Abstract

Kedelai merupakan komoditas pangan prioritas ketiga setelah padi dan jagung dengan sumber protein nabati dan nilai gizi yang tinggi, namun dari tahun ke tahun produksinya tidak dapat mengimbangi permintaan dalam negeri, hal ini disebabkan karena berkurangnya lahan tanam serta pengaruh iklim dan cuaca. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan kedelai pada kondisi cekaman genangan, baik secara anatomi maupun morfologi. Parameter yang diamati dalam penelitian ini adalah karakter morfologi yang meliputi tinggi tanaman, luas daun, jumlah akar adventif, panjang akar, berat basah dan berat kering tanaman, serta jumlah bunga yang terbentuk. Sedangkan karakter anatomi yang diamati adalah anatomi akar, batang, dan daun tanaman Kedelai yang tercekam genangan. Penelitian morfologi diuji dengan uji ANOVA yang berlanjut pada Uji Tukey, sedangkan anatomi tanaman dilakukan dengan metode in vivo menggunakan metode parafin. Hasil penelitian menunjukan bahwa tinggi tanaman, luas daun, jumlah akar adventif, dan jumlah bunga mengalami penurunan ketika tercekam genangan, sehingga berat basah dan berat kering tanaman menurun. Pada pengamatan anatomi, akar dan batang Kedelai terdapat aerenkim (rongga udara) sedangkan bagian daun tidak. Hal ini disebabkan karena tidak ada bagian daun tanaman yang terendam air. ================================================================= Soybeans are the third priority food commodity after rice and corn with vegetable protein source and high nutritional value, but from year to year its production can not keep up with domestic demand, this is caused by the decreasing of planting land and the influence of climate and weather. This study aims to determine the response of soybean growth in conditions of inundation, either anatomically or morphologically. The parameters observed in this research are morphological character which includes plant height, leaf area, adventitous root number, root length, wet weight and dry weight of plant, and the amount of flower formed. While the anatomical character that is observed is the anatomy of roots, stems, and leaves of soybean plants that are inundated. Morphological studies were tested by ANOVA which continued on Tukey Test, while plant anatomy was done by in vivo method using paraffin method. The results showed that plant height, leaf area, adventitous root number, and the number of flowers decreased when the puddle was inundated, so that wet weight and dry weight of the plant decreased. In observation of anatomy, the roots and stems of soybean contain aerenkim (air cavity) while the leaves are not. This is because no part of the plant leaves are submerged in water.
