Abstract
Penelitian ini merupakan penelitian eksplorasi yang dilakukan di Negeri Liang Kec. Salahutu pada bulan Maret hingga April 2017. Penelitian ini bertujuan untuk mengetahui karakteristik morfologi daun dan karakteristik anatomi stomata pada beberapa species tanaman jeruk (Citrus sp). Hasil penelitian menunjukkan bahwa, karakteristik morfologi daun pada ke-4 spesies tanaman jeruk yaitu Jeruk manis (Citrus sinensis), Jeruk nipis (Citrus aurentifolia), Jeruk purut (Citrus hystrix D.C.) dan Jeruk cui (Citrus microcarpa) memiliki perbedaan yang tampak jelas baik pada warna daun, bentuk daun, permukaan daun, tepi daun (jumlah gerigi) serta ukuran panjang dan lebar daun. Sebaliknya karakteristik anatomi stomata dan sel epidermis pada ke-4 species terutama pada permukaan daun bagian bawah (abaxial) memiliki kesamaan. Bentuk sel epidermis daun dari ke-4 spesies terdiri atas selapis sel dengan bentuk yang bervariasi antara satu sel dengan sel lainnya, demikian pula pada tipe stomatanya. Tipe stomata pada ke-4 species tanaman jeruk adalah tipe parasitik yaitu setiap sel penjaga bergabung dengan satu atau lebih sel tetangga dengan sumbu membujurnya sejajar dengan sumbu sel penjaga dan apertur. Sebaliknya kesamaan bentuk sel epidermis dan tipe stomata berbeda dengan hasil analisis kerapatan dan indeks stomata pada ke-4 spesies tanaman jeruk. Kerapatan dan indeks stomata pada ke-4 spesies tanaman jeruk berbeda nyata antar species bedasarkan hasil uji statistik. Karakteristik anataomi dari bentuk sel epidermis dan tipe stomata inilah yang kemungkinan digunakan dalam sistem taksonomi untuk mengelompokan berbagai species tanaman jeruk dalam takson yang sama.
