ii ABSTRACT
Putri Tya Sumantri. 2017. " Response of Soybean Physiology For Giving
α-tocopherol On Saline Land", supervised by Nini Rahmawati and Mariati. This research aims to determine the response of soybean physiology for to α -tocopherol in the saline field. This research was conducted on Paluh Merbau Village Percut Sei Tuan Subdistrict, Deli Serdang Regency with height of place ± 1.5 m asl, Tissue Culture Laboratory ofAgriculture Faculty,North Sumatera University, Medan with height of place ± 32 meter and Laboratory of PT. Socfin-Indonesia (SOCFINDO) Medan at altitudes of ± 32 meters above sea level in May to July 2017. This study used Factorial Random Block Design with two factors. The first factors isgenotype (grobogan x grobogan dan grobogan x anjasmoro) and dose α - tocopherol (0 ppm, 250 ppm, 500 ppm, 750 ppm). The results showed that the treatment of genotype and dose of α - tocopherol had no significant effect on the physiology of soybean F5. Descriptively, the highest mean of SOD and H2O2 enzymes were found in Grobogan x Anjasmoro genotyping
treatment and dose α - tocopherol 0 ppm (G1A0). The highest mean POD enzyme
was found in Grobogan x Grobogan genotype and dose α - tocopherol 750 ppm (G2A3). The highest mean of chlorophyll and water content is relatively in the
genotype treatment of Grobogan x Anjasmoro and dose α - tocopherol 250 ppm (G1A1).
Keywords: α - tocopherol, soybeans, saline
