Effects of Different Treatments on Seed Germination Improvement ofCalotropis persica

Abstract

The purpose of this study was to investigate the effects of different treatments on seed germination in the desert plant speciesCalotropis persica(Gand.). This species is known to have long time for seed germination considering arid region condition and short time of access moist. An experiment was performed with 13 treatments and 4 replications in a completely randomized design. Treatments included KNO3with concentrations of 0.1, 0.2, and 0.3 percent, immersion in hot water for five min, acetylsalicylic acid 100, 200, and 300 mg L−1, ethereal sulfuric acid (60%) for 5 and 10 min, thiourea with concentrations of 0.1% and 0.3%, and prechilling for 10 days. Tap water was used as the control. Our findings indicate that KNO30.1% and 100 mg L−1acetylsalicylic acid were the most effective treatments for improvement of seed germination properties in this species. In a comparison of the two mentioned treatment, KNO30.1% treatments is the best.

Seed Germination of Gundelia Tournefortii L. Under Different Dormancy Breaking Treatments

“…But, the highest value of mean germination time was recorded by seed soaking in boiled water for 60mintes. The results partially similar to those obtained by Farajollahi et al, (2014) concerning Calotropis persica plant, Tania et al, (2019) concerning Momordica charantia L. plant and Usman et al, (2010) concerning Acacia senegal plant.…”

Effect of Pre-Sowing Treatments on Mamalis (<i>Pittosporum pentandrum</i> Blanco Merr.) Seeds Germination under Nursery Condition

“…The spatial distribution of germination is generally controlled by seed and fruit morphology, which improves offspring dispersal from the maternal habitat [15]. Seed germination is the critical stage for species survival [16]. Seed germination is a period in the life cycle of a plant when growth is temporarily suspended or very minimal to the point of undetectable visibility.…”

Effects of Different Pretreatments and Seed Coat on Dormancy and Germination of Seeds of Senna obtusifolia (L.) H.S. Irwin & Barneby (Fabaceae)

“…The germination varied from 4.17% to 8.50% (Figure 1d), while the (Asghar et al, 2014), Medicago species (Hamid & Seyed, 2006), Gmelina arborea (Mensah & Agbagwa, 2004), Capsicum frutescens L (Mensah and Agbagwa, 2001). …”

“…The germination of the seeds of S. obtusifolia has continued to be problematic and the seeds may require different scarification methods and exogenous treatments with chemical to break dormancy and enhance germination, as have been reported for other species (Tambari & Aminu, 2015;Al-Menaie, 2010;Ramamoorthy, 2005;Rolston, 1978;Nalawadi, 1977;Asghar, Ali, & Mozhgan, 2014;Emongor, Mathowa, & Kabelo, 2004;Irfan et al, 2013;Ajiboye, 2010;Idu, Omonhinmin, & Onyibe, 2007;Salehi, 2008;Corbineau, Gouble, Lecat, & Come, 1991;Asghar et al, 2014;Mohammad , Faezeh, & Vajihe, 2014;Gregorio, José, & Pedro, 2012;Yushi, Kouhei, Tomoya, Takashi, & Mari, 2008). Studies on pre-treatment methods to break dormancy in S. obtusifolia seeds have not received desired attention.…”
