Relationship between Flower Color and Cellular Physicochemical Factors in Bletilla striata

Flower color not only determines the quality and commercial value of ornamental plants, but it also plays a vital role in ecological processes such as pollinator attraction. This study aimed to investigate relationship between flower cellular physicochemical factors Bletilla striata. The space values 21 samples were initially determined, followed by selection five with significant differences for testing cell shape, total flavonoid content (ranging from 1.86 5.42 mg/g), anthocyanin 0.52 292.62 (A530 − 0.25 ∗ A657)/g), pH (varying 5.03 5.74), metal ion (including Al3+, Ca2+, Fe3+, K+, Mg2+, Na+, P5+, Zn2+, Mo6+, Cu2+, Mn2+). flowers predominantly purple, pink, yellow; distributed quadrants I, II, IV on a* b* rectangular coordinate. was identified primary indicator this species. Total Zn2+ showed positive correlation a*, while Mn2+ demonstrated negative correlations. Cell content, had nonsignificant correlations a*. In conclusion, ions play crucial roles determining B. striata, which can have implications Future research should focus understanding complex interactions these develop novel plant varieties desirable colors enhanced functions.
