“…Among the many applications of plant performance studies in a stress environment, the Chl a fluorescence technique has been employed as a tool for the development of new substances with photosynthesis inhibitory action (King-Díaz, B. Soares, M. , G. F. da Silva, M. , Lotina-Hennsen, B. and Veiga, 2014;Mendes et al, 2019;Veiga et al, 2013). The effects of photosynthetic apparatus on a number of compounds as well as synthetic compounds has been studied.…”

Eight p-benzoquinones derivatives (1-8) were synthesized and evaluated as photosynthesis and plant growth (dry biomass) inhibitors through semi in vivo and in vivo assay. The photosynthetic parameters provided by the JIP-test were based on the major steps of the photosynthetic process: photon absorption (ABS), energy capture (TR), electron transport (ET) and reduction of photosystem II (PS II) final acceptors (RE). Compounds 6, 7 and 8 decresead the PI(abs) parameter by 82, 75, 42% and incresead the ET0/CS0 parameter by 37, 20 and 25%, respectively. These results suggested that 6-8 inhibit the electron transport chain at PS II in both semi in vivo and in vivo assays. Futhermore, compounds 6 and 7 reduced the plant growth by 52 and 77%, respectively. Therefore, the derivatives of p-benzoquinone not only demonstrated appreciable activity as inhibitors of photosynthesis by acting on the electron transport chain on the acceptor side of PS II, but also inhibit the plant growth.

Four compounds were isolated from roots and aerial parts of Pluchea sagittalis (Asteraceae), 3, 5-dihydroxy-6, 7, 3', 4'-tetramethoxiflavunol (1), 5-hydroxymethylfurfural (2), 3, 4-dimethoxybenzaldehyde (3) and 2, 3, 4-trihydroxybenzaldeyde (4). Their herbicidal potential was detected by polarographic techniques. All of them inhibited the non-cyclic electron transport on basal, phosphorylating and uncoupled conditions from HO to methylviologen (MV); thus, they act as Hill reaction inhibitors. Studies on fluorescence of chlorophyll a (ChL a) indicated they have different modes of interaction and inhibition sites on the photosystem II electron transport chain; 1-3 have interacted with the acceptor side while 4 has interacted at the donor side.
