“…This is consistent with the 11%, 28% and 61% increase in chlorophyll content observed in rice (Oryza sativa) plants after 1, 2 and 3 foliar applications of 1:500 wood distillate, respectively [4]. Similarly, chlorophyll increases > 50% compared to controls were observed in 4-week-old rice seedlings after priming seeds with 1:100, 1:300 and 1:1000 wood distillate [5]. In addition, mustard (Sinapis arvensis) plants grown in soils added biweekly with 1:500 wood distillate showed increases in chlorophyll content of ca.…”

“…Wood distillate, also known as pyroligneous acid or wood vinegar, is one of these bio-based products which is empirically known for providing several benefits to agricultural plants, e.g., limiting the action of pathogens and increasing their productivity [3]. Among the most investigated effects related to the application of wood distillate to plants is the increase in biomass [4,5] and in the number of fruits along with their size [6,7]. In addition, also positive effects on the chlorophyll content and the photosynthetic rate are reported [4,8].…”

This study investigated the effectiveness of foliar application of sweet chestnut wood distillate on the photosynthetic performance and growth of lettuce (Lactuca sativa L. cv ‘Canasta’), both alone and in combination with soybean lecithin used as biosurfactant. Seedlings of lettuce were treated with a foliar application of either mineral water (control), or 1:500 solutions of 3% soy lecithin, wood distillate and wood distillate plus 3% soy lecithin. After 1 week, the chlorophyll content, chlorophyll fluorescence, chlorophyll reflectance and dry biomass were measured. The results showed that both wood distillate and lecithin exerted a positive effect on chlorophyll content and biomass production, but the joint use of wood distillate and lecithin quickly stimulated a ca. 50% increase in these parameters and is thus recommended.

“…Treat-ing seeds with wood vinegar also has the effect of improving crop resistance. Seed soaking in a wood vinegar solution can significantly increase the content of abscisic acid and the activity of antioxidant enzymes in the roots of wheat under drought conditions by reducing the content of malondialdehyde, and thus improve the drought resistance of wheat [26] and reduce the damage of salt stress to rice seedlings [48]. These studies have confirmed that wood vinegar can increase the antioxidant capacity by enhancing the activity of antioxidant enzymes such as superoxide dismutase and regulate the content of osmotic substances such as proline and soluble protein to reduce the osmotic potential of cells and reduce cold stress.…”

Wood vinegar is formed by the condensation of smoke produced during the production of biochar. It mainly contains acetic acid, butyric acid, catechol, and phenol. Wood vinegar has a compound effect of promoting crop growth similar to plant growth regulators and is environmentally friendly. Moreover, it can enhance the biological and abiotic resistance of crops. In this study, foliar spraying was carried out systematically in the field with the hybrid variety of Huayouza 9 for two years to study the effects of wood vinegar and its compounds on the growth of rapeseed (Brassica napus L.). We applied four treatments with tap water as a control (CK), namely wood vinegar diluted 400-fold (M), M mixed with gibberellin (T1), M mixed with sodium D-gluconate (T2), and M mixed with melatonin (T3). They were sprayed in the seedling stage and overwintering stage, respectively. The results showed that the seed yield, the leaf area index, and the number of pods per plant of rapeseed treated with M increased by an average of 9.58%, 23.45%, and 23.80% in two years as compared to the CK, respectively. Compared with M, the seed yield of rapeseed treated with T1, T2, and T3 increased by an average of 7.88%, 6.90%, and 1.32% in two years, respectively. The treatments also improved the quality of rapeseed. In particular, the glucosinolate content of rapeseed treated with T2 and T3 decreased by an average of 12.83% and 6.72% in two years compared to the CK, respectively. The four treatments selected in the current study improved the resistance of rapeseed at the low temperature of 2–6 °C by increasing the activity of superoxide dismutase and proline and soluble protein contents, as compared to the CK. Besides, all treatments containing M reduced the incidence of Sclerotinia sclerotiorum and Peronospora parasitica (downy mildew) in rapeseed. More specifically, the T3 treatment significantly decreased the infection rate of these two diseases mentioned above by an average of 17.33% and 12.14% in two years compared to the CK, respectively. Therefore, the study and application of wood vinegar due to its compound effects on crop growth and yield is of great importance to sustainable agriculture, crop ecology, and environmental protection.

Deterioration of seeds is an important problem leading to low germination and uneven crop establishment causing poor crop growth and productivity. Soil salinity is another factor limiting crop cultivation. Spermidine (Spd) is a compound widely reported for diminishing adverse effects of salt stress in plants. In this study, the effects of Spd priming on normal and deteriorated rice seeds were investigated under salt stress during germination and young seedling stages. Rice seeds were primed with H2O and Spd solutions for 24 h before germination. All rice seeds were grown in Petri dishes containing 5 ml of deionized water with 0 (control) or 150 mM NaCl (salt treatment) for 1-10 d. The results showed that priming groups had higher germination percentage (GP) and germination index (GI) in both normal and deteriorated seeds. Moreover, deteriorated seeds primed with 0.5, 1.0 and 1.5 mM Spd showed significantly higher GP and GI than H2O-primed and non-primed seeds. During early hours of hydration, Spd-primed seeds produced reactive oxygen species (ROS) faster and at higher level than non-priming and H2O priming groups in both control and saline conditions. Earlier accumulation of ROS was associated with more rapid germination. In young seedlings, salinity stress caused a marked decrease in growth and increased membrane damage indicated by higher malondialdehyde (MDA) and electrolyte leakage (EL). Conversely, Spd priming increased growth and reduced membrane damage of rice seedlings established from normal and deteriorated seeds under salt stress. The finding suggested that Spd priming can effectively improve germination of deteriorated seeds and enhance seedling growth under control and salt stress conditions.
