“…The root length of the germinated seeds was more sensitive to allelochemicals compared to the shoot, which was reflected in the percentage of inhibition of germination and the phytotoxicity index. Such effect could be expected, considering that roots first absorb allelochemicals and then transfer them to shoots that is confirmed in previous studies (Turk and Tawaha, 2003;Sarkar et al, 2012). Seed vigor is an important parameter for testing seed quality.…”

In this study allelopathic effects of essential oils from English lavender (Lavandula angustifolia) and creeping thyme (Thymus serpyllum) on seed germination and seedling growth of mint (Mentha spicata), lemon balm (Melissa officinalis), tomato (Lycopersicon esculentum), cucumber (Cucumis sativus), and black locust seeds (Robinia pseudoacacia) was evaluated. The assessment of the allelopathic effect of essential oils was examined in a laboratory biological test. Working solutions of essential oils were prepared in three concentrations (10, 20 and 30 mg/mL). Both oils exhibited allelopathic effects, however, the concentrations that exhibited suppressing effects were different among the plants. It was noticed that English lavender and creeping thyme oils reduced the germination and growth of mint and black locust seeds and significantly suppressed tomato seed germination at higher concentrations (20 and 30 mg/mL), while it increased the lemon balm seed germination.

“…RWC (relative water content), height, spike length, number of spikelets per spike, and 100 grain weight of the wheat plants raised with the leachates of dry leaves and flowers of Tagetes erecta L. exhibited a slight increase at lower concentrations of 1% w/v, whereas a decrease was recorded at higher concentrations of 10% w/v. A decrease in relative water content has been reported earlier in Brassica campestris L. (mustard) treated with aqueous extracts of the roots, leaves, and seeds of Cassia tora L. by Sarkar et al. (2012) .…”

Differential activity of wheat antioxidant defense system and alterations in the accumulation of osmolytes at different developmental stages as influenced by marigold (Tagetes erecta L.) leachates

Experiments were conducted to evaluate the effectivity of Tagetes erecta L. leachates on various growth, physiological, and biochemical parameters of wheat at different stages of growth. Results suggested that Triticum aestivum L. seedlings/plants when exposed to higher concentrations of marigold leachates (10%, 20%, and 30% w/v of fresh parts and 5% and 10% w/v of dry parts) exhibited enhanced lipid peroxidation along with an increase in the activity of protease and phenylalanine ammonia lyase. Treatment with higher concentrations of leachates of fresh (30% w/v) and dry (10% w/v) T. erecta upregulated the activity of superoxide dismutase, catalase, ascorbate peroxidase, guaiacol peroxidase, glutathione S-transferase, and glutathione reductase and also increased the non-enzymatic components of antioxidant defense such as glutathione, ascorbic acid, and total phenols along with osmotic constituents comprising free proline, free sugars, and free amino acids in wheat. The growth and yield attributes of wheat exhibited a slight increase at treatments with lower concentrations (1% w/v) of dry leachates, whereas a decrease was recorded at higher concentrations (10% w/v). In general, treatments with flower leachates (higher concentrations) showed greater influence as compared with those with leaf leachates. Identification and understanding the mechanism of function of allelochemicals in these leachates may pave a way for further experimentation on Tagetes erecta L crop while it is cultivated and decomposed in the field.

“…The root tips were hydrolyzed in 1 mol/l HCl for 20 min at room temperature and then stained with 2% acetyl carmine solution for 1 h (Qian et al 1998). Chromosome diffusion was prepared using extrusion technology according to the method of Savaskan and Toker (1991). The mitotic index (MI) from 500 cells was studied at different times.…”

It is well known that salicylic acid (SA) can help plants tolerate abiotic stresses. Nevertheless, the regulatory functions of SA in plants, such as the response of Fritillaria hupehensis Hsiao et K.C.Hsia to exogenous SA rational application under heavy metal stress, remain unknown. This study aimed to assess the relief effects of SA on the damage of F. hupehensis caused by heavy metal cadmium (Cd), as measured by physiological and biochemical characteristics. The results showed that bulb germination and seedling growth of F. hupehensis Hsiao et k. c. Hsia decreased under different Cd toxicity treatments. The radicle length and mitotic index also significantly decreased under Cd stress (P < 0.05), especially under high concentrations of Cd stress. The bulb germination and seedling growth increased slightly under medium concentration treatment compared to low concentration treatment. Cd toxicity treatment significantly reduced the contents of pigment, protein, and sugar in seedlings compared with the control. The contents of total antioxidants and malondialdehyde in Cd-poisoned seedlings increased significantly. The comprehensive treatment promoted the growth of bulbs and seedlings. As a result of Cd stress, SA application significantly increased the bulb germination rate, radicle length, mitotic index, pigment, protein, and sugar content. Lipid peroxidation and total antioxidants were decreased by comprehensive treatments compared with Cd toxicity treatment. This simple study remarkably broadened our understanding of the application and protection of SA in Cd stress. Bangladesh J. Bot. 52(2): 601-606, 2023 (June) Special
