Abstract:
As the base of the spathes usually turns green seasonally when the anthurium is cultivated under the shade in Hainan.For inhibiting the appearance the “Green Ear”,the effects of different concentration of nitrogen on the spathe coloration,the contents of pigments,soluble sugar and protein,as well as the mineral element were investigated in the spathes of potted cultivar ‘Dakota’.The results showed that the lower concentration of nigrogen (0-0.20 g/L) was helpful to reduce the incidence rate of “Green Ear”,and increase of a* and C* value of the base and middle part of the spathes.The total anthocyanin content was higher while the chlorophyll content was lower in the spathe when treated with lower concentration of nigrogen.Besides,the nitrogen content elevated while the potassium and phosphorus contents dropped with the increasing of nitrogen concentration treatment.With the growing states into the consideration,it showed that the irrigation concentration of nitrogen could be controlled within 0.10-0.20 g/L,which was benefit for the inhibition of the appearance of “Green Ear” of anthurium spathe in Hainan.
