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 αtocopherol 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. SocfinIndonesia (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
