Abstract

KONSENTRASI KLOROFIL DAUN SEBAGAI INDIKATOR KEKURANGAN AIR PADA TANAMAN Nio Song Ai1) dan Yunia Banyo1) 1)Program Studi Biologi FMIPA Universitas SamRatulangi Manado, 95115;email: nio_ai@yahoo.com ABSTRAK Kekurangan air mempengaruhi semua aspek pertumbuhan tanaman, yang meliputi proses fisiologi, biokimia, anatomi dan morfologi. Salah satu respons fisiologis tanaman terhadap kekurangan air adalah penurunan konsentrasi klorofil daun yang dapat disebabkan oleh pembentukan klorofil dihambat, penurunan enzim rubisco, dan terhambatnya penyerapan unsur hara, terutama nitrogen dan magnesium yang berperan penting dalam sintesis klorofil. Kandungan klorofil daun dapat dipakai sebagai indikator yang terpercaya untuk mengevaluasi ketidakseimbangan metabolisme antara fotosintesis dan hasil produksi pada saat kekurangan air. Kata kunci: cekaman, fotosintesis, respons fisiologi     THE CONCENTRATION OF LEAF CHLOROPHYLL AS WATER-DEFICIT INDICATOR IN PLANTS ABSTRACT Water deficit influences all aspects of plant growth including physiological, biochemical, anatomical and morphological processes. One of plant physiological responses to water deficit is the decrease of leaf-chlorophyll concentration because the chlorophyll synthesis is inhibited, the rubisco enzyme was reduced and the absorption of nutrients, especially nitrogen and magnesium that are required for chlorophyll synthesis, was inhibited. The concentration of leaf chlorophyll is able to be used as reliable indicator for evaluating unbalanced metabolism between photosynthesis and plant production under water deficit. Keywords: stress, photosynthesis, physiological response

Abstract

EVOLUSI FOTOSINTESIS PADA TUMBUHANABSTRAK Fotosintesis adalah proses sintesis karbohidrat dari bahan-bahan anorganik (CO2 dan H2O) pada tumbuhan berpigmen dengan bantuan energi cahaya matahari. Fotosintesis terdiri atas 2 fase, yaitu fase I yang berlangsung pada grana dan menghasilkan  ATP dan NADPH2 serta fase II yang berlangsung pada stroma dan menghasilkan karbohidrat. Molekul air tidak dipecah dalam fotosintesis primitif dan setelah evolusi molekul air dipecahkan melalui 2 fotosistem sehingga O2 dilepaskan ke atmosfir. Fotosintesis berkembang menjadi lebih kompleks secara biokimia sampai terjadinya pemisahan antara respirasi dan fotosintesis beserta regulasinya. Evolusi tipe-tipe fotosintesis seperti C4 dan CAM merupakan akibat menurunnya rasio CO2/O2 dan radiasi yang intensif pada atmosfir. Kata kunci: C3, C4, CAM   THE EVOLUTION OF PHOTOSYNTHESIS IN PLANT ABSTRACT Photosynthesis is the synthesis process of carbohydrate from inorganic materials (CO2 dan H2O) in plants with pigments using light energy. There are 2 phases of photosynthesis, i.e. phase I that occurs in grana and results in ATP dan NADPH2 and phase II that occurs in stroma and results in carbohydrate. The water molecule was not split apart  in the primitive photosynthesis and after evolution the water molecule was oxidized via 2 photosystems, so that O2 was released to the atmosphere. Photosynthesis developed biochemically to be more complex until photosynthesis and its regulation was separated from respiration. The evolution of photosynthesis types, such as C4 and CAM, was resulted from the decrease of ratio CO2/O2 and the intensive radiation in the atmosphere. Keywords: C3, C4, CAM
