Abstract

Field studies were conducted in two years using 638 F2 and 1185 F3 lines of selected 16 F1 and 15 F2 parent lines (³80 pods plant-1) to evaluate pod number and CO2 exchange rate (CER) as selection criteria. Pod and seed number, and seed weight of individual lines were observed during harvesting time, and CER of randomly selected 32 F2 and 30 F3 lines was measured at initial seed filling stage.  The selection of F2 lines based on pod number to generate F3 lines increased the average of seed yield by 39%, and pod number by 77% in F3 lines compared with F2 lines. A close relationships was found between seed weight and pod or seed number per plant.  Net CER responded sensitively to a reduction of light in a short-term and showed 78% of F2 lines and all F3 lines with maximum CER (Pmax)³20 mmolCO2.m-2.s-1. The ratio of pod number per plant and Pmax varied between lines and were used to group lines resulting in close relationships between Pmax and pod number. It is concluded that the use of pod number and CER (Pmax) as selection criteria offers an alternative approach in soybean breeding for high yield.  Keywords: CO2 exchange rate (CER), Glycine max L.

Abstract

Mosaik adalah gejala penyakit yang sering ditemukan pada tanaman cabai merah (Capsicum annuum) dan umumnya disebabkan oleh infeksi virus seperti Tobacco mosaic virus. Infeksi yang berat bahkan dapat mengakibatkan tanaman menjadi kerdil dan mengalami kehilangan hasil yang nyata. Metode serologi dan molekuler sudah banyak digunakan untuk mendeteksi virus tetapi pengerjaannya cukup menyita waktu, relatif kurang efisien untuk sampel yang banyak, dan bersifat destruktif pada tanaman. Di sisi lain, pengamatan gejala secara langsung terkendala oleh kemampuan visual manusia dan gejala laten pada tahap awal infeksi. Oleh karena itu, metode deteksi berdasarkan kemampuan tanaman menyerap dan merefleksikan berbagai spektrum cahaya matahari, seperti normalized difference vegetation index (NDVI) berpotensi untuk dikembangkan. Penelitian ini bertujuan untuk mengevaluasi potensi single image-NDVI sebagai varian NDVI untuk pengembangan deteksi dini gejala mosaik pada cabai merah. Tahapan utama penelitian ialah perekaman citra tanaman cabai merah yang tidak diinokulasi virus (V0), diinokulasi (V1), dan minim hara (M) menggunakan kamera RGB tanpa modifikasi dan filter lensa untuk menangkap reflektansi cahaya biru dan Near-Infrared. Selanjutnya dilakukan pengolahan citra menggunakan plugin Photo Monitoring pada aplikasi Fiji-ImageJ. Perekaman dilakukan mulai 1 hari setelah inokulasi (HSI) sampai gejala terlihat kasat mata. Hasil penelitian menunjukkan bahwa terjadi tendensi peningkatan nilai NDVI terintegrasi pada semua perlakuan. Namun, tendensi peningkatan pada V1 tidak nyata dibandingkan dengan V0 dan M. Selisih rata-rata nilai NDVI terintegrasi antara V1 terlihat sangat nyata dibandingkan dengan V0 (pada 5 HSI) dan M (pada 1 HSI). Tingkat sensitivitas, spesifisitas, dan akurasi metode ini berkisar antara 80–90 % pada 5 HSI.

Abstract

The decline in the production of oil palm yields in Tomuan Holbung Village,Bandar Pasir Mandoge Subdistrict, Asahan District was identified as a result of a very highlevel of pest infestation. Pests that are often found and becomes the problems are Setothoseaasigna larva. Controlling these pests is a relatively high cost through the application ofchemical synthetic pesticides. The purpose of this research to determine the best formulationof botanical pesticides and their influence in reducing Setothosea asigna larva pests.Botanical pesticides which will be tested in this research are based from garlic, lemongrassleaves, pepper seeds, turmeric, tobacco leaves and papaya leaves. Formulations from eachsource of vegetable material were put into the leaves of palm plants and then tested onSetothosea asigna larva. The parameter observed in this study was the level of palatability ofSetothosea asigna larva. The observations made were based on the level of decrease in thepercentage of feeding activity, the weight of feed (palm oil plant leaves) that were consumedby the Setothosea asigna larva in the period 1-6 days after application. The results of thestudy showed that all treatments of botanical pesticides consisting of: 1) garlic, 2) lemongrass leaves, 3) pepper seeds, 4) turmeric tubers, and 5) tobacco leaves were significantlydifferent from without treatment or control. Then the results of the study also showed that theapplication of botanical pesticides affected the palatability of the Setothosea asigna larva,which accelerated death, appetite and decreased eating activities. The best treatment ofvegetable pesticides from tobacco leaves in controlling the Setothosea asigna larva'spalatability. Setothosea asigna larva die on first day, It don’t want to eat after the applicationof botanical pesticides, and the level of eating activity decreases to 100%.Keywords : Setothosea asigna larva, botanical pesticide, palm plants
