“…is catalyzed by LIPG to form fatty acids and glycerin; thereafter, fatty acids and glycerin are converted to sucrose via glycolysis, tricarboxylic acid cycle, or glyoxylate cycle, thereby providing nutrients for seed germination (Kaymak, 2014;Basnet et al, 2016). We confirmed that HDT significantly suppressed LIPG, ACX, and INV activities along with their associated gene expression in 12-month-stored sunflower seeds during the early germination stage.…”

Sunflower seed storage is accompanied by the loss of seed vigor. Seed drying is a key link between seed harvest and seed storage; however, to date, the effect of seed drying on sunflower seed deterioration during storage remains unclear. The present study performed hot air drying for sunflower seeds with an initial moisture content of 30% to examine the manner in which drying temperature (35, 40, 45, 50, and 55°C) affects the drying performance and seed vigor following storage process (6 and 12 months). A drying temperature of 40°C was evidently safe for sunflower seeds, whereas the high drying temperatures (HTD, 45, 50, and 55°C) significantly lowered sunflower seed vigor by regulating the fatty acid metabolism, glycometabolism, and abscisic acid (ABA)/gibberellin (GA) balance. HDT significantly increased the seed damage rate and accelerated sunflower seed deterioration during natural and artificial aging process. Further biochemical analysis indicated that HDT significantly increased lipoxygenase and dioxygenase activities, leading to malonaldehyde and reactive oxygen species over-accumulation during storage. During early seed germination, HDT significantly inhibited fatty acid hydrolysis and glycometabolism by decreasing triacylglycerol lipase, CoA-SH oxidase, and invertase activities. Moreover, HDT remarkably increased ABA levels but reduced GA levels by regulating gene expressions and metabolic enzyme activities during early imbibitions. Cumulatively, the seed drying effect on sunflower seed vigor deterioration during the storage process may be strongly related to fatty acid oxidation and hydrolysis metabolism, toxic substance accumulation, and ABA/GA balance.

“…The pre-test with two temperatures showed that the highest seed germination percentage was achieved at 24°C and 28°C, because the pepper species seeds germinate well in a constant temperature range between 15°C and 30°C (Kaymak, 2014); however the highest germination rate of pepperoncini was …”

Biochar is a solid material obtained from the carbonization of biomass. The effect of biochar on the germination and seedling growth of pepperoncini pepper (Capsicum annuum L. cv. Stavros) was studied under controlled growth chamber conditions in two experiments. The substrates in the pre-test experiment (first experiment) were 2%, 4%, 6%, 8%, and 10% biochar (at 24°C or 28°C), while in the second experiment they were acidic (pH 6.1) or alkaline soil (pH 7.2), with or without biochar at 24°C. Three replicates (Petri dishes) for each treatment were placed at random in a growth chamber for 12 days at a 16/8h light/dark photoperiod, 12 klx light intensity and 80% relative humidity. In biochar substrates the seed germination percentage in Η 2 Ο-control was high at 24°C and low at 28°C. At 28°C it was also increased (4°C) and it was higher than the corresponding one in the Η 2 Ο-control. At both temperatures (24°C and 28°C) there was a tendency for increased height growth. The percentage of seed germination in acidic soil substrates was low (42%), while in alkaline soil substrates high (82%). All biochar applications in acidic soil substrates increased the seed germination percentage, which varied between 53% and 67%. Biochar application in alkaline soils substrates did not influence seed germination. Seedling height in acidic soil substrates was 0.15cm, while in alkaline soil substrates it was 1.63cm. Biochar application in acidic soils increased the seedling height, while in alkaline soils it was reduced when compared to the control.

“…Specifically, limited information is available on the relationship between seed traits and fatty acids. In previous reports, the authors found that both seed germination and vigour are two vital seed traits that could be influenced by colour of seed and fatty acid content (Dogras et al 1977;Kaymak, 2012;Kaymak, 2014a;Kaymak, 2014b, Kaymak, 2015. The fatty acid content of the seed has been related to germination and seed vigour in different crops.…”

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
