"An experiment was conducted to observe the inhibitory effects of the leaf extracts derived from Albizialebbeck (L.) Benth. on germination and growth behavior of some popular agricultural crops (receptor) of Bangladesh. Experiments were set on sterilized petridishes with a photoperiod of 24 h at room temperature of 27–30°C. The effects of the different concentrations of aqueous extracts were compared to distil water (control.). The aqueous extracts of leaf caused significant inhibitory effect on germination, root and shoot elongation and development of lateral roots of receptor plants. Bioassays indicated that the inhibitory effect was proportional to the concentrations of the extracts and higher concentration (50%–100%) had the stronger inhibitory effect whereas the lower concentration (10%–25%) showed stimulatory effect in some cases. The study also revealed that, inhibitory effect was much pronounced in root and lateral root development rather than germination and shoot growth [Uddin, Mohammad & Ahmed, Romel&Mukul, Sharif & Hossain, Mohammed. (2007). Inhibitory effects of Albizialebbeck leaf extracts on germination and growth behavior of some popular agricultural crops. Journal of Forestry Research. 18. 128-132. 10.1007/s11676-007-0025-9.]" https://www.researchgate.net/publication/226170916_Inhibitory_effects_of_Albizia_lebbeck_leaf_extracts_on_germination_and_growth_behavior_of_some_popular_agricultural_crops |

"The seed of okra (Abelmoschus esculentus L.) Moench] have slow and poor germination when seeds are sown in early spring season due to low temperature. Laboratory experiment was conducted to study the effect of seed priming using plant extract on seed quality characters of okra. Various botanical leaf extracts used like Arjuna, Bael, Harad, Bahed, Arrapu, Neem, Reetha, Amla, Tulsi, Prosopis and Cow urine on seedling quality characters of phulevimucta variety of okra. The result concluded that priming with Arrapu (Albiziaamara) Leaf Extract at (3%) for 12hrs increased the germination and seed vigour in Okra. Its exhibited high mean value for Seedling characters like seed germination percentage (96.50%), Speed of germination (09.77), root length (12.22cm), shoot length (16.39cm), seedling length (28.80), seedling fresh weight (1.03gm) and seedling dry weight (0.35gm), seed vigour index I (2427.95) and seed vigour index II (19.36)." https://www.ijcmas.com/8-8-2019/Indrajitsingh%20P.%20Girase,%20et%20al.pdf |

Fire is a known to be a germination stimulant for some species of plants, particularly trees and woody plant species native to fire prone areas in South Africa, Australia, and the Western US. Research also indicates that in some plants it is not the heat from fire, but chemicals in smoke that stimulate germination. A compound called butenolide in smoke is thought to be involved in this effect. Exposure to smoke can result in improved germination, including faster germination rate and improved seedling vigor in some species. This is still experimental, and more research is needed to fully understand how best to use smoke treatments to improve germination. If you wish to try smoke treatment at home, start with a 1% liquid smoke solution and soak seed 6 to 24 hours before sowing. Use an “all natural liquid smoke, like Wright’s, for the solution. To easily make a gallon of smoke solution very close to 1% concentration, add 3 tablespoons of liquid smoke to a gallon of water. |
