Abstract

The objective of this research is to investagate the level of drought resistance of some local corn cultivars from Timor in the germination phase. The single factor study is the genotype of maize origin of Timor which consists of 22 cultivars. The study was arranged in a complete randomized design (RAL) and repeated 3 times. The observed variables were germination (DB) expressed in% and normal dried germination weight (BKKN), expressed in grams. The analysis of heritability values (h2) was measured by comparing the genotypes of the various phenotypes (total). The h2 value was greater than 0.5 indicates a genotype diversity of drought resistance. Furthermore, the drought resistance rating based on DB difference (DB aquades-DBPEG) and BKKN aquades - BKKN PEG (BKKN aquades - PEG) difference. The result of the research shows that the calculation of h2 value of 22 East Maize cultivars on DBPEG and BKKNPEG measurements is 0.721 and 0.938, respectively, which means that there is a diversity of drought resistance of 22 cultivars tested. Muke Merah corn cultivars (flowers) Muke White (flowers), White Malacca 1, White Haikesak, White Tastim, and Red Fatumonas (flowers) have good potencial to be used as ingredients in breeding programs to obtain drought tolerant varieties of maize. Key Word: Corn, Genotype selection, drought resistance, germination

Abstract

Palm is one of the ornamental plants which attracted many people. It is a tropical and subtropical plant which requires full sun. Princess Palm (Veitchia merilli) is one of the most desirable palm and is potential as ornamental plants of high economic value. It  is one of  palm species which is propagated by seed. Seed should germinate quickly in order to get palm seedlings in a short time. Slow germination is an obstacle in the cultivation of palm,  because the palm seed coat is very hard, thus inhibiting seed germination process. This research aimed at determining the influence of chemical treatments on the germination of Princess Palm.  This research was conducted in the screen house of laboratory of horticulture Kupang State Polytechnic of Agriculture between June and August 2015. The research design used in this study was randomized block design (RBD). The treatments used were: no chemical treatment, H2SO4, KNO3 and combination of  H2SO4 and KNO3. The results showed  that the chemical treatment affects the germination and seedling growth of Princess Palm. H2SO4 and KNO3 treatment gives best germination palm especially in terms speed growth and value of germination.  Keywords: Palm, Chemical Treatment, Germination, Seed

Abstract

Penelitian bertujuan untuk mengetahui pengaruh berbagai konsentrasi pupuk organik cair kotoran kelelawar terhadap produksi dan mutu fisiologis benih kangkung. Penelitian faktor tunggal yaitu konsentrasi pemberian pupuk organik cair kotoran kelelawar yang terdiri dari 6 taraf yaitu 0, 50, 100, 150, 200, dan 250 ml POC/liter. Penelitian disusun dalam rancangan acak kelompok (RAK) dan diulang 4 kali. Pengamatan dikakukan terhadap kandungan hara POC kotoran kelelawar dan tanah awal, kandungan hara tanah sesudah perlakuan, jumlah bunga dan buah per tanaman, jumlah biji bernas per tanaman, bobot kering biji per petak, daya berkecambah serta T50. Hasil penelitian menunjukkan konsentrasi POC kotoran kelelawar berpengaruh terhadap variable produksi (jumlah bunga per tanaman, jumlah buah per tanaman, jumlah biji bernas per tanaman dan bobot kering biji per petak). Konsentrasi POC kotoran kekelawar juga berpengaruh terhadap variable mutu fisiologis benih kangkung (daya berkecambah dan T50). Konsentrasi 150 ml POC/liter memberikan hasil terbaik, ditunjukkan oleh tolok ukur jumlah bunga per tanaman ( 58,4 kuntum), Jumlah buah per tanaman (54,6), jumlah biji bernas per tanaman ( 33,4 buah), bobot kering biji per petak (106 g), tetapi dan daya berkecambah tertinggi pada konsentrasi 200 ml POC/liter (85,5 %).
