Abstract

Coleus scutellarioides is Labiatae. It have much varieties based on the leave shapes and colors. In the identification is not enough based on morpho-logical organ characters, but it can also based on the pollen morphology. The purpose of this study to determine the pollen morphology of seven varieties of Coleus scutellarioides. The research was conducted in the laboratory of Botany Department of Biology, State University of Padang, in April-May 2012. Seven varieties of Coleus used came from Padang Panjang and Lintau Buo. Pollen taken from bloomed flowers and it made be slides used acetolisis methods and 1% safranin staining method. Data were analyzed descriptively included pollen unit, polarity, symmetrically, size, shape, aperture, and the shape of pollen surface. The seven Coleus pollen varieties have similirity of the type of monad pollen unit, polarity isopolar type, radial symmetry, type colpate with 6 aperture located in the equatorial (Stephano), and reticulate surface-shaped pollen. Prolate spheroid shapes found in var. Eleanor, subprolate forms in var. Batique Fetish, var. Fack, var. Apricot, var. Burgundy Giant, var. Eleanor, and var. Flambe. Whereas prolate shapes found in var. Batique Fetish, var. Fack, and var. Va Va Boom. Pollen morphology of seven varieties of Coleus scutellarioides have different shape and the author have found 3 shape of pollen as the prolate spheroidal, subprolate and prolate.Key words: pollen, Coleus scutellarioides, identification

Abstract

Pollen is the male genitalia of plants. The pollen morphology can vary within a species and between species, so that it can be used as an identification tool. It also has contribution to other disciplines such as Paleobotany, Paleoecology, Palynology, Aeropalinologi, Medical and determination of  honey quality. This study aims to reveal the pollen morphology of some species of Solanum. The Solanum which was studied were Solanum melongena var. serpentinum (purple and white fruit), Solanum melongena var. esculentum (purple and green fruit), Solanum tuberosum, Solanum torvum and Solanum ferox. The design of research is a descriptive study. The method used was asetolisis with 1% safranin staining in 70% alcohol. The characters pollen morphology observed were: units, polarity, symmetry, size, shape, or form surface ornamentation, number and type of aperture. The results showed the unit of single pollen (monads), with isopolar polarity, radial symmetry and size medium. The length of polar axis (P) ranged from 20 to 32.5, while the length of the equatorial diameter (E) ranged from 20 to 37.7, so the form of Solanum pollen can be classified into classes; Oblate, Suboblate and Oblate spheroidal. Aperture found was 3-4 aperture with the aperture found pore located at the equatorial type. In conclusion, several species of Solanum pollen have similarity in terms of units, polarity, symmetry, size and difference in terms of form and quantity of aperture.Key words: pollen, solanum, identification

Abstract

Background and objective.The response of rice plants to drought stress was preceded by physiological response in the form of reduction of transpiration rate to reduce water loss by closing stomata, reducing stomata, and decreasing leaf surface area by leaf rolling. Therefore, it is necessary to research the morphological character and physiological character of plants such as leaf area analysis and stomata index to find out their response to drought stress and without drought. Based on this, this research is aimed to know the area and index of stemata leaves of rice plants (Oryza sativa L.) varieties of Cisokan and Batang Piaman due to drought stress.Methodology. Drought treatment was performed by withholding water for 12 days in greenhouse.Data were taken destructively on days 0, 4, 6 and 12 after treatment. Result. Drought stress had an effect on decreasing leaf area and stomata index on both varieties. The lowest leaf area is found in Cisokan variety. Likewise with the stomata index, the lowest yield after 12 days of treatment was found in the Cisokan variety. Low leaf area and stomatal index are known to be more resistant to drought because they can reduce the rate of transpiration in plants. Keywords:    Drouhgt stress, Leaf Area, Stomata index

