Abstract

Morphological characters are basic characters to identify rice cultivars. The information of glutinous rice cultivars in Ponorogo is still very limited, therefore the exploration and characterization of the local cultivar are needed. The research aimed to explore and identify local cultivars based on morphological characters of plant, grain, and milled rice. The research was conducted on March-October 2018 at elevens subdistricts in Ponorogo. There were eleven cultivars have been collected and characterized, namely five white glutinous rice cultivars (Latisa, Tawon, Semok, Pelem, Genjah), three red glutinous rice cultivars (Garingan, Merah Pendek, Jowo), and three black glutinous rice cultivars (Wilis, Gundik, dan Gontor Bulu). The eleven cultivars were varied on plant height, panicle length, flowering time, number of tillers, grain size and shape, and the color of aleurone. The analysis of diversity and similarity on characters showed that all cultivars could be classified into four different groups. The first group was Latisa (Gontor Bulu), the second was Tawon group (Pelem), third was Genjah group (Garingan, Merah Pendek and Jowo), and the fourth was Wilis group (Gundik). Keywords: aleurone , diversity, exploration, rice grain, similarity

Abstract

The Khapra beetle Trogoderma granarium Everts is very destructive pest in various stored product and nominated as one of the hundred worst invasive species in the world. The study of starvation and infestation behaviors are important for improvement of insect control method. This study represent the number of molting as fact of regressive molting in starved condition, the larva of T. granarium within 68 days periods can be molted 1-3 times. The infestation behavior on three diets treatment presented. In grain wheat their larva are laid off the casting skin over the surface of product and distributed randomly in whole part of stored product. Respectively in flour casting skin are laid down in bottom of the container as effect of feeding. In flour the casting skin are laid on mostly over surface of the flour mixed with frass. In toilet tissue the infestation is present in hole over the surface and randomly position of casting skin.

Abstract

A survey of phytopathogenic fungi and Oomyceteswas conducted in Riyadh, Kingdom of Saudi Arabia duringOctober 2008 – May 2009. Total of 223 samples were collectedfrom four regions; Al-Kharj, Oyaynah, Old Diriyah, and Al Amariyah. Isolation was done using Potato Dextrose Agar(PDA). Infected parts were cut then sterilized in chlorox(10%), then were put in petridish that contain PDA andincubated at 25-27 °C. A total twelve genera of fungi andsingle genera of Oomycetes were isolated from the infectedplants and identifi ed as Fusarium spp., Alternaria spp.,Helmintosphorium (Bipolaris) spp., Sclerotium spp., Rhizoctoniaspp., Cladosporium spp., Mauginiella scattae, Erysiphe spp.,Leveillula spp., Macrophomina phaseolina, Ustilago spp.,Ulocladium spp., and Phytium spp.

Abstract

Salah satu masukan teknologi dalam meningkatkan mutu buah dan system produksi yang efisien juga berkelanjutan adalah aplikasi pupuk hayati mikoriza. Aplikasi mikoriza mampu meningkatkan mutu buah; kandungan gula pada sari buah jeruk dan warna buah jeruk. Aplikasi mikoriza juga dapat meningkatkan jumlah buah dan berat buah pada tanaman semangka, tanaman cabai, dan bawang merah. (Sastrahidayat, 2011). Kemampuan satu jenis mikoriza dapat berasosiasi dengan beberapa tanaman cukup luas, tapi kesesuaiannya dalam bersimbiosis dengan tanaman sangat dipengaruhi oleh berbagai kondisi tanah, jenis tanah dan jenis tanaman. Simanungkalit (2000) mengemukakan spesies mikoriza dapat mengkolonisasi secara efektif pada tanaman tertentu tetapi belum tentu efektif pada tanaman lain. Eksplorasi mikoriza dari berbagai tempat dan aplikasi mikoriza pada tanaman melon sebagai teknologi pupuk hayati penting untuk dilakukan penelitian. Sehingga didapatkan beberapa genus mikoriza dan mendapatkan genus mikoriza yang cocok untuk tanaman melon. Metode untuk mendapatkan beberapa genus mikoriza dilakukan dengan cara eksplorasi, identiikasi dan koleksi di lahan sawah dan lahan perkebunan di Kabupaten Ponorogo Jawa Timur. Metode Eksplorasi menggunakan ayakan basah (Wet sieving) dan teknik decanting. Metode identifikasi dilakukan berdasarkan “Species Guide Manual” yang disusun oleh Schenck dan Peres (1990) dan dicocokkan dengan INVAM 2017. Sedangkan untuk mengetahui kecocokan genus mikoriza dengan tanaman melon dilakukan dengan parameter infeksi genus mikoriza pada akar melon, berat akar, dan panjang akar. Infeksi mikoriza diamati dengan metode Phyllip and Hayman (1970). Analisis data dilakukan dengan ANOVA dan dilanjutkan dengan uji LSD pada taraf kepercayaan 5%. Hasil eksplorasi genus mikoriza pada lahan sawah  dan lahan perkebunan berhasil didapatkan 7 genus antara lain yaitu genus glomus, Gigaspora, Acaulospora, Archaeospora, Paraglomus, Entrophospora dan Scutellospora dengan rata-rata spora 0,1 sampai dengan 5,3 spora/100gr sampel. Hasil uji kecocokan genus mikoriza terhadap tanaman melon adalah genus Scutellospora dan Glomus yang diisolasi dari rezospher tanaman melon di lahan sawah.
