Abstract

ABSTRACT Altitude in the tea plantation effect physiological processes of the  tea plants. That will effect pruning time of tea plant.  Therefore,  this research is carried out to find: 1) Physiological process of tea plant grow in different ages of pruning and altitudes, 2) Optimum age of pruning at differentaltitude. The research was carried out in tea plantation in Inti PT Pagilaran Batang from July to November 2010. The research was conducted in Oversite design using 2 factor, hight place of plantation area (altitude) i.e 700-900 m asl (above sea level), 900-1100 m asl, 1100-1350 m asl and age of prune i.e 1-year after pruning, 2-years after pruning, 3-years after pruning and 4-years after pruning. All the combination treatment was replicated in 3 blocks. The observation were done on several variable of physiologi, growth and yield.All data were analyzed by variant analysis of oversite (multilocation) levels of 5%, followed by Duncant multiple range test level of 5% if there was significantly different in varian analysis.The results showed that at an The 3-years after pruning tea plants showed the lowest characters in fresh and dry shoot weight. Its pointed out bynumber of accumulative pecco shootthan 1, 2 and 4-years after pruning.

Abstract

ABSTRACTThere are many shallot cultivars cultivated in Java with varying greatly morphological traits and yield. Morphological and yield variation indicate that there are genetic variation and varying in resistance to pest and disease. One of major disease that cause yield losses of shallot is Fusarium Basal Rot (FBR) caused by Fusarium oxysporum f. sp. cepae (Foc). The pathogen could cause yield losses of shallot in field up to 90%.The number of sixteen shallot cultivars were collected and studied for determining polymorphisms of nuclear based on Random Amplified Polymorphism DNA (RAPD) and the morphological traits. Potted research was conducted at greenhouse from December to February 2012, in Department of Agriculture, Universitas Gadjah Mada (UGM), Yogyakarta. Four shallot cultivars were selected for study the response to Foc under biofertilizer application. They were Kuning, Trisula, Tiron, and Crok cultivars. The field experiment was carried out from June to August 2012 at the Agricultural Training, Research and Development Station (ATRD/KP4) in Kalitirto, Sleman, Yogyakarta. The research design was split plot 4 x 4, with three replications. The plots consisted of shallot which cultivated in Foc inoculation, biofertilizer application, combination of Foc inoculation and biofertilizer application, and without any treatments. The subplot consisted of shallot cultivars. All data were statistically analyzed using the variance analysis. Standard error was tested to determine the significant differences among treatment means.Similarity coefficient among shallot cultivars as revealed by UPGMA cluster analysis of RAPD markers generated to molecular dendogram. The similarity of genetic dendogram ranged from 0.85 to 0.66 and separated of cultivars into two groups. Based on morphological analysis, there were variations of all variable that tested. Mophological dendogram made possible to identify four group.Fusarium Basal Rot (FBR) incidence caused by seedborne was 6.94%. Biofertilizer application could not decrease significantly FBR incidence but it could increase number of bulb per plant in Crok and Kuning cultivars. FBR incidence with 43.75% caused by Foc inoculation was significantly decreasing plant height, number of bulbs, diameter of bulbs, and length of bulbs. However, yield of shallot decreased significantly  from  1.05  kg/m2 to  0.63  kg/m2 when  the  shallot  plantation  was inoculated by Foc. The shallot plantation was inoculated by Foc under biofertilizer application did not show significantly decreasing FBR incidence and increasing the yield. FBR incidence and yield of Trisula, Crok and Tiron cultivars did not show difference significantly from Kuning cultivar as susceptible to Foc.Key words: cultivar, shallot, RAPD, Fusarium oxysporum f. sp.

