Effect of Phosphorous on Growth and Flowering of Scaevola aemula R.
Br. 'New Wonder'
Scaevola aemula R.Br. (fanflower) is a
popular ornamental plant native to Australia. the cultivar New Wonder is
widely used for hanging baskets and bedding plants. Recently, reduced growth and
low-quality was observed with high phosphorous concentrations. To determine how
phosphorous affects this plant, rooted cuttings were transplanted into 15 cm standard pots
and grown under the 20-P-16.6 (N-P-K) water soluble fertilizer, where P concentrations
were 0, 20, 40, 60, 80, 100, 120 mg@L-1. Growth and flowering data were taken
every three weeks, and the experiment was terminated after 12 weeks. Phosphorous
concentration had significant influence on growth and flowering of New Wonder
fanflower. The length of the longest shoot was slightly reduced at P concentrations of 40
to 60 mg@L-1, and greater reductions occurred at concentrations above 60 mg@L-1.
The number of shoots per plant and shoot dry weight followed the same trend. Number of
flowers per plant was not affected by 0-60 mg@L-1. At concentrations above 60
mg@L-1, flower numbers decreased. Leaf size was reduced by increasing P
concentration. At 20 mg@L-1 P, leaves were more than three times larger than
with 120 mg@L-1 P. To produce better quality plants, 20 mg@L-1 of
phosphorous or lower should be applied at each irrigation. Phosphorous concentration
higher than 60 mg@L-1 should be avoided. Further investigation should be
conducted on the mechanism of how phosphorous affects growth and flowering of Scaevola
aemula New Wonder.
