AI Article Synopsis
- The corm size of Crocus sativus, crucial for stigma harvesting, can be enhanced by potassium (K) application during water culture experiments.
- Increased K concentration leads to higher chlorophyll content, ATP levels, and photosynthesis rates in the leaves, improving their metabolic function as a source.
- Additionally, higher K levels also boost nutrient absorption and growth in new-born corms, strengthening their role as a metabolic sink, ultimately promoting overall corm growth.
Article Abstract
The corm size of Crocus sativus, a well-known medicine, is a key limiting factor for its stigma harvest. A water cultural experiment with four different potassium (K) concentrations showed that the K content, chlorophyll content, relative ATP content and net photosynthetic rate in C. sativus leaves increased with improving K concentration, which enhanced the function of leaves to be metabolic source. On the other hand, the K absorbing ability and the contents of soluble sugars, vitamin C (Vc) and protein in new-born corms were increased with improving K concentration, which also strengthened the function of new-born corms to be metabolic sink. This study also showed that K could promote the new-born corm growth rate of C. sativus through strengthening the function of "source" and "sink".
