This unfortunate event serves as a poignant reminder of the importance of research, foresight, and proactive measures in addressing the challenges that our world faces today.</p> <p>We aim to revisit the insights shared by our perceptive author and delve into the implications of their warning. The catastrophic floods that recently inundated <strong>Derna</strong> have left a trail of devastation and despair, impacting the lives and livelihoods of its residents. It is during such trying times that the significance of research and knowledge sharing becomes ever more apparent.</p> <p><strong>Join us in acknowledging the vital role of scholars in facing societal challenges and creating a resilient future.</strong></p> <p>You can find the article <a href="">here</a><strong><br /></strong></p> <p><strong>______________________________________________________</strong></p> <p><strong><br />Journal of Pure and Applied Sciences, ISSN: <a href=""><span class="issn">2521-9200</span></a>, publication of Sebha University.

This is considered one of the major problems in successful seed germination. <em>Alhagi graecorum</em> plant is a wild native legume. It has a hard and impermeable testa, which causes physical dormancy of seeds, and to overcome hard coat imposed dormancy, softening the hard seed coat by soaking Hydrochloric acid ( HCl ). The present study was conducted to evaluate various duration of soaking seeds in HCL to breaking physical dormancy for <em> A.graecorum</em> in 10, 20, and 30 minutes. The results showed that, final germination percentage (FGP) in treated seeds significantly increased when compared with the control were 55, 62 and 68 % respectively, while in control was only 12 %. Seed germination influenced by HCL is due to its capability to break the hard seed coat that leads to water absorption and imbibition of seeds. As for the mean daily germination ( MDG ), the results revealed that, there were significance increased in seventh day of sowing in germination between the treated seeds in duration of soaking 20 and 30 min were 23 and 24 % respectively, as they were most effective in germination, while the germination in the control stopped in the fifth day of sowing at 12 %. While the mean germination time (MGT), the results indicated that the seeds soaked in acid recorded 9.66, 9.13, and 8.62 days, respectively. The minimum MGT for treated seeds was detected in 30 min., 8.62 days. The reason for the long period of the mean germination time may be due to the use of a low concentration of hydrochloric acid, so I recommend using higher concentrations of acid to obtain a lower mean germination time.</p> 2023-08-07T00:00:00+02:00 Copyright (c) 2023 Journal of Pure & Applied Sciences
