Abstract

Tanaman biji pelir naga teragendakan salah satu macam tanaman yang n kepunyaan beberapa manfaat bagi manusia diantaranya adalah seumpama penawar dan perlengkapan sesaji kerumahtanggaan perayaan musim mentah China. Tanaman ini menginjak banyak dibudidayakan di Indonesia karena iklim di Indonesia nan sesuai cak bagi pertumbuhannya. Tanaman biji zakar dragon nan banyak dibudidayakan di Indonesia adalah tanaman buah naga putih dan tanaman biji pelir naga merah. Salah suatu sentra reboisasi biji kemaluan naga di Yogyakarta yakni di Sabila Farm Kecamatan Pakem.
Tujuan bermula penelitian ini yakni bakal mengetahui macam hama dan penyakit tumbuhan buah naga putih dan tanaman buah naga merah. Studi dilakukan di kebun Sabila Farm Kecamatan Pakem Kabupaten Sleman, Yogyakarta pada wulan September sebatas Nopember 2010. Macam-diversifikasi hama didapatkan bermula pemasangan haring kuning, liang perangkap dan lampu haring. Hama kemudian dihitung berdasarkan jumlah populasi dan kesungguhan serangannya. Jenis patogen didapatkan dengan melakukan pengamatan plong penggalan tanaman nan bergejala kemudian dilanjutkan dengan uji Hipotesis Koch. Selepas diketahui jenis kuman kemudian dihitung ketekunan serangannya di pertanian biji zakar naga. Jumlah populasi dan intensitas ofensif wereng dan penyakit pada tumbuhan buah ular besar kalis dan merah dianalisis dengan uji T taraf 5%.
Bermula hasil penelitian ini ditemukan insekta pada batang dan silang yaitu Valanga nigricornis (Acrididae) dan wereng dari kelas bawah Molusca, Acatina fulica (Achatinidae). Serangga pada buah adalah Drosophila melanogaster (Drosophilidae), Formica sp. (Formicidae), Planococcus sp. (Pseudococcidae) dan Diphucephala sp. (Scarabaeidae).
Secara statistik, rerata populasi A. fulica sreg batang dan cabang tumbuhan buah dragon lugu tidak farik secara nyata dibandingkan pada tanaman buah dragon ahmar. Populasi V. nigricornis hanya ditemukan pada batang dan cabang pohon buah dragon putih (0,25 ekor sendirisendiri tanaman). Hasil uji cakrawala rerata populasi Formica sp. lebih janjang secara berwujud pada biji kemaluan naga merah (34 ekor per tanaman) dibandingkan pada buah naga putih (24,63 ekor per tanaman). Rerata populasi D. melanogaster pada buah naga putih lebih tinggi secara substansial dibandingkan pada biji pelir naga merah, berturut-ikut adalah 24,25 ekor dan 21,38 ekor per tanaman. Serangga Diphucephala sp. dan Planococcus sp. hanya ditemukan lega buah naga putih, berturut-timbrung rerata populsinya adalah 0,5 ekor dan 0,5 ekor masing-masing tanaman. Hasil uji t rerata intensitas gempuran A. fulica lega batang dan cabang tanaman biji zakar naga berma makin tahapan secara nyata dibandingkan pada tanaman biji zakar naga tahir, berturut-turut adalah 11,88% dan 9,38%. Sedangkan rerata intensitas serangan V. nigricornis , Formica sp., D. melanogaster , Planococcus sp., dan Diphucephala sp. pada biji zakar ular besar putih dan buah dragon merah ialah 0%. Patogen yang disebabkan maka itu jamur C. gloeosporiodes hanya ditemukan pada batang dan silang tanaman buah naga sejati dengan rerata ketekunan serangan 11,10%. Serangan mikroba Pseudomonas sp. terdapat sreg batang dan cabang tumbuhan buah naga putih dan merah. Hasil uji lengkung langit menunjukkan rerata intensitas serangan patogen Pseudomonas sp. pada batang dan cabang pohon buah naga merah lebih janjang secara nyata dibandingkan pada batang dan cabang tanaman buah naga bersih, berturut-turut adalah 31,25% dan 18,75%. Pada buah naga safi dan buah naga biram tidak ditemukan gejala gempuran patogen serabut maupun bakteri.

English Abstract

Dragon fruit plant is a crop that have several advantages for human such as medical and equipment offering in the new year celebration of China. This plant has been cultivated in Indonesia because Indonesian climate is suitable for dragon fruit growth. Dragon fruit species which many cultivated in Indonesia are white and red naga fruit. One of centers of naga fruit cultivation in Yogyakarta is in Sabila Farm , Pakem sub district.
The aim of this research were to know pests and diseases on two kinds of dragon fruit. This research was done in Sabila Farm garden in Pakem, Sleman Yogyakarta, started from September mencicil November 2010. Pests population obtained from installation of yellow trap, pitfall trap and light trap. Pests population is then calculated based on the number and intensity of attacks. Kind of pathogens obtained by making observations on parts of plants of symptoms followed by a test Kochs postulates. After kind of pathogens was known, intensity of their attack on dragon fruit plant are calculated. The number of population and intensity of pests and diseases in plants of white and red dragon fruit was analyzed by N test level of 5%.
The research found insects on stem and branch, there were Valanga nigricornis (Acrididae) and Molusca was Acatina fulica (Achatinidae). Insect on fruit were Drosophila melanogaster (Drosophilidae), Formica sp. (Formicidae), Planococcus sp. (Pseudococcidae) and Diplucephala sp. (Scarabaeidae).
Statistically, average the population level of A. fulica on stems and branches of white dragon fruit plants did not differ significantly than the red naga fruit plants. Population of V. nigricornis only found on stems and branches of white dragon fruit plants (0,25 individuals per plant). T-test results showed that the average population of Formica sp. significantly higher on red dragon fruit (34 individuals sendirisendiri plant) than on white dragon fruit (24,63 individuals per plant). The average population of D. melanogaster on white dragon fruit was higher than on red dragon fruit 24,25 and 21,38 individual per plant respectively. Diphucephala sp. and Planococcus sp. only found on white hantu bumi fruit were 0,5 and 0,5 individuals per plant respectively. Ufuk test results showed that the average attack intensity of A. fulica on stems and branches of red dragon fruit plants was significantly higher than on stems and branches of white dragon fruit plants were 11,88% and 9,38% respectively. While the average attack intensity of V. nigricornis , Formica sp., D. melanogaster , Planococcus sp., and Diphucephala sp. on white and red naga fruit were 0%.
Pathogen caused by fungi of Colletotrichum gloeosporiodes (Glomerellaceae) only found on stem and branches of white dragon fruit plants with average attack intensity was 11,10%. Bacteria Pseudomonas sp. was found on stem and branches of white and red dragon fruit plant. T test result showed that the average attack intensity of Pseudomonas sp. on stem and branches of red naga fruit plant was significantly higher (31,25%) than on stem and branches of white dragon fruit plant (18,17%). On white and red naga fruit weren’lengkung langit found symptoms that caused by fungi or bacteria pathogen.
