The Effect of Seed Priming Applications on Germination Parameters of Red Clover (Trifolium pratense L.)

Abstract

This study aimed to determine the effects of silicon (Si) and salicylic acid (SA) seed priming applications on the germination parameters of red clover (Trifolium pratense L.). The study was carried out in Siirt University, Faculty of Agriculture, Field Crops Laboratory, under controlled conditions at 24±1 °C. The plant material of the study was Rajan red clover (T. pratense L.) cultivar. The laboratory study was carried out in Petri dishes according to the randomized plots trial design with 4 replications. The subject of the study consists of hydropriming application with 2 mM, 4 mM, and 6 mM priming doses of Si and 0.5 mM, 1.0 mM, and 1.5 mM priming doses of SA. The study also included the non-priming application as a control subject. The germination percentage, mean germination time, germination index, coefficient of uniformity of germination, and germination energy properties were examined in terms of the effect on germination development in different priming applications applied to red clover. Significant differences were found between the priming applications in terms of all germination parameters examined. It is thought that early germination, more uniform germination, and higher germination rate can be achieved with priming applications in plants with germination problems such as red clover. In this respect, 2 mM Si priming application can be recommended.

Screening of lentil genotypes during germination and early growth stages under PEG-induced drought stress

“…Germination percentage (GP), mean germination time (MGT), germination index (GI), uniformity of germination (UG), germination energy (GE) and water content (WC) were calculated depending on counting daily germinated seeds. Germination characteristics were calculated with equations that were used by Özyazici and Acikbas (2021). The observations were taken from 10 plants randomly selected from the germinated seeds in each petri dish.…”

Effects of Salicylic Acid Priming Application in Some Switchgrass (Panicum virgatum L.) Cultivars

“…Salicylic acid, a natural phenolic compound and a phytohormone (Farooq et al, 2008; Singh and Gautam, 2013; Souri and Tohidloo, 2019), has been reported to play important roles in enhancing plant tolerance to various abiotic stresses (Maghsoudi et Özyazıcı and Açıkbaş, 2021). Salicylic acid also serves as a significant regulator in various physiological processes such as the uptake and transportation of plant nutrients (Hayat and Ahmad, 2007;Farooq et al, 2008;Maghsoudi et al, 2019), the biosynthesis of various enzymes (An and Mou, 2011), stomatal movements (Khan et al, 2003;Hayat and Ahmad, 2007), respiration and photosynthesis (Hayat et al, 2005;Farooq et al, 2008;Janda et al, 2014), sugar metabolism (Dong et al, 2011), and antioxidant enzyme activity (Singh and Gautam, 2013;Torun, 2019).…”

Potassium and Salicylic Acid Fertilization Effects on Productive and Qualitative Traits of Cyamopsis Tetragonoloba Under Drought Stress

“…According to its biochemical properties, any kind of nutrient can influence plant growth and yield (Nouri et al, 2020.b).. Salicylic acid (SA) is a phenol-based phytohormone and regulates vital plants' physiological processes, particularly water uptake and ion transport, transpiration, and photosynthesis (Klessig et al, 2018). SA interacts with other signaling molecules and thus regulates various physiological and morphological responses in plants (Iqbal et al, 2021) and increases protection against abiotic stress (Özyazici and Açikbaş, 2021). SA has been reported to increase calcium, magnesium, and potassium levels in shoots and roots in dry conditions, which can reduce the harmful effects of drought stress on plants (El-Tayeb and Ahmed, 2010).…”
