Abstract

Yardlong beans (Vigna unguiculata subsp. sesquipedalis (L.) Verdc.) is a vegetable source of vitamins and minerals which are quite widely cultivated in Indonesia. Phenology study the phases that occur in a plant that is provides benefits in agriculture, but information on the phenology of legumes crops in Indonesia is still scarce. This study aims to observe the reproductive phenology and pollen production of the yardlong bean cultivar Sabrina. A phenological study was carried on 7 plants to obtain information on the timing and duration of the reproductive period, inflorescence and fruiting phases, peak flowering time, and flower biology. Pollen production was observed in 5 samples of flowers. Pollen microscopic preparations were made using the acetolysis method. The results showed that the flowering and fruiting phases took 21-29 days; including flower initiation phase 7-10 days, small bud phase 1day, large bud phase 1 day, anthesis phase 1-2 days, and fruit development phase 11-15 days. Flower initiation occurred 36 days after planting (DAP), and flower blooming occurred 49 DAP. The peak of flowering occurred at 56-62 DAP. The flowers of the Sabrina cultivar have purplish-white corollas, producing about 276±23.58 pollen/anther.

Abstract

The diversity of forage plant species for elephants can be analyzed by observing the anatomy of undigested plant fragments in the fecal. This study aims to identify forage plants from the fecal samples of Sumatran elephant in Way Kambas National Park. The research methods include collected fecal samples at Way Kambas National Park, prepared slide microscope of epidermis of the plant fragments using the whole mount method, observed the anatomical characters and identified the plant fragments based on data from previous studies and reference. The results obtained 34 types of epidermis which were differentiated based on the characteristics of epidermal cell, stomata and trichomes. These epidermis types were used to identify the plants forage by Sumatran elephants. We found leaf fragment of four families, namely Arecaceae, Cyperaceae, Poaceae and Zingiberaceae. The most common fragments found in the fecal samples were the leaf fragments of Poaceae (28 type epidermis). Anatomical study on the plant fragments in fecal can be used as an alternative method in studying plants consumed by elephant.

Abstract

Physalis angulata merupakan suku Solanaceae yang dapat digunakan sebagai tumbuhan obat. Penelitian ini bertujuan untuk mengidentifikasi struktur sekretori daun dan batang P. angulata. Studi histologi struktur sekretori daun dan batang P. angulata telah dilakukan. P. angulata memiliki struktur sekretori berupa trikoma. Trikoma tersebut merupakan trikoma kelenjar kapitat multiselular yang terdiri atas sel tangkai dan sel kepala. Trikoma tersebut tersebar pada bagian epidermis daun dan batang. Ukuran sel kepala dan tangkai trikoma bervariasi. Kerapatan trikoma tertinggi ditemukan pada epidermis batang.