Abstract

Jamur Fusarium oxysporum merupakan jamur patogen umumnya ditemukan pada tanaman holtikultura. Jamur ini menyebabkan penyakit layu fusarium. Fungisida sintetis merupakan pilihan yang sering digunakan petani untuk menghambat penyebaran jamur ini. Namun penggunaannya menimbulkan banyak dampak negatif bagi lingkungan. Trichoderma harzianum memiliki sifat antagonis yang dapat menggantikan fungisida sintetis dalam menghambat pertumbuhan F. oxysporum. T. harzianum membutuhkan media pembawa seperti beras. Namun membutuhkan biaya yang cukup tinggi dan bersaing dengan kebutuhan manusia. Untuk itu dilakukan campuran antara beras dan ampas tebu untuk mencari media alternatif. Tujuannya agar mendapatkan media tumbuh yang lebih efektif dan efisien.Penelitian ini menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 3 ulangan. Perlakuanya terdiri dari A. Media beras 100%, B. Media ampas tebu 100%, C. Media beras dan ampas tebu (1:1), D. Media beras dan ampas tebu (2:1), dan E. Media beras dan ampas tebu (1:2). Paremeter yang diamati yaitu pertumbuhan T. harzianum, kepadatan konidia, dan persentase hambatan terhadap  F. oxysporum.Hasil penelitian ini menunjukkan bahwa T. harzianum dapat tumbuh pada campuran media beras dengan ampas tebu. Media tumbuh mempengaruhi pertumbuhan, kepadatan konidia, serta daya hambatnya terhadap F. oxysporum Pertumbuhan yang terbaik yaitu pada media ampas tebu 100 %, kepadatan konidia tertinggi pada media beras 100% (11,6 x 109/ mL) dan persentase daya hambat tertinggi pada media ampas tebu 100% (60%). Hal ini menunjukkan bahwa media alternatif terbaik yaitu media ampas tebu 100%. Keywork : Fusarium oxysporum, layu fusarium, media, Trichoderma harzianum

Abstract

People in Pasar Terandam Village still use plants as food additives. However, research has never been carried out, so that it has not been recorded and has not been listed. If not inventoried and cultivated, the plant can be lost or extinct. This study aims to determine the plants, -plant organs, plant status, and how to use them as traditional food additives in buffalo meat curry in Pasar Terandam Village, Barus District, Central Tapanuli Regency. This research was conducted from April to May 2020 using a survey method through observation and interviews. The results showed that 19 species from 15 families were used by the community of Pasar Terandam Village as traditional food additives to buffalo meat curry. Parts of plant organs used are tubers, leaves, stems, seeds, fruits, skins, and rhizomes. These plants is processed by cooking, pulverizing / mashed, pounded, cut, shredded, roasted and boiled. The community obtains these plants by cultivating seven species around the house or in the garden and buying them in markets or stalls for 12 species.Masyarakat di Desa Pasar Terandam masih banyak menggunakan tumbuhan sebagai bahan tambahan pangan. Namun, belum pernah dilakukan penelitian sehingga belum terdata dan belum terinventaris. Kalau tidak diinventaris dan dibudidayakan maka tumbuhan itu bisa hilang atau punah. Penelitian ini bertujuan untuk mengetahui jenis-jenis tumbuhan yang digunakan, bagian organ tumbuhan, status tumbuhan dan cara pemanfaatannyasebagai bahan tambahan pangan tradisional pada gulai kerbau di Desa Pasar Terandam Kecamatan Barus Kabupaten Tapanuli Tengah. Penelitian ini dilakukan pada bulan April sampai Mei 2020 menggunakan metode survei melalui observasi dan wawancara.Hasil penelitian didapatkan 19 species dari 15 familia yang digunakan masyarakat Desa Pasar Terandam sebagai tambahan pangan tradsional pada gulai kerbau. Bagian organ tumbuhan yang digunakan adalah umbi, daun, batang, biji, buah, kulit, dan rimpang. Cara penggunaanya yaitu dengan dimasak, diuleg/dihaluskan, ditumbuk, dipotong, diparut, disangrai dan direbus.Masyarakat memperoleh tumbuhan tersebut dengan cara membudidayakan di sekitar rumah atau di kebun sebanyak 7 specises dan membelinya di pasar atau warung sebanyak 12 species.
