    Conditioning Effects on Physiological and Biochemical Characteristics of Maize Seed (Zea mays L.)
    (Badan Penelitian dan Pengembangan Pertanian, 2013) Fauziah Koes,; Ramlah Arief; Sigit Budi Santoso
    Low seed vigor causes poor seedling emergence which later on create poor plant establishment and eventually reduce yield. Various seed invigoration have been extensively carried out to improve deteriorated seed vigor due to storage. Matriconditioning is advanced method that effectively increases seed vigor. This research was conducted at Indonesian Cereals Research Institute from July to September 2010, which aimed to evaluate the effect of matriconditioning treatments on physiological and biochemical characteristics of maize seed. The treatments were arranged in Completely Randomized Design, with three kind of matrix media i.e., straw, ash and sawdust. Seeds used were freshly-harvested and 6 months-storage and each treatment used three replications. Results shows that straw matrix gave the best value on seed germination (98%) and germination speed (30,69%) of freshlyharvested seeds. Whereas, stored seed gave significant result only in seed germination (91%). Shoot-root length ratio highest value was obtained in ash matrix media (1,18 cm), which correlate with the best treatment for root length (12.62 cm). Electrical conductivity observation proved that matriconditioning using straw matrix media gave the lowest conductance, thus confirmed its ability to improved seed vigor for both new and storage seed.
