The aim of study was to investigate the effects of boron on germination and seedling parameters of sorghum [Sorghum bicolor (L.) Moench] under drought stress conditions. The experiment was conducted in a factorial trial in a randomized plot design with four replication in a growth chamber. In this study, three different sorghum cultivars were used. Drought conditions were performed at three different levels using PEG (0.-0.4 MPa and -0.8 MPa). Four boron doses (0-5-10-15 mM B) solutions are formed as boric acid (H3BO3). Parameters measured in Gözde 80 were superior to other cultivars under drought stress conditions. The maximum mean germination time, seedling viability index, shoot and root length, shoot and root fresh weight, and total biomass, were detected as 4 days, 74%, 10 cm, 13 cm, 63 mg, 21 mg, and 80 mg, respectively. Differences were noted in the response of different sorghum cultivars to drought stress, and significant decreases were observed as the drought level increased. Low boron applications generally increased germination and seedling parameters compared to control under drought conditions. The boron effects applied to alleviate the drought stress effects have been noticeably positive. Compared to control conditions, the best results were also generally observed in the application of 5 mM B at a drought stress dose of -0.4 MPa. It was concluded that high doses of boron applications caused double stress with drought and were even lower than drought applications alone. It was recorded that due to the reasons listed above, careful attention should be paid to the boron doses to be applied.

Lathyrus sativus L. (grass pea) is an annual legume crop commonly cultivated in marginal areas and used as human food and animal feed for many years. Also, grass pea seeds might be a sufficient source of various crucial nutrients for both human and animal nutrition, especially during times of famine. This study was conducted to characterize 15 superior grass pea genotypes grown two locations (Antalya and Isparta) with respect to fatty acids, oil content and oil yield. The linoleic acid was the dominant fatty acid present in all grass pea genotypes, with its contents ranging from 39.38% (GP213) to 42.61% (GP150). Lauric acid, tridecanoic acid, pentadecanoic acid, palmitic acid and erucic acid were found at trace levels, meanwhile oleic acid was determined as the second excess fatty acid in all genotypes, ranging from 19.12 to 21.41%. The amounts of saturated (SFA), monounsaturated (MUFA), and polyunsaturated (PUFA) fatty acids were calculated to be between 23.82-28.57%, 19.63-22.36%, and 51.06-54.43%, respectively. The oil ratios and oil yields of the genotypes varied between 0.59 and 0.80% and between 0.90 and 23.91 g plant-1, respectively. The significance t-test for mean values indicated that there weren’t significant differences between the locations for all fatty acid features and oil content except for the oil yields (p=0.001). These presented data can be used as selection criteria in further breeding studies to develop new grass pea cultivars.

The aim of this research is investigating the effects of boron on the germination and growth of three sorghum cultivars at different salinity stress levels. The experiment was arranged as four replications according to the factorial experimental design in completely random blocks The three sorghum (Sorghum bicolor L.) cultivars (Erdurmuş, Uzun and Gözde 80) selected for the genetic material. NaCl compound was utilized as salt source and solutions were prepared at concentrations of 0-75 mM-150 mM. Boron was applied as H3BO3 at 0-5-10-15 mM. In general regarding growth parameters, the values obtained in Gözde 80 cultivar were determined as the highest averages. Whereas the salinity levels effect was examined in this study, a decrease was determined in the parameters measured as the level of the stress factor increased. Salinity had a high adverse effect at the 150 mM level, and as expected the highest averages were obtained in the control treatments. Low-dose boron applications have possitive effects on germination and growth parameters in this experiment. Therewithal under salinity stress conditions, low-dose boron applications showed affirmative efficacy compared to the control of each condition. In this experiment, determined that boron applications reduce this effect under salinity stress conditions that sorghum seeds may encounter during the germination period, but the boron dose level to be applied should be properly controlled.

The aim of study was to investigate the effects of salicylic acid on germination and seedling parameters of maize cultivars (Zea mays L.) under drought stress conditions. The research was carried out in a growth chamber in a factorial experiment design with four replications in random plots. In this study, three different silage maize cultivars were used (Side, Pehlivan and Burak). Drought conditions were established using Polyethylene glycol-6000 (PEG-6000) at three different levels (0.-0.4 MPa and -0.8 MPa). Salicylic acid applications were calculated at three different doses of 0-0.1-0.2 mM. The parameters examined in Side cultivar gave superior results exposed to drought conditions compared to other cultivars. Differences were determined in the response of maize cultivars to drought stress, and statistically noteworthy diminishes were also observed as the drought level enhanced. It was displayed that salicylic acid applications generally boosted germination and seedling parameters exposed to drought conditions compared to control. The maximum shoot lenght was detected at 0.2 mM SA dose with 2.30 cm but that did not exhibit significant numerical differences. SA applications, on the other hand, did not have an effect on root length. Moreover, the best result of shoot fresh weight was recorded in 0.1 mM SA application, as root fresh weight gave the best in 0.2 mM SA application. Furthermore, when a correlation is made between the specified parameters, the highest relation was markedly positive and linked between GR and GI (r: 0.99, p
