Plant-derived smoke has been known to play an important role in distribution and growth of vegetation. Using a proficiently designed furnace, we extracted smoke from the leaves of four plant viz. ,,, and . Smoke dilutions obtained from these plants were obtained in different concentrations to identify potential lettuce growth promoting smoke solution. Results revealed that smoke obtained from significantly enhanced the lettuce seed germination. This solution was then partitioned into ethyl acetate, dichloromethane, -hexane, chloroform and ether fractions. Ethyl acetate fraction was found to be potent to enhance seed germination. This fraction was subjected to column chromatography and spectroscopic techniques to obtain compound . This compound was identified as hydroquinone using 1D and 2D NMR techniques. At low concentrations (5, 10, and 20 ppm), compound enhanced the lettuce seed germination; however, higher concentrations inhibited its growth as compared to control.

Root parasitic broomrape ( and spp.) weeds cause devastating damage to agricultural production all around the world. The seeds of broomrapes germinate when they are exposed to germination stimulants, mainly strigolactones (SLs), released from the roots of any plant species; however, broomrapes parasitize only dicot plants.

Mowing is a primary practice in temperate meadows, which are severely degraded due to frequent mowing, overgrazing, and other factors, necessitating restoration and sustainable management. The natural recovery of these grasslands hinges on their germinable soil seed banks, which form the basis for future productivity. Thus, germinable soil seed banks are critical for restoring overexploited meadows.

Obligate root parasitic plants of the Orobanchaceae family exhibit an intricate germination behavior. The host-dependent germination process of these parasites has prompted extensive research into effective control methods. While the effect of biomaterials such as amino acids and microRNA-encoded peptides have been explored, the effect of double-stranded RNAs (dsRNAs) has remained unexamined during the germination process.

We report a green approach to prepare carbon dots (CDs) with fresh tomatoes as carbon sources and amino acids as dopants (ACDs) by a microwave assisted method. The synthesised CDs were analysed by UV-visible absorption spectroscopy, photoluminescence spectroscopy, high resolution transmission electron spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photo electron spectroscopy. An MTT assay was used to evaluate the cytotoxicity of CDs toward L929 cells and found that CDs exhibit low cytotoxicity.

Oryza sativa is one of the most important crops and a food source for billions of people. Anthropic global warming, soil erosion, and unstable environmental conditions affect both its vegetative and reproductive growth, and consequently the final yield of its cultivation. The reproductive phase starts with the transition of apical meristem from vegetative to reproductive, which develops into a panicle, proceeds through the differentiation of the floret, and, after fertilization, the filling of the grain.