Abstract

INTISARIBiji  bawang  merah  sebagai  bahan  tanam  memiliki  posisi   strategis beberapa tahun terakhir. Meskipun demikian, kemampuan berbunga tanaman bawang merah cukup terbatas khususnya pada penanaman di dataran rendah. Di dataran  rendah,  jumlah  tangkai  bunga  yang  dihasilkan  per  individu  tanaman sangat terbatas. Beberapa hasil penelitian sebelumnya memberikan informasi bahwa perlakuan vernalisasi mampu meningkatkan pembentukan bunga pada tanaman bawang merah, khususnya pada penanaman di dataran tinggi. Pada penanaman bawang merah di dataran rendah, informasi mengenai pengaruh perlakuan vernasilasi terhadap kemampuan berbunga hingga saat ini belum ada. Oleh karena itu, penelitian terkait hal tersebut cukup penting untuk dilakukan. Tujuan penelitian adalah 1) mengidentifikasi pengaruh lama vernalisasi terhadap pertumbuhan, pembungaan serta hasil umbi dan biji bawang merah dan 2) menentukan lama vernalisasi yang optimum untuk meningkatkan pertumbuhan, pembungaan serta hasil umbi dan biji bawang merah.  Penelitian dilaksanakan di Kebun Tridharma Fakultas Pertanian UGM, Banguntapan, Bantul, Yogyakarta dari bulan Oktober 2011 – Januari 2012. Percobaan disusun dalam rancangan acak kelompok  lengkap  faktorial  dengan  3  blok  sebagai  ulangan.  Faktor  pertama adalah varietas yaitu: Katumi, Biru, Bima dan Tiron. Faktor kedua adalah lama vernalisasi yaitu tanpa vernalisasi, vernalisasi selama 4 minggu, 5 minggu, dan 6 minggu. Pengamatan dilakukan terhadap tinggi tanaman, jumlah daun, jumlah anakan, jumlah umbi, diameter umbi, berat segar, dan berat kering jemur umbi. Analisis pertumbuhan meliputi indeks luas daun, laju asimilasi bersih, laju pertumbuhan tanaman, dan indeks panen. Hasil penelitian memberikan informasi bahwa lama vernalisasi yang optimal untuk peningkatan berat segar umbi varietas Bima adalah 12-13 hari, dengan indikasi peningkatan berat segar umbi hingga mencapai 14,47 g. Berat kering umbi terbaik dihasilkan oleh varietas Bima (6,00 g) dengan lama vernalisasi 13-14 hari. Pembungaan tidak terjadi pada semua perlakuan  yang diuji sehingga dapat disimpulkan bahwa perlakuan vernalisasi tidak mampu menginduksi pembungaan pada tanaman bawang merah yang ditanam di dataran rendah yang dikarenakan faktor lingkungan (suhu, angin) rata- rata cukup tinggi dan panjang penyinaran yang rendah pada saat penelitian berlangsung.Kata kunci : bawang merah, varietas, vernalisasi, pembungaan.

Abstract

True Shallot Seed (TSS) is a planting material for shallots in the forms of seeds. It shows a visual appearance of the fresh green shoot even though in the harvest season. This condition indicates that TSS still has potential assimilates which should be optimized for bulbs formation. Paclobutrazol is increasing assimilate translocation from source to sink by activating the sucrose transporter enzyme and changing the phytohormones balance. The study aimed to find out how paclobutrazol increased bulb yield on TSS by analyzing the closeness in the relationship between and the influence of physiological property variables and growth analysis. The study was conducted at Gadjah Mada University experimental field, Yogyakarta, from September to November 2017. It was arranged in a Randomized Complete Block Design with three replications. The first factor included the paclobutrazol concentration (0, 15, 30 and 45 mg L-1), while the second one included TSS cultivars (Tuk Tuk, Sanren and Lokananta). Correlation and regression were used in the data analysis. The results revealed that paclobutrazol significantly affected the physiological properties and the growth of TSS, instead of cultivars. Regression analysis showed that the effect of the concentration of the applied paclobutrazol formed quadratic pattern, where most observed variables had a positive correlation with shallot productivity. Paclobutrazol increased bulb yield by maintaining shoot biomass duration (SBD) and chlorophyll content which had a positive and linear effect on plant growth rate (PGR). The PGR might increase bulb yield per planting hole and indirectly increase its productivity. Paclobutrazol application at 15-30 mg L-1 could be used to improve bulb yield in TSS.

Abstract

Artemisia cina is a medicinal plant species which produces bioactive compound potential to anti-tumor, antifungal and antibacterial medicines. This study was aimed to obtain A. cina polyploid plants through a treatment of growth regulators in shoot culture. The shoot were treated in 1; 15; 2; and 3 mg L-1 of 2,4-dichloro phenoxy acetic acid (2,4-D) combined with 1; 1.5; 2; 3 mg L-1 of Benzyladenine (BA) for 28 days. Chromosome analysis showed that the highest polyploidy percentage, 23%, was reached in the treatment of 2 mg L-1 of 2,4-D combined with 1 of BA mg L-1. The polyploidy level varied, comprising 2n=3x, 2n=4x, 2n=5x, 2n=6x, with the highest polyploidy level percentage, 28.57%, and it was attained in the tetraploid (2n=4x). Polyploid plants had larger leaves area, larger stomatal size, and higher chlorophyll content than diploid plants. However stomatal density of polyploidy plants was lower than that of in diploid plants.Keywords: 2,4-D, Artemisia cina, BA, polyploidy
