“…Results similar to this study were reported by Medeiros et al [20]. These authors evaluated the aqueous extract of São Caetano melon (Momordica charantia L.) and Alamanda Research conducted showed the positive effect of secondary products on the increase in germination percentage and sanitary quality of seeds [21,22,23,24]. The products of secondary order have an advantage over for their implementation in the sanitary control of seeds because they are sustainable, cause less damage to the environment, and in addition to being less costly, are easy to acquire because they come from natural products.…”

This research aimed to evaluate the effects of Clove extract (Syzygium aromaticum) on germination and sanity of Catingueira seeds (Poincianella pyramidalis). Five treatments with Clove extract of India were applied at the following concentrations T1 (Control) = 40 mL of sterile H2O, T2= 10 mL extract + 30 mL of sterile H2O, T3= 20 mL extract + 20 mL of sterile H2O, T4= 30 mL extract + 10 mL of sterile H2O and T5= 40 mL of extract. P. pyramidalis seeds were immersed in due concentrations for 30 seconds, then placed in sterilized Petri dishes and taken to isolation chapel. The sanity test lasted seven days, after this period, the associated microorganisms were evaluated in the seeds. For germination tests, the same treatments used for the health test were used. At the end of the experiment the percentage of germinated seeds, the Germination Speed Index (IVG), Mean Germination Time (TMG), Mean Germination Speed (VMG) and the length of part area and root were calculated. Clove extract (Syzygium aromaticum) showed no toxic effect on germination and development of Poincianella pyramidalis. It was indicated the concentration of 25 and 50% of the extract, because it provided a higher germination percentage, IVG, VMG and TMG to seeds of the species Poincianella pyramidalis. Further studies with immersion time of the seeds higher than those of this research are suggested.

“…The radicle length neutrality observed for M. caesalpiniifolia when submitted to the aqueous extract of A. indica leaves is different from the negative reaction found by Pacheco et al (2017) [65] and Araújo et al (2017) [12], who evaluated the RL of the same species submitted to the extracts of P. moniliformis and C. madagascariensis, respectively. Positive results found for A. urundeuva and C. pyramidale demonstrated that some of the native species tested tolerate low extract concentrations, which allows us to infer that the presence of fresh leaves of A. indica in the field does not interfere with the germination of those species in a negative way.…”

“…This species, which comes from Madagascar, was introduced into the semiarid region and has a high invasive potential [12]. M. caesalpiniifolia showed no GP effect when submitted to the leaf or fruit extracts of P. moniliformis either [65]. As for the rest of the species (A. urundeuva, P. moniliformis, and C. pyramidale) there could not be found any studies which investigated the allelopathic effect on GP and GSI so that their values could be used for comparison.…”

“…In germination tests it is recommended that the pH values of the extracts are in the range of 6.0 to 7.5 as this is the ideal pH range for seed germination and observation of allelopathic effects (Larcher, 2004;Brasil, 2009). Therefore, the pH values obtained in this study are close to neutrality, so as not to interfere in the germination process, since both germination and seedling development can be negatively affected in conditions where the medium is extremely acidic or highly alkaline (Yamashita, Guimarães, Silva, Carvalho, & Camargo, 2009;Pacheco et al, 2017).…”

Studies related to the allelopathic properties of plants have aroused great interest, since species that have compounds with allelopathic activity can be used as bioherbicides in the control of weeds. In this way, the aim of this study was to evaluate the allelopathic action of Dahlstedtia araripensis on the germination and growth of Calotropis procera and Zea mays. The bioassays were prepared using two 50 g portions of leaves, stem bark and D. araripensis roots, and each part of the plant received a hot treatment (1 L of distilled water at 100 °C) and one part cold (1 L of distilled water at 25 °C). The experimental design consisted of six treatments and the control group. The variables analyzed were: Index of Emergency Speed (IES), germinability, length and occurrence of necrotic radicles. The results indicated that the extracts interfered negatively on the germinability of the seeds, mainly on those of C. procera, since all extracts significantly inhibited its germination. In the seeds of C. procera and Z. mays there was delay in IES. The results indicated that the cold and hot extracts of the distinct parts of D. araripensis affected the development of the seedlings, besides promoting root necrosis. The observed effects may be due to the presence of secondary metabolites detected in the different extracts of D. araripensis. However, further research is required to prove the performance of such compounds, as well as their isolation, for future use asnatural herbicides.
