Activation of growth and nodulation in a symbiotic system between pea plants and leguminous bacteria by near-UV radiation

Significance of flavonoids in plant resistance: a review

“…UV-B was also shown to induce the production of flavonols in silver birch and grape leaves (Tegelberg et al 2004;Kolb et al 2001 UV (300-400 nm) increased flavonoids in the roots of pea plants (Shiozaki et al 1999). The treatment also promoted the net photosynthesis and enhanced growth (shoot length, fresh weight).…”

Influence of abiotic stress signals on secondary metabolites in plants

“…85 UV (300-400 nm) increased flavonoids in the roots of pea plants. 86 UV-B was also shown to induce the production of flavonols in silver birch and grape leaves. 87 Moreover, under six different daily doses of UV-radiation (UV-A and UV-B), photosynthetic pigments, condensed tannins were accumulated whereas its precursor, (+)-catechin, decreased significantly.…”

Compulsory winding in the opposite direction of climbing plants promotes yield

“…This result suggests that the compulsory sinistrorse-winding enhances the level of flavonoids in the roots of kidney bean plants. According to Shiozaki et al [22], the level of flavonoids in the pea roots is associated with the nodulation on the pea roots and besides The asterisks indicate a significant difference between dextrorse-and sinistrorse-winding at P < 0.01 (**) and P < 0.05 (*) by the t-test (n = 10). Error bars represent S.E.…”
