“…However, the contents of phenols and flavonoids decreased when the root tuber matured, but they still had health care value. It may be that these secondary metabolites are transferred after synthesis, and further metabolized or degraded [ 47 ]. Previous studies showed that the content of root elements in sweet potato, cassava and pueraria lobata increased gradually with the development of root [ 20 ].…”

Background Chayote is an underutilized species of Cucurbitaceae. It is rich in nutrients such as protein, minerals, phenols and its extracts have anti-cardiovascular and anti-cancer effects, making it a versatile plant for both medicinal and culinary purposes. Although research on its root tuber is limited, they are rich in starch and have a structure similar to that of potatoes, cassava, and sweet potatoes. Therefore, they can serve as potential substitutes for potatoes and offer promising prospects as agricultural and industrial resources. However, the physiological and cellular mechanisms of chayote root tuber formation and development are still unclear. Results In this study, we observed the growth habit of ‘Tuershao’ (high yield of root tuber). The results revealed that the tuber enlargement period of ‘Tuershao’ lasts approximately 120 days, with the early enlargement phase occurring during 0–30 days, rapid enlargement phase during 30–90 days, and maturation phase during 90–120 days. Physiological indicators demonstrated a gradual increase in starch content as the tuber developed. The activities of sucrose synthase (SUS) and invertase (VIN) showed a consistent trend, reaching the highest level in the rapid expansion period, which was the key enzyme affecting tuber expansion. Moreover, the special petal like structure formed by the secondary phloem and secondary xylem of the tuber resulted in its enlargement, facilitating the accumulation of abundant starch within the thin-walled cells of this structure. Principal component analysis further confirmed that starch content, SUS and VIN activities, as well as the concentrations of calcium (Ca), iron (Fe), and selenium (Se), were the major factors influencing tuber development. Moreover, the low temperature environment not only promoted the growth of ‘Tuershao’ tubers but also enhanced the accumulation of nutritional substances. Conclusions These findings contribute to a deeper understanding of the formation and developmental mechanisms of ‘Tuershao’ tubers, providing valuable guidance for cultivation practices aimed at improving crop yield.
