    The Combination of Achnatherum inebrians Extracts and Soil Microorganisms Inhibited Seed Germination and Seedling Growth in Elymus nutans

    Rui Zhang1, Taixiang Chen1, Zhenjiang Chen1, Hao Chen1, Xuekai Wei1, Malik Kamran1, Chunjie Li1,2,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.3, pp. 567-580, 2024, DOI:10.32604/phyton.2024.047485

    Abstract In a greenhouse experiment, the effects of soil microorganisms and extracts of Achnatherum inebrians on the seed germination and seedling growth of Elymus nutans were studied. The results showed that both the extracts from aboveground and belowground parts of A. inebrians significantly inhibited the germination rate, germination potential, germination index, vigor index, seedling height, root length, and fresh weight of E. nutans, but increased malondialdehyde content, catalase, peroxidase and superoxide dismutase activity of E. nutans seedlings (p < 0.05). The allelopathy of aqueous extracts of the aboveground parts of A. inebrians was stronger than that of the precipitates. Aqueous extracts… More >

    Assessment of the Contribution of Foliar Trichomes towards Allelopathy

    Waseem Mushtaq1, M.B. Siddiqui1, Hesham F. Alharby2, Khalid Rehman Hakeem2,3,*

    Phyton-International Journal of Experimental Botany, Vol.89, No.2, pp. 291-301, 2020, DOI:10.32604/phyton.2020.08740

    Abstract Plant trichomes vary in their structure and cellular composition. Glandular trichomes contain a bulk of specific (secondary) metabolites of diverse nature. Trichomes are connected with various adaptive processes, which include protection against herbivores and pathogens as well. Our study investigates the allelopathic contribution of structures present on the leaf surface of Nicotiana plumbaginifolia Viv. against seedling growth of Cicer arietinum L. The infusion obtained after dipping Nicotiana leaves in Dichloromethane (DCM) for 10 seconds (s) was the most phytotoxic among all the infusions. The observed inhibition in Cicer growth was not only dependent on type of infusion but also the… More >

    The Allelopathic Effects of Sunflower and Wheat Root Exudates on Sinapis arvensis and Sinapis alba

    Bengu Turkyilmaz Unal1,*, Mustafa Bayram2

    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 413-423, 2019, DOI:10.32604/phyton.2019.08244

    Abstract In this study, we aimed to investigate the allelopathic effects of sunflower and wheat root exudates on the common weeds such as wild mustard and white mustard in our region. The root exudates which were obtained by soaking 8 weeks old sunflower and wheat seedlings (20 or 40 seedlings) in 100 mL of distilled water for 3 days were applied to the leaves of wild mustard and white mustard. In order to compare the allelopathic effect, the recommended dose (1 g.da-1 ) and twice the recommended dose (2 g.da-1 ) of Gromstor (Tribenuron-methyl), a herbicide preferred by farmers for the… More >

    Biology of Dittrichia viscosa, a Mediterranean ruderal plant: a review

    Parolin P, M Ion Scotta, C Bresch

    Phyton-International Journal of Experimental Botany, Vol.83, pp. 251-262, 2014, DOI:10.32604/phyton.2014.83.251

    Abstract Dittrichia viscosa is a common plant species in the Mediterranean region which is adapted to a wide range of environmental stresses. It is an important species that can be used for phytoremediation, as bioaccumulator or bioindicator, and it has the potential for being employed in integrated pest management in the Mediterranean ecosystem due to its entomophilous character.

    Allelopathic testing of Pedicularis kansuensis (Scrophulariaceae) on seed germination and seedling growth of two native grasses in the Tibetan plateau

    Shang ZH1,2, SG Xu1

    Phyton-International Journal of Experimental Botany, Vol.81, pp. 75-79, 2012, DOI:10.32604/phyton.2012.81.075

    Abstract Pedicularis kansuensis is a dominating poisonous weed, and it might have allelopathic effects on other native grasses in alpine meadows. An experiment was conducted to examine a range of concentrations of aqueous whole plant extracts (25, 12.5, 2.5, 1.25, 0.25 and 0.0 g/L) of P. kansuensis, prepared at the flowering stage on seed germination and seedling growth of two native grasses (Poa pratensis and Elymus nutans). High concentrations of aqueous extracts of P. kansuensis inhibited seed germination and seedling growth of P. pratensis (p<0.05). Most aqueous extracts of P. kansuensis had a stimulatory (p<0.05) effect on E. nutans. Our results… More >
