Karakterisasi stomata daun pada tanaman hias familia Araceae

Introduction

Karakterisasi stomata daun pada tanaman hias familia araceae. Penelitian ini mengkarakterisasi stomata daun pada 17 spesies tanaman hias familia Araceae, menganalisis lokasi, tipe, bentuk sel penutup, sel tetangga, dan ukurannya.

Abstract

Familia Araceae banyak dimanfaatkan sebagai tanaman hias, karena memiliki bentuk dan corak daun yang bervariasi. Di Indonesia terdapat 25% marga Araceae dari keseluruhan marga Araceae di dunia. Tujuan dari penelitian ini yaitu menganalisis karakter stomata daun pada tanaman hias familia Araceae di Kelurahan Ngaliyan. Pengamatan karakter stomata menggunakan metode replika. Hasil penelitian menunjukkan bahwa ditemukan 17 spesies dari 10 genus familia Araceae. Pada spesies Homalomena cordata, Aglaonema simplex, Anthurium hookeri, Phlodendron billietiae, Amorphophallus variabilis, dan Monstera dubia stomata hanya ditemukan di permukaan bawah dan tipe penyebaran apel. Sedangkan spesies lainnya stomata ditemukan di permukaan bawah dan atas serta tipe penyebaran potato. Seluruh spesies memiliki bentuk sel penutup tipe halter. A. hookeri, P. billietiae, dan C. bicolor red rhapsody memiliki 4 sel tetangga, sedangkan 14 sel lainnya 2 sel tetangga. Ukuran stomata berbeda pada setiap spesies yang diamati. Ditemukan 3 tipe stomata yaitu tipe anomositik, tipe tetrasitik, dan tipe parasitik.

Review

This study, "Karakterisasi stomata daun pada tanaman hias familia Araceae," addresses a relevant and interesting topic by focusing on the stomatal characteristics of ornamental plants within the Araceae family, which are highly valued for their diverse foliage. The stated objective to analyze leaf stomatal characters in Araceae species found in Kelurahan Ngaliyan is clearly met. The research successfully identified 17 species from 10 genera, providing a solid foundation for the subsequent detailed analysis. Key findings include variations in stomatal distribution – with some species showing stomata only on the abaxial surface while others exhibit them on both surfaces – and the consistent observation of halter-type guard cells across all studied species. Furthermore, the abstract reports distinct differences in the number of subsidiary cells and stomatal size among species, culminating in the identification of three primary stomatal types: anomocytic, tetracytic, and paracytic. Methodologically, the use of the replica method is appropriate for stomatal observation and yields reliable data. A strength of this work lies in the comprehensive coverage of 17 species, which allows for comparative analysis within the Araceae family. The findings regarding stomatal distribution, specifically the distinction between species with hypostomatic leaves and those with amphistomatic leaves, are valuable for understanding leaf physiology and potential ecological adaptations. The consistent finding of halter-type guard cells is noteworthy and could serve as a useful diagnostic character or point of comparison for future studies. While the identification of anomocytic, tetracytic, and paracytic stomata types aligns with standard botanical classifications, the abstract's mention of "tipe penyebaran apel" and "tipe penyebaran potato" requires further elucidation. These terms are non-standard in international botanical literature and would benefit from clarification to standard English equivalents or a detailed explanation of what these 'distribution types' entail, especially if they refer to patterns beyond simple density or adaxial/abaxial presence. Overall, this research makes a significant contribution to the botanical understanding of ornamental Araceae species in Indonesia. The detailed characterization of stomata provides valuable morphological data that could be instrumental for taxonomic differentiation, horticultural practices, and potentially in exploring the ecological adaptations of these plants. Future studies could expand upon these findings by correlating stomatal characteristics with environmental parameters such as humidity or light intensity, or by investigating the physiological implications of the observed stomatal types and distributions. This study forms a strong foundation for further research into the diverse Araceae family, and the findings are relevant for botanists, horticulturists, and plant enthusiasts interested in this economically important plant group.
