Oncidium on 15 hrs light period and night break treatments exhibited heavier fresh and dry weights, lower total soluble sugar content in pseudobulb because nutrient translocated for inflorescence development, however water content was no significantly different. After treatment of 9 hrs and 12 hrs light period, the total soluble sugar content in pseudobulb of Oncidium was higher than other treatments because of consuming less nutrient transfered from pseudobulb due to poor inflorescence development and the quality of inflorescence also showed worse.

以15小时电照周期处理与暗期中断处理之植株乾鲜重较重，含水量则无明显差异，而假球茎内的全可溶性糖含量则较其他处理组低，因为花序发育时，假球茎内的碳水化合物转移到花序，以提供花序发育所需之养分。9小时电照周期处理组与12小时电照周期处理组方面，因为其花序品质较差，消耗的养分较少，故其假球茎内的全可溶性糖含量较高。
