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.

Abstract

Plantain is a fruit commodity that has a high level of market demand, but the yield is low. To overcome this problem, tissue culture techniques are used to increase plantlet production in a short time. Plantain have parthenocarpy character, high sterility, and different levels of ploidy. Tissue culture with the addition of flame lily tuber biomutagen containing colchicine was used as a strategy to overcome the above constraints because it was thought to increase the production of polyploid banana plantlets. Changes in the anatomical and morphological structures are indicators of polyploidy. The purpose of this study was to obtain information on changes in the anatomical and morphological structures of plantain leaves as a result of giving in vitro plantlet propagation media as an indicator of the formation of polyploidy. Plantlets were grown on tissue culture media supplemented with three treatments: 10% flame lily tuber extract, 0.1% pure colchicine, and without addition (control). The parameters observed were epidermal cell size, stomata size, stomata index, number and leaf area. Epidermal cell size, stomata size and stomatal index were analyzed using range values ​​and mean values. The number of leaves, and the average wide of leaf, is then shown in the form of a bar chart. The results showed that administration of flame lily tuber extract was able to increase epidermal cell size, stomata size, wide of a leaf, and able to reduce the stomata index and number of leaves.

Abstract

Orchid is one of the largest groups of flowering plants that are in great demand by society. Besides, the various flowers with a long vase life, the price of orchids is also stable and affordable. Phalaenopsis and Dendrobium are the most popular types of orchids. To anticipate this, orchid cultivation needs to be improved. However, orchid cultivation is not always accompanied by the effort of disease prevention, particularly those caused by viruses. The virus that most infects orchids is the Odontoglossum ringspot virus (ORSV). Symptoms that appear on the leaves are chlorosis, mosaic with a pattern of lines, circles, and necrotic rings/rings. Control of viral infections can utilize organisms that are able to induce resistance, namely mycorrhizae. Mycorrhizae will penetrate into the root cortex tissue and provide nutrients for the orchid. Mycorrhizae that are quite often found are Rhizoctonia and are applied by induction to orchids. Induction was undertaken by planting orchids in Rhizoctonia inoculum until anatomically a peloton structure (solid coils) was formed on the orchid roots. The aim of this study was to study the response of orchid plants in the form of percentage incidence and intensity of the disease and the level of plant resistance to ORSV infection in Phalaenopsis amabilis and Dendrobium discolour which had been induced by Rhizoctonia. This research was conducted at the Laboratory of Botany, Biology, FMIPA, Universitas Lampung, using a factorial completely randomized design (CRD). Factor 1 was the type of orchid and factor 2 was mycorrhizal induction, virus inoculation, and a combination of both with 4 replications. The finding indicated that Phalaenopsis amabilis was more susceptible to ORSV infection than Dendrobium discolour based on a higher incidence and intensity of the disease. Mycorrhizal induction and virus inoculation (MAV) in Dendrobium discolour showed an increase of resistance response compared to Phalaenopsis amabilis.

Abstract

Pemberdayaan ekonomi keluarga merupakan bentuk kepedulian atas permasalahan kemiskinan dan penciptaan lapangan kerja. Ibu-ibu rumah tangga di pedesaan perlu didorong berwirausaha agar dapat menunjang ekonomi keluarga. Wirausaha budidaya tanaman hias cocok bagi ibu-ibu rumah tangga karena berskala rumahan dengan modal kecil. Perbanyakan tanaman merupakan salah satu komponen penting dalam budidaya tanaman hias untuk menjamin ketersediaan bibit berkualitas. Ibu-ibu rumah tangga di Desa Bandar Sari, Kecamatan Padang Ratu, Kabupaten Lampung Tengah sebagian besar berpendidikan rendah sehingga pengetahuan dan keterampilan budidaya tanaman hias mereka terbatas. Oleh karena itu kegiatan ini bertujuan untuk memberikan pengetahuan dan keterampilan teknik perbanyakan tanaman hias. Kegiatan dilaksanakan menggunakan metode ceramah dan demonstrasi. Hasil evaluasi kegiatan yang dilakukan melalui pretest dan posttest menunjukkan peningkatan pemahaman peserta yang cukup signifikan sebesar 76,96 %, yaitu dari nilai rata-rata pretest 48,84 meningkat menjadi 63,46 pada posttest. Sesi diskusi juga berlangsung kondusif dengan pertanyaan-pertanyaan peserta yang menunjukkan keingintahuan yang tinggi untuk memperoleh pengetahuan.
