Abstract

Two consecutive experiments that aimed to investigate effects of basal media and activated charcoal (AC) on (1) in vitro seed germination and in vitro seedling growth of Phalaenopsis hybrids were conducted. Phalaenopsis seeds taken from sterilized ripe pods were sown aseptically on MS or Growmore medium with or without 2 g/l AC, then the protocorms produced were counted after two months of culture. The same combinations of basal media and AC were used to grow protocorms produced from previous experiment for another two months, then the growth of seedlings were measured. The two experiments were arranged in a completely randomized design with three replicates. Each experimental unit consisted of four culture bottles each of which contained the same amount of seeds (in the first experiment) or five protocorms (in the second experiment). Data were subjected to analysis of vari-ance and if there was any significant F result (s), the means were separated using least significant difference at P? 0.05. Results of the first experiment showed that for in vitro germination of Phalaenopsis seeds, Grow-more medium produced significantly higher number of protocorms campared to MS, and addition of AC in both media significantly decreased the number of protocorms. Results of the second experiment showed that for in vitro growth of Phalaenopsis seedlings, either MS or Growmore medium resulted in the same seedling growth. However, addition of 2 g/l AC in the media significantly increased seedling growth as shown by higher values in plant height, number and length of roots as well as seedling fresh weight. So, it was concluded that Growmore medium was better than MS for in vitro seed germination and the same as MS for seedling growth of Phalaenopsis. The addition of AC in the medium was inhibitory for seed germination, but stimulatory for seedling growth. Keywords: activated charcoal, basal media, Phalaenopsis, seed germination, seedling growth.

Abstract

Tuberose (Polyanthus tuberosa L.) is a popular ornamental plant in Indonesia as cut flowers and sowing flowers. It can be used as potted flowers by making the flower stalks shorter. One way to get tuberose that have criteria as potted flowers is by administering growth inhibitors using Paclobutrazol. This research was conducted at the Greenhouse of the Horticultural Building, Faculty of Agriculture, University of Lampung in November to August 2017, aimed to determine the effect of the concentration of paclobutrazol on the growth and appearance of tuberose and to determine the best concentration of paclobutrazol in the appearance of potted tuberose. This study used a randomized block design (RCBD) with a single treatment with 6 levels of paclobutrazol concentration, namely 0, 75, 150, 225, 300, and 375 ppm with 3 replications. Homogeneity of variance was tested by Bartlett test and additivity was tested by Tukey test. Then, it was continued with the F test and with the Least Significant Difference test (LSD) at the 5% level. The results showed that administration of paclobutrazol was significantly affected pseudo stem circumference and all variables of generative growth except the length of the florets. The concentration of paclobutrazol up to 375 ppm has not obtained optimum results. Keywords: Concentration, growth, paclobutrazol, tuberose

Abstract

T. padwickii merupakan jamur utama terbawa benih pada padi yang dapat menyebabkan penurunan daya kecambah, viabilitas dan vigor benih. Sampel benih padi diuji terhadap infeksi penyimpangan warna gabah berdasarkan sistem standar evaluasi padi (SES, IRRI). Bibit padi kultivar IR 64 dan Cisadane dengan kadar air awal 14%, diinokulasi suspensi spora T. padwickii, dengan lama perendaman masing-masing 3, 6, 12, 24 and 48 jam. Hasil penelitian menunjukkan keparahan penyakit, tinggi tanaman, dan bobot gabah sangat dipengaruhi oleh T. padwickii. Tingkat infeksi yang tinggi lebih banyak teramati pada kultivar IR 64 dibanding Cisadane. Semakin lama perendaman dengan suspensi spora T. padwickii cenderung meningkatkan keparahan penyakit. Nilai rerata infeksi penyimpangan warna gabah meningkat lebih dari 4% pada inokulasi T. padwickii dengan lama perendaman selama 3 sampai 24 jam. T. padwickii fungi was observed in irregular shaped at rice seed with typical infection (pink color seeds); Morphologically single cell conidia of T. padwickii were estimated to have size of 1.6 x 7.5 μm in length.Kata kunci: Penyimpangan warna gabah; T. padwickii, patogen tular benih

Abstract

Utilization of rhizosphere microbes such as arbuscular mycorrhizal fungi (AMF) and mercury-resistant bacteria (MRB) is one of the alternative technologies that can be used synergisti-cally to overcome the main problem in biologically rehabilitation of marginal and mercury (Hg) contaminated tailings in ex gold mining area. The research was aimed to get an effective combination of AMF isolates (Glomus sp. SS11, Glomus sp.SS15, Glomus sp.SS18) with MRB isolates (Bacillus sp. HgTA1 and Pseudomonas HgRA) in supporting seedlings growth of sengon laut (Paraserianthes falcataria (L.) Nielsen) and sengon buto (Enterolo-bium cyclocarpum Griseb) in mercury-contaminated tailings. Dual inoculation of Glomus sp. SS15 with Bacillus sp. HgTA1 or Pseudomonas sp. HgRA isolates; dual inoculation of Glomus sp. SS18 with Bacillus sp. HgTA1 or Pseudomonas sp. HgRA isolates; single inoculation or dual inoculation of Glomus sp. SS11 with Pseudomonas sp. HgRA isolates were proven to be very effective in increasing P. falcataria seedlings height. However, only single inoculation of Bacillus sp. HgTA1 isolate was effective in increasing E. cyclocarpum seedlings height. Hg accumulation in plant tissue of P. falcataria and E. cyclocarpum, either with or without rhizosphere microbial inoculation, indicated that both plants were highly potential as Hg phytoextraction or phytostabilization agents.  Key words: arbuscular mycorrhizal fungi, Enterolobium cyclocarpum Griseb, mercury, mercury-resistantbacteria, Paraserianthes falcataria (L.)

Abstract

Propagation by corm division of banana provides an opportunity to get the seedling in large quantities, but need technology to promote the growth of spur on the buds that are still dormant. Research conducted in 2010 in the greenhouse of Faculty of Agriculture, University of Lampung aimed to determine the effect of growing media and concentration of BA in Yellow banana?s Ambon multiplication by corm division. The study con-sisted of 2 subtitle designed in perfectly with the design of randomized groups factorial (4x2) which is repeated 3 times. The first factor is the same in both experiments: BA concentrations (0, 50, 100, 200 mg / l) and the second factor in the first experiment: the type of media (sand mixed with rice husk and sand with compost 1:1) and in Experiment II: cleavage divition (four and eight parts). Planting material in Experiment I, hump into four sections and planting medium used in Experiment II, a mixture of sand and rice husk 1:1. The variables measured were: time emerged shoots, number of shoots, and shoot height, diameter of the base of shoots, number of leaves, leaf width, number of roots, and the average length of the roots. Data were analyzed by using a variety of software Mini Tab, followed by a test of least significant difference (LSD) 5%. The results showed that: (1) growth of shoots on a mixture of sand and compost media better than husk fuel mixture, as well as in treatment 4 parts division hump better than 8 parts. But seen the efficiency of shoot growth, division 8 section bits more efficient because it produces more shoots (4.8 shoots) without giving BA, whereas if split 4 parts need BA a concentration of 50 ppm. Giving BA 50 ppm in sand and compost to increase the number of shoots indicated for the highest percentage (91.67%). Keywords: Yellow banana?s Ambon, corm divition, benzyladenine, growing media.
