Abstract

ABSTRACTTomatoes (Lycopersicum esculentum Mill.) horticultural which are very good for consumption as well as industrial materials.  However, the cultivation of tomatoes still faces many obstacles, one of them is the seed.  The quality of old seeds decreases with age of seeds, so that it will affect a crop production.  This study aims to determine whether the magnetic field strength can improve tomato plant vigor.  The study was conducted using a completely randomized design (CRD) of one factor, the induction of a magnetic field consisting of 3 levels, namely 0.1 mT (M0.1), 0.2 mT (M0.2), 0.3 mT (M0,3) for 7 minutes 48 seconds. This study uses two controls;  positive control the new seed (Sn) and negative control was the old seed (So) from not being given a magnetic field treatment each experiment unit is repeated 5 times.  The parameters measured were plant height, chlorophyll content, and carbohydrate content.  The data obtained were analyzed.  If there was a difference between treatments, it was continued with the smallest difference between treatments using the Tukey's test at the 5% level.  The results of the analysis prove that the magnetic field induction of the old seed can increase seed vigor, causing plant height, chlorophyll and carbohydrate content to be the same as plants from new seeds.    Keywords: tomatoes, old seeds, strong magnetic field

Abstract

Colletotrichum is known  causing anthracnose diseases on many plants. The taxonomy of Collettorichum spp. have been largely concerned with classical descriptive criteria such as conidial shape and size, and presence, absence and morphology of setae.The samples of Colletotrichum were collected from infected pepper fruits from the traditional market in Lampung. The samples observed under microscope and identification of Colletotrichum using standart texts. Two species were found; 1. Colletotrichum gloeosporioides (Penz.) Sacc. with four different conidial shapes,cylindrical with obtuse ends, cylindrical with a slightly tapered base and obtuse apex, slightly clavate, and cylindrical with obtuse ends with narrowing in the centre ; 2. Colletotrichum capsici (Syd.) Butler & Bisby with conidia falcate, fusiform, apices acute.Keyword : Anthracnose, Colletotrichum, Pepper

Abstract

Indonesia is one of the countries with high Araceae diversity, which is about  36 genera consisting of 669 species. However research on the characteristics of Araceae in Indonesia is still limited. The existence of Araceae in Liwa Botanical Garden has not been studied. One of the characteristics in assessing plant diversity is anatomical features. Therefore, the aim of this study is to determine the anatomical characteristics of Araceae in Liwa Botanical Garden. This research was conducted from October to November 2019 in Liwa Botanical Garden, West Lampung, Lampung using the cruise method (Cruise Method). Araceae plants that are found identified in the Botany Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung. The anatomical features of the leaves and petioles of Araceae was studied carefully. The results of this study indicate that each type of Araceae plant has different characteristics of epidermal cell structure and stomata. The characteristic shape of the epidermal cells is upright, while the characteristic shape of the stomata is amphibrachyparacitic. A certain types of Araceaeshows s a special characteristic which is having secretory cells.

Abstract

Tujuan penelitian ini adalah memperoleh konsentrasi ekstrak umbi kembang sungsang (Gloriosa superba) yang optimum untuk menghambat perkembangan jamur Colietotrichum capsici dan memperoleh kultivar tanaman terong (Solanum melongena) yang tahan terhadap penyakit antraknosa. Penelitian dilakukan di Laboratorium Botani, Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Lampung menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari 2 faktor dan 3 ulangan. Faktor pertama, konsentrasi ekstrak (A): 25%, 50%, dan 75%. Faktor kedua, kultivar terong (B): Wulung, Pahala dan Patria. Parameter pengamatan meliputi persentase kerusakan daun, tinggi tanaman, berat basah dan berat kering tanaman terong. Hasil percobaan menunjukkan bahwa ekstrak umbi kembang sungsang berpengaruh terhadap persentase kerusakan daun, tinggi tanaman, berat basah dan berat kering tanaman terong. Secara keseluruhan kombinasi perlakuan yang optimum untuk menekan perkembangan jamur C. capsici adalah konsentrasi 50% pada kultivar Wulung.

Abstract

Kakao merupakan komoditas unggulan yang tersebar hampir di seluruh Kabupaten di Lampung termasuk Kabupaten Pesawaran. Budidaya kakao di Pesawaran masih bersifat tradisional sehingga menyebabkan tanaman kakao rentan terserang penyakit seperti jamur dan akhirnya menurunkan mutu dan jumlah hasil panen. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis jamur patogen dan saprofit pada tanaman kakao (Theobroma cacao L.). Penelitian ini dilaksanakan di Kabupaten Pesawaran dan Laboratorium Botani FMIPA Universitas Lampung, dari bulan Juli sampai Desember 2012. Pengambilan spesimen dilakukan secara eksploratif di lima Kecamatan di Pesawaran yaitu Punduh Pidada, Gedong Tataan, Tegineneng, Padang Cermin, dan Kedondong. Pengamatan gejala serangan berupa munculnya miselium dan bercak pada organ tanaman kakao dilakukan secara makroskopis dan pengamatan secara mikroskopis dilakukan untuk mengamati bentuk, warna, dan ukuran spora. Dari hasil penelitian ditemukan 16 jenis jamur yang tergolong dalam 4 kelas. Satu jenis termasuk kelas Oomycetes, Satu jenis termasuk kelas Zygomycetes, 13 jenis jenis termasuk kelas Deuteromycetes dan satu jenis termasuk kelas Basidiomycetes.

Abstract

Curly red chili (Capsicum annuum L.) is widely used as industrial raw material because it has a spicy taste. The increasing demand for chili is not balanced with the level of production. Chilies are susceptible to disease, one of which is fusarium wilt. The magnetic field affected the physical and chemical properties of water so that it increased peroxidase enzyme activity and plant metabolism. This research was aim to know the protective effect seeds induced by 0.2 mT Magnetic Fiel had given to red curly chili (Capsicum annuum L.) sprouts to Fusarium oxysporum infection. This study was arranged in a completely randomized design (CRD) with 5 treatments consisting of M0F0 (control), M7F0, M7F60, M15F0, M15F60. M0 is a seed not induced by a magnetic field; M7 is seed induced by magnetic field 7 minutes 48 seconds, M15 is seed induced by magnetic field 15 minutes 36 seconds, F0 is sprouted not infected with F. oxysporum and F60 is sprouts infected with F. oxysporum for 60 minutes. Each unit is repeated 5 times. The results of the ANOVA showed that exposure to a magnetic field had a significant effect on increasing plant height at 21, 28, and 35 days after planting (HST); the wet and dry weight of 7 days old plants; and the content of chlorophyll a, b, and total before flowering 21 days after planting. Overall, the 0.2 mT magnetic field treatment for 7 minutes 48 seconds tended to give better results to increase the growth of chili plants against F. oxysporum infection.
