentrations of gibberellic acid (GA), benzyl amino purine (BAP), naphthalene acetic acid (NAA), abscisic acid (ABA), ethanol, AgNO3, NaCl or Rinso (laundry detergent powder). The most effective treatment to control the biological clock of petal movement was keeping flowers continuously in 25 mg l–1 GA. This treatment kept flowers open, to an acceptable cut flower standard, for over 28 h. Continuous exposure to 5 mg l–1 BAP also kept flowers open to the same acceptable standard for over 15 h. Considering low-cost applications, immersing flowers in 25 g l–1 NaCl for 1 h kept them open for almost 17 h, to an acceptable cut flower standard. Immersing in 2 g l–1 Rinso (Unilever, Sri Lanka) for 1 h also kept flowers open for 14 h in an acceptable condition. By inhibiting nyctinastic closure using any of the above chemicals, N. stellata could now be considered and exploited as a cut flower. | en_US |
