| Abstract: | Okra (Abelmoschus esculentus [L.] Moench) merupakan tanaman anggota
famili Malvaceae yang terdapat di benua Asia dan Afrika. Keanekaragaman
kultivar okra banyak dikembangkan karena merupakan jenis sayuran fungsional
dan kaya manfaat bagi kesehatan sehingga diperlukan pemahaman menyeluruh
mengenai tanaman yang akan diproduksi, terutama karakteristiknya. Penelitian ini
bertujuan menganalisis struktur anatomi daun berbagai kultivar okra yaitu Zahira
IPB, C127, Naila IPB, Clemson, dan Green Velvet. Metode yang digunakan adalah
pembuatan sediaan mikroskopis sayatan paradermal dan transversal kemudian data
dianalisis dengan One-Way ANOVA. Karakter yang diamati berupa bentuk sel
epidermis, tipe, ukuran, kerapatan dan indeks stomata, tipe trikoma, tebal kutikula,
tebal epidermis, tebal mesofil, tebal daun, dan susunan pembuluh. Hasil
pengamatan paradermal menunjukkan sel epidermis okra berbentuk irregular dan
poligonal, tipe stomata berupa anisositik, anomositik, parasitik dan hemiparasitik,
serta terdapat trikoma kelenjar dan non kelenjar. Hasil sayatan transversal
menunjukkan tebal kutikula dan epidermis tertinggi terdapat pada bagian adaksial
daun. Jaringan palisade berganda hanya ditemukan pada satu tanaman yaitu kultivar
Green Velvet. Ketebalan daun terbesar terdapat pada C127 dan terkecil terdapat
pada Green Velvet. Susunan pembuluh kelima kultivar memiliki tipe kolateral
terbuka. Kelima kultivar okra memiliki variasi dalam struktur anatomi daunnya
dengan okra merah memiliki parameter berpengaruh nyata terhadap okra hijau. Okra (Abelmoschus esculentus [L.] Moench) is a member of Malvaceae family found in Asia and Africa. The diversity of okra cultivars is widely developed due to its status as a functional vegetable with notable health benefits. Therefore, a comprehensive understanding of the plants to be cultivated, especially their characteristics, is essential. This study aimed to analyze the leaf anatomical structures of okra cultivars, namely Zahira IPB, C127, Naila IPB, Clemson, and Green Velvet. The method involved preparation of microscopic slides paradermal and transversel sections, followed by observation and analysis using One-Way ANOVA. The anatomical traits observed included epidermal cell shape, stomata type, density, index, trichome type, cuticule thickness, epidermal thickness, mesophyll structure, and vascular bundle arrangement. Paradermal observations showed okra epidermal cell shape was irregular and polygonal. The type of stomata identified were anisocytic, anomocytic, parasitic, and hemiparasitic. Both glandular and non-glandular trichomes were present. Transverse section showed that the greatest cuticule and epidermal thickest was observed Green Velvet. The thickest leaf was found in C127 and the thinnest in Green Velvet. All cultivars exhibited an open collateral arrangement. The five cultivars show variation in leaf anatomical structure, with red okra exhibiting significantly different parameters compared to green okra. |
