Abstract

Pengetahuan ekofisologi eboni penting dalam penerapan sistem silvikultur hutan alam karena setiap jenis mempunyai reaksi yang berbeda terhadap faktor lingkungan yang berbeda dan pada tahap yang berbeda pula.Penelitian ekofisiologi juga berperan dalam pengelolaan dan pelestarian eboni.Informasi tentang penyesuaian antara faktor fisiologi dan faktor lingkungan yang berpengaruh terhadap metoda pemeliharaan permudaan eboni yang tepat, baik di hutan alam maupun pada hutan tanaman dibahas dalam tulisan ini.Hasil akhir dari pemantapan metode ini dapat dijadikan bahan kajian lebih mendalam untuk menyusun pedoman teknis pemeliharaan permudaan alam eboni baik secara ex-situ maupun in-situ.Berdasar pada penelitian yang berhubungan dengan faktor lingkungan tumbuh eboni yang telah dilakukan, disarankan beberapa prioritas penelitian ekofisiologi.

Abstract

This paper describes the ebony (Diospyros celebica Bakh.)site characteristics in Amaro Forest,Barru District, South Sulawesi including its secondary succession to create a favourable conditions for stand establishment. Association analysis shows that a wide variety of lowland species have been identified grows together with the ebony.Physical characteristics rather than chemical fertility of soils show a great value in supporting ebony stand growth.Poor stand with low natural regeneration of these remaining fragmented forests suggest the need to apply enrichment planting and improvement cutting to increase their productivity.

Abstract

Research on the analysis of the anatomy of the stomatal and trichomes of the medicinal plant Dandang Gendis Clinacanthus nutans (Burm.f.) Lindau in Makassar City. This study aims to determine the anatomical structure of the stomatal and trichomes of longitudinal cross-section of leaves that are used as herbal medicines. This research method was used to spread acetone to obtain stomatal prints on the leaf surface, the data were analyzed descriptively. The results of the analysis of the anatomy of the stomatal and trichomes of leaves of the medicinal plant Dandang Gendis Clinacanthus nutans (Burm.f.) Lindau was a diacytic type of stomatal, the spread of stomatal was only found on the surface of the abaxial leaf including the apple type. The number of abaxial stomatal was 160 stomatal/mm2. The number of epidermal cells was 748 epidermis/mm2 and abaxial 504 epidermis/mm2, stomatal index 23.95%, and stomatal size 159.26 ┬Ám. On the adaxial and abaxial surfaces of the leaves of Dandang Gendis Clinacanthus nutans (Burm.f.) Lindau, glandular and lithocyst trichomes were encountered.
