Figure 1:
(A) Resembles the staminate flower of a cucumber sprayed with ethrel at the cotyledonary stage with a slight modification on its basal part highlighted with a red circle compared to (B) a normal staminate flower of a cucumber without the application of ethrel.
Figure 2:
Cucumber seedlings in 4 days after application of different plant growth regulators at the cotyledonary stage. (The cucumber seedlings exhibited varied responses at cotyledonary stage applied with plant growth regulators in which paclobutrazol (PBZ), 6-Benzylaminopurine (BAP), ethrel, application resulted in shorter seedling’s height in average (5,6,5.5 cm long respectively). Seedlings treated with 1-Naphthaleneacetic acid (NAA) showed expanded and bent stems. Gibberellins (GA3) application and control were most likely similar in appearance).
