<p><em>Perbanyakan pisang biasanya dilakukan dengan menggunakan anakan-anakan pisang yang tumbuh disekitar induk tanaman. Selain dengan perbanyakan pisang dengan cara vegetatif , pisang juga bisa dibudidayakan dengan teknik kultur jaringan dan dengan teknik ini diharapkan akan menyelesaikan masalah pengadaan bibit tanaman pisang. Kultivar pisang lokal yang prospektif untuk dikembangkan untuk buah segar (banana) jenis pisang Ambon Kuning dan pisang olahan (plaintain) adalah jenis Kepok Kuning. Persoalan yang dihadapi mitra adalah 1) masih menggunakan bibit-bibit pisang secara konvensional sehingga kebutuhan pisang dipasaran tidak diimbangi dengan produksi yang ada, 2) mitra belum mengetahui dan mengenal perbanyakan pisang secara kultur jaringan. Metode pendampingan kegiatan PKM ini adalah: 1) penyuluhan tentang pemanfaatan bioteknologi melalui penyediaan bibit pisang asal kultur jaringan, 2) pelatihan teknik aklimatisasi, dan 3) dilaksanakannya demonstrasi plot di lahan demplot untuk melihat keragaan (field performance). Kegiatan PKM ini dapat menambah pengetahuan petani dan wanita tani khususnya tentang penyediaan bibit-bibit pisang melalui kultur jaringan dan menghasilkan produk tambahan berupa pupuk Trichokompos TKKS.</em></p><strong><em>Kata kunci :</em></strong><em> Aklimatisasi, Kultur Jaringan, Pisang</em>
Konjac glucomannan has been commercially produced and used as functional food, food additives, food supplements, pharmaceutical and cosmetic, and biomaterials. Despite intensive and advance research at postharvest stage, knowledge on cultivation of konjac plants has been limited. This research covered current issues associated with selecting agronomically the most suitable planting material, shading effects on shoot emergence and growth characteristics, and non-destructive area estimation of the compound leaf in the konjac plants. Planting materials used were 81 true seeds, 81 bulbils and 81 cormels. Results of this study indicated that bulbil was a suitable planting material based on its early shoot emergence and size of above ground organs. Shading at 50 and 70 % exhibited a better performance in time of emergence and growth characteristics than konjac plant fully exposed to sunlight, even though the differences were not statistically significant. Total leaf blade area (LA) of the irregular konjac compound leaf can be accurately (R2 = 0.9932) and consistently estimated using the 0-intercept linear model and the multiplication product of total midrib length and average width of all leaflets (TLM×AWL) is used as predictor. The recommended formula is LA = 0.6761(TLM×AWL).
HIGHLIGHTS
Shoot emergence in konjac plant was significantly earlier if the true seed was used rather than bulbil and cormel as planting materials
Plant grown using cormel and bulbil exhibited larger shoot and corm compared to those grown using true seed
Shading at 50 and 70 % increased length of the pseudo-stem, total number of leaflet, and other morphological characters
Total midrib length of all leaflets and average of all leaflet width (TLM×AWL) could be used as predictors for accurate LA estimation
GRAPHICAL ABSTRACT
Abstract. The yield of rice crop was highly affected by water availability and drought condition . The effort was done to seek local varieties of rainfed rice which tend to be tolerance to drought condition. This research objective was to seek some local varieties of rainfed rice that tolerance to several drought conditions. This research was conducted at Farm
