Effects of red and blue light ratio on the morphological traits and flower sex expression in Cucurbita moschata Duch.

Squash (Cucurbita moschata Duch.) is an important fruit vegetable that can be long-term transport and storage. Light-emitting diodes (LEDs) are commercially used light sources applied to improve the producing of leaf vegetables in plant factory. However, influences LEDs on growth flower development remain unknown. In this study, five effective quality treatments, including white light, a 10:8 ratio blue (B) red (R) 10:4 mixture blue/red were for growing squash inducing female flowers maximize production. Our results show varying influence morphological traits appearance. Both improved first second internodes induced larger leaves petiole lengths, whereas caused shorter heights decreased internode lengths. Although treatment reduced chlorophyll content, spectral regime increased number influenced sex development, more fruits. Light manipulation thus beneficially proportion plants. plants under exhibited increase yield, as supplementary
