Nitrogen source determined significant for inflorescence development in Phalaenopsis

Researchers investigated the accumulation and use of fertilizer nitrogen (N) during the vegetative and reproductive growth stages of Phalaenopsis related to inflorescence development. Experiments showed that inflorescence is a major nitrogen sink during the reproductive stage of Phalaenopsis. Fertilizer applied during the reproductive stage was found to be a significant N source for inflorescence development of the orchid, while additional experiments indicated the importance of providing ample N fertilization at all growth stages.
