| This experiment was carried out to find optimum ratio of $NO_3^-$ to $NH_4^+$ in nutrient solution for the growth of Phalaenopsis hybrid and find the effect of the ratio of $NO_3^-$ to $NH_4^+$ on the flower stem (inflorescence) quality. The ratio of $NO_3^-$ to $NH_4^+$ of nutrient solution used in this experiment was 100% : 0%, 90% : 10%, 80% : 20% and 70% : 30%. Phalaenopsis showed better growth when $NH_4^+$ was supplied concurrently with $NO_3^-$ as nitrogen source than supplied with only $NO_3^-$. Especially, increasing the ratio of $NH_4^+$ from 0% to 10% the fresh weight and dry weight of Phalaenopsis hybrid was highest. But, the growth of shoot and root was diminished when the proportion of $NH_4^+$ in nutrient solution was increased from 10% to 30%. Inflorescence length, the number of inflorescence and flower per plant all increased as $NH_4^+$ increased from 0% to 10% but, decreased from 10% to 30%. These results suggest that the optimal ratio of $NO_3^-$ and $NH_4^+$ in nutrient solution for the growth of Phalaenopsis including inflorescence was founded to be 90%:10%. |
