“…Their leaf water leaching liquid affects root length, shoot length and chlorophyll content, and reduce seed germination and plant dry weight (Talukdar and Talukdar, 2012; Uddin and Robinson, 2017). Allelochemicals reduce plant absorption and increase the availability of soil nutrients (Aslam et al, 2017;Mohammadkhani and Servati, 2018). Our study showed that pine needle water leaching solutions, such as P. tabuliformis, P. thunbergii and P. koraiensis, significantly inhibit their Chl.…”

Two-year-old seedlings of Pinus species typical in North China (Pinus thunbergii, Pinus tabuliformis and Pinus koraiensis) were selected as the research object. The water extracted from the litter of P. thunbergii, P. tabuliformis and P. koraiensis were used to test the changes of photosynthetic pigment Chl. a, Chl. b and allelochemicals. The results were as follows: aqueous extract of P. thunbergii needle litter had significantly low inhibition on P. thunbergii while strongly inhibited P. tabuliformis and P. koraiensis. It also showed a markedly low inhibition on P. thunbergii, a moderate inhibition on P. tabuliformis, and a greatly strong inhibition on P. koraiensis. Obviously strong inhibition on P. thunbergii, P. tabuliformis and P. koraiensis were observed as well. Our study showed that pine needle water leaching solutions, such as P. tabuliformis, P. thunbergii and P. koraiensis, significantly inhibit their Chl. a and Chl. b, and will be a norm, which provides a new explanation for the decline in the coniferous forests of northern China.

“…However, amylase is not the only enzyme involved in germination. Several other enzymes are involved in seed germination; the process is also related to nutrient concentration in the soil (MOHAMMADKHANI & SERVATI, 2018). There are many other mechanisms of 1,8-cineole on wheat seed germination and growth that need further study.…”

Gas chromatography-mass spectrometry analysis of variations in the essential leaf oil of 6 Eucalyptus Species and allelopathy of mechanism 1,8-cineole

The Eucalyptus plant releases allelopathic chemicals into the environment mostly through the essential oils volatilized from the leaves. This study discussed the composition of the leaf oils of few seven-year-old varieties like Eucalyptus pellita (E. pel), Eucalyptus camaldulensis (E. cama), Eucalyptus grandis (E. gra), Eucalyptus dunni (E. dun), Eucalyptus saligna (E. sal), and E. grandis × E. urophylla (E. gra×E. uro) and three-year-old E. grandis × E. urophylla (E. gra × E. uro (three)). It determined the allelopathic mechanism and the types of chemical components playing the leading role. Essential oil was obtained by hydrodistillation and analyzed by the Gas Chromatography-Mass Spectrometry (GC-MS) method. In order to determine the effect of allelopathy, seed germination experiments were carried out at different concentrations (10-100 mL/L) of the E. Gra × E. uro leaf oil (EO) and the major components. The wheat seeds germinated by adding 1,8-cineole were used to determine the activity of α-amylase. Moreover, the mRNA expression of α-amylase in seeds was studied. The major chemical class in the essential oil was oxygenated monoterpene; 1,8-cineole (20.2-67.5%) displayed the highest content. Other substances that were high in content and ubiquitous included α-pinene (0.3-21.8%), α-terpineol (0.44-19.24%), and borneol (0.81-3.05%). The four chemical constituents and EO influenced the germination and growth of the three plants. Among them, 1,8-cineole exhibited the strongest inhibitory effect. The α-amylase activity of the 1,8-cineole-treated wheat seeds had decreased significantly. Molecular evidence suggested that 1,8-cineole decreased the α-amylase gene (AMY) expression.

“…Another important point to consider are soil altering allelopathic effect via modifications of biotic and abiotic soil parameters. Root exudates are known to influence nutrient availability and physicochemical soil conditions and reciprocally (Mohammadkhani and Servati, 2018;Zeng, 2014). By altering the soil properties, it is possible that moor grass allelochemicals may had indirectly affected oak growth.…”
