Pengaruh Salinitas (NaCl) terhadap Pertumbuhan Bayam Ageng (Amaranthus Paniculaus L.). (Influence of Salinity (NaCl)to Plant Grwth of Bayam Ageng (Amaranthus Paniculatus L.).

ABSTRAK Influence of salinity (NaCI) to plant growth of Amaranthus paniculatus L. was studied. Treatments were carriied out on NaCI solution with concentrations of 0 (control), 500, 1000, 1500 and 3000 ppm. The treatments of 500, 1000 and 1500 ppm. increased plant height, leaves number per plant and dry weight per plant significantly. By treatment of 3000 ppm., number of mortality plants increased significantly. There was no difference of flowering times, even by treatment of 3000 ppm, Mechanism of their metabolism was discussed. Abstrak Pengaruh salinitas (NaC1) terhadap pertumbuhan tanaman bayam ageng (Amaranthus paniculatus L.) dipelajari. Perlakuannya dengan menggunakan kadar NaCI : 0 (kontrol), 500, 1000, 1500 dan 3000 ppm. Perlakuan dengan menggunakan kadar 500, 1000 dan 1500 ppm. meningkatkan tinggi tanaman, jumlah daun/tanaman dan beret kering/tanaman dengan nyata sekali. Dengan perlakuan 3000 ppm., jumlah kematian tanaman meningkat nyata sekali. Tidak tampak pengaruhnya terhadap waktu berbunga, walaupun dengan perlakuan 3000 ppm. Mekanisme metabolismenya dibahas
