【 摘 要 】

The study aimed to evaluate the anatomical characteristics of six sweet potato varieties (Ipomoea batatas L.) after induction of organic fertilizer. Research used Completely Randomized Block Design with 3 replications. Five sweet potato varieties (J) were used i,e: Antin 3 (J1), Jago (J2), Cilembu (J3), Shi Royutaka (J4), Local Purple (J5) and Local White (J6). Petroganic Organic Fertilizers were applied 20 tons/ha, three weeks before sweet potato cuttings were planted. Observation of anatomical characteristics include: stomata density, length and width opened stomatal pores, mesophyll thickness, diameter of the petiole cortex. All characteristics were observed 60 days after planting (HST) using a microscope with a camera Optilab 2.2 and image capture with the Image Raster 3.0 program. Anatomical characters of sweet potatoes showed stomata density J1, J2, J3, J4, J5 and J6 respectively 8.56; 6.11; 5.11; 6.33; 8.56 and 9.11 in 75796.36 μm. The length of opened stomata pores were 26.99 μm, 32.08 μm, 28.96 μm, 38.72 μm, 39.52 μm and 35.86 μm. The width of opened stomata pores were 7.95 μm, 5.11 μm, 4.67 μm, 5.04 μm, 9.28 μm and 6.98 μm. The mesophyll thickness were 364,986 μm, 280,703 μm, 389,743 μm, 245,749 μm, 261,439 μm and 434,913 μm. The diameter of the petiole cortex were 454,030 μm, 373,453 μm, 456,439 μm, 373,001 μm, 275,647 μm and 318,785 μm. Five sweet potato varieties differ in anatomical characters.
