Description:

Lumpur lapindo mengandung Natrium (Na) dan Clorida (Cl) yang sangat tinggi yaitu 1,92%, sehingga memiliki salinitas yang tinggi.Penelitian ini bertujuan untuk mengetahui morfologi dan anatomi akar kacang hijau (Vigna radiata) pada media tanam campuran tanah dan lumpur lapindo. Dalam penelitian ini konsentrasi lumpur lapindo yang digunakan sebagai campuran adalah 0% (kontrol), 10%, 20%, 30%, 40%, 50%, 60% dan 70%. Pengamatan yang dilakukan meliputi morfologi (tinggi tanaman, panjang akar menggunakan penggaris dan jumlah bulu akar diamati menggunakan mikroskop stereo (Olympus, SZ 51, Japan)). Pengamatan anatomi (tebal sel epidermis, korteks, endodermis dan diameter stele) menggunakan fitomikroskop (Olympus, BX 41, Japan) dengan dibuat irisan preparat dan pewarnaan safranin. Analisis data dalam penelitian ini menggunakan ANOVA yang dilanjutkan dengan uji Dunnet dengan taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa penambahan tingkat konsentrasi lumpur lapindo dalam media tanam mengakibatkan tinggi tanaman dan panjang akar lebih pendek dan jumlah bulu akar lebih sedikit, begitu pula pengamatan anatomi berukuran lebih kecil dibandingkan dengan tanaman kontrol.

Alt. Description

Lapindo mud contain high concentration of Natrium (Na) and Chloride (Cl), therefore having high salinity. The purpose of this study is to know morphological and anatomical structure of bean’s (Vigna radiata) roots in the medium of soil and Lapindo mud mixture. Lapindo mud that used as a mixture were 0% (control), 10%, 20%, 30%, 40%, 50%, 60%, and 70%. Plant morphology observed include plant height and roots length by ruler and stereo microscope (Olympus SZ 51, Japan) to observe the number of root’s hair, while the anatomy include the epiderm thickness, cortex thickness, endoderm thickness, and stele diameter observed by photomicroscope (Olympus BX 41, Japan), prepared previously by making a section and stained with safranine. Data analyzed by ANOVA then continued by Dunnet test at level 95%. The result showed that increasing of Lapindo mud concentration level in soil medium result in shorter plant height and roots length, and fewer root’s hair while compared to the control plants. On anatomical was smaller than control plants.
