“…Also, it seems that an increase in germination percentage is due to the impact of PGPR on increasing is the production of some hormones particularly GA and cytokinin (Demidchik Grosskinsky et al 2016). GA by activating some of the enzymes such as α-amylase that are involved in starch metabolism affected the germination (Kaymak et al 2009). In research, Ghezal et al (2016) found that seed pretreatment alleviated the inhibitory effect of salt stress of pea germinated seeds.…”

Cumin (Cuminum cyminum L.) is the second most popular spice in the world, after black pepper, which is sensitive to salinity. In order to investigate the effect of seed bio-inoculation with plant growth promoting Rhizobacteria on germination and seedling indices of cumin under salinity stress, an experiment was laid out based on a completely randomized design with two factors and four replications in 2017 at Seed Science and Technology Laboratory, Yasouj University, Iran. Experimental factors included bio-inoculation with 3 strains, viz. PF2, PF25, and CHA0 of Pseudomonas fluorescents, and Bacillus subtilis and non-primed (control) and three levels of salinity stress (0, -4 and -8 bar). Results indicated that salt stress reduced germination (up to 40%) and seedling indices of cumin under -4 and -8 bar, the highest germination percentage, germination rate, seedling length, and seedling vigor index were achieved in the seeds inoculated with P. fluorescens, CHA0. At all levels of stress, seed bio-inoculation were increasing the seed soluble protein content compared to non-primed. The effect of this treatment was more obvious under salinity potential of -8 bar. The results indicated that salinity can affect cumin seed germination and the beneficial effect of PGPR could be used for improving its salt tolerance.

Pathway among fatty acid profile, seed germination, and vigor of watermelon cultivars

Watermelon (Citrullus lanatus) seed is rich in oils and the fatty acid composition of watermelon seeds is a significant source of nutrition and income for especially Africa, the Middle East, and Asia countries. Although the fatty acid profile of watermelon seed is well documented, the underlying associations with seed traits have not yet been studied. Therefore, the current study aimed to determine both fatty acid profile of watermelon seeds and the relations between the fatty acid profile and seed/seedling characteristics. For this purpose, two common watermelon cultivars (Alaska F1 and Galaktika) of seed were used to examine the first count, germination percentage, vigour, vigour index, seed coat ratio, 100-seed weight as well as fatty acid profile. Vegetative traits including seedling height, diameter, dry matter, and leaf area were also determined in these cultivars. As a result, there were significant differences among cultivars for vigour, vigour index, seedling height, seedling diameter, and fatty acids. In addition, linoleic (C18:2n-6) (68%), oleic (C18:1n-9) (15%), and palmitic (C16:0) acids (9.7%) were considerably highest in concentration in the watermelon seeds. The correlation analysis showed that palmitoleic acid (C16:1n7) and arachidic acid (C20:0) in watermelon seeds could play an important role in signalling seed and seedling traits. Also, seedling dry matter can be used indicator of a large number of fatty acids based on the correlation results. According to principal component analyses, among several fatty acids, C16:1n-7, C18:1n-9, and monounsaturated fatty acid (MUFA) were found close to each other. The path analyses indicated that MUFA, C16:1n-7, and C18:1n-9 could be used as markers to estimate the first count, germination rate, and vigour of watermelon seeds. To the best of our knowledge, this is the first research that aimed to determine seed and seedling traits of watermelon cultivars based on the fatty acid profile

Tujuan penelitian ini untuk mengetahui filler, binder dan inokulan yang dapat digunakan sebagai bahan pelleting benih padi gogo varietas Inpago 13 Fortiz. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) diulang sebanyak tiga kali. Perlakuan terdiri dari (1) Tanpa pellet; (2) Tanah + CMC ; (3) Tanah + CMC + Mikoriza; (4) Tanah + CMC + Trichoderma; (5) Tanah + CMC + Dolomit (6) Tanah + CMC + Asam Humat ; (7) Tanah + AG; (8)Tanah + AG + Mikoriza; (9) Tanah + AG + Trichoderma; (10) Tanah + AG + Dolomit; dan (11) Tanah + AG + Asam Humat. Percobaan menggunakan tanah ultisol dengan pH (± 4,3). Perbedaan antar perlakuan diuji dengan Uji BNT pada á 5% dengan program R. Berdasarkan hasil penelitian dapat disimpulkan bahwa tanah liat yang ditambahkan dolomit atau asam humat dapat digunakan sebagai filler pelleting yang dapat dikombinasikan dengan mikroorganisme (Mikoriza dan Trichoderma) dengan Arabic Gum dan carboxymethyl cellulose (CMC) sebagai binder
