K am al b en y am i n E s h o S af w a n H as i m S a eedEffect of humic aci d on growth and y ield of three culti v ars of summer squash ( Cu curbita pep o L.) ABSTRACT:The e xperim ent w as carried out in the private vegetable farm , Som ail, Duhok governm ent, during autum n growing season 2015, The aim of the experim ent w as to study the effect of humic acid on grow th and yield of three cultivars of summ er squash (Cucurbita pepo L.). The experim ent w as a split plot design within three replicates, in this study, three concentrations of hum ic acid w ere used (0, 25 and 59 mg/ litter), and three cultivars of summ er squash w hich w ere (Alexandria F1, Khatoon F1 and Ardendo 174 F1). The data w as recorded on: fresh and dry w eight /plant, num ber of m ale , female flow ers, sex ratio, length, diam eter, w eight of fruit, num ber of fruit/plant and total yield/hectare. The results show ed that the concentration at 50 mg/litter of humic acid gave a significant increase in fresh, dry w eight /plant, fruit length, number of fruits /plant and total yield, the cultivar Ardendo 174 F1 gave a significant increase in m ost traits except the sex ratio and fruit diam eter, and the interaction between the 50mlg/litter of hum ic acid and cultivar Ardendo 174 F1 gave a significant increase in fresh, dry w eight /plant, female flow er /plant , num ber of fruit/plant and total yield/hectare. The results show ed that there w as higher positive phenotypic correlation coefficient between the total yield /hectare, fruit w eight with m ost traits.

“…Hal ini menunjukkan tanaman yang dilindungi dengan galur lemah menghasilkan lebih banyak jumlah buah daripada tanaman yang tidak dilindungi, sementara galur lemah tidak mengurangi bobot buah. Penggunaan galur lemah virus sajaseperti ZYMV-S, ZYMV-WK, ZYMV-2002, ZYMV-M dan GFLV-juga dilaporkan tidak mempengaruhi produksi buah (Kosaka et al 2006;Komar et al 2008;Bonilha et al 2009).…”

ABSTRAKInokulasi virus galur lemah sebelum inokulasi galur kuat adalah prinsip proteksi silang. Lima galur lemah Chili veinal mottle virus (ChiVMV), yaitu KAR, SPR, SKT, CSR, dan PGL digunakan sebagai agens proteksi silang untuk melindungi tanaman cabai dari infeksi ChiVMV-CKB. Inokulasi galur lemah secara mekanis dilakukan pada 7, 14, 21, dan 28 hari sebelum inokulasi galur kuat. Proteksi silang dievaluasi dengan mengamati gejala penyakit yang muncul dan bobot buah. Inokulasi ChiVMV galur lemah pada interval waktu 7 hari sebelum inokulasi ChiVMV galur kuat tidak mampu melindungi tanaman dari infeksi galur kuat. Pengaruh inokulasi galur lemah mulai tampak pada interval waktu 14, 21, dan 28 hari berupa penghambatan gejala penyakit dan produksi tanaman yang tidak berbeda nyata dengan tanaman sehat. Oleh karena itu, inokulasi ChiVMV galur lemah sebagai agens proteksi silang disarankan seawal mungkin sebelum terjadi infeksi oleh galur kuat.Kata kunci: cabai, galur kuat, gejala belang, inokulasi mekanis ABSTRACT Inoculation of mild virus strain prior to severe virus strain to protect plant against viral disease is the principle of cross protection. Five mild strains of Chili veinal mottle virus (ChiVMV), i.e. -KAR, -SPR, -SKT, -CSR, and -PGL were used as cross protection agent to protect chili pepper plants against severe strain infection of ChiVMV-CKB. The mild strains were inoculated mechanically prior inoculation of severe strain and the efficiency of cross protection was evaluated by observing symptom development and measuring crop yield. Inoculation of mild strains 7 days prior inoculation of severe stain was not able to protect the plant from infection of severe strain ChiVMV-CKB. Protective effect was observed when mild strains were inoculated at 14, 21, and 28 days prior inoculation of severe strain. Symptom development was suppressed or delayed, and crop yield was not significantly different with healthy plants. It was suggested that to obtain the best protection against severe strain, the mild strain should be applied as early as possible before the occurrence of severe strain infection.

“…Proteksi silang adalah strategi untuk melindungi tanaman dengan memanfaatkan virus strain lemah untuk mencegah infeksi virus strain kuat pada virus yang sekerabat. Proteksi silang telah dilakukan untuk mengendalikan beberapa penyakit penting seperti penyakit-penyakit yang disebabkan oleh papaya ringspot potyvirus (Bonilha et al 2009), tobacco mosaic tobamovirus (Lu et al 1998), citrus tristeza closterovirus (Costa & Muller 1980), cocoa swollen shoot badnavirus (Ollennu & Owusu 2003), dan zucchini yellow mosaic potyvirus (Kosaka et al 2006). Dilaporkan bahwa proteksi silang telah dilakukan lebih dari 10 tahun dan memberikan hasil yang memuaskan untuk menekan infeksi ZYMV pada melon (Bonilha et al 2009).…”

ABSTRAK. Salah satu virus utama yang menginfeksi tanaman cabai ialah Chili veinal mottle potyvirus (ChiVMV) yang potensial menyebabkan kehilangan hasil. Strategi pengendalian virus melalui proteksi silang mengandalkan kemampuan virus strain lemah dalam melindungi tanaman dari infeksi virus strain kuat. Penelitian dilakukan untuk mengeksplorasi isolat lemah ChiVMV pada pertanaman cabai di Jambi, Sumatera Barat, dan Jawa Barat, sedangkan deteksi ChiVMV dilakukan di Laboratorium Virologi Tumbuhan dan penularan ke tanaman cabai di Rumah Kaca Departemen Proteksi Tanaman, Institut Pertanian Bogor, dari bulan Februari sampai Juli 2011. Isolat-isolat ChiVMV dari tiap daerah berhasil ditularkan dan diperbanyak pada tanaman cabai rentan (Capsicum annuum L.) IPB C13 di rumah kaca. Berdasarkan gejala penyakit dan keparahan penyakit, isolat ChiVMV dapat dibedakan menjadi tiga kelompok yaitu isolat kuat (CKB), isolat sedang (CKW), dan isolat lemah (KAR, SPR, IVAK, SKT, LGM, SKR, CGN, CSR, dan PGL). Isolat-isolat lemah ChiVMV ini selanjutnya dapat digunakan sebagai kandidat agens proteksi silang dalam pengendalian penyakit belang yang disebabkan oleh ChiVMV. ABSTRACT. Asniwita, Hidayat, SH, Suastika, G, Sujiprihati, S, Susanto, S, and Hayati, I 2012. Exploration of Weak Isolates of Chili Veinal Mottle Potyvirus from Chili Peppers in Jambi, West Sumatera, and West Java. Chili veinal mottle potyvirus (ChiVMV) is known as an important virus infecting chili peppers and may cause significant yield loss. Management strategy of virus diseases using cross protection relies on the ability of mild strain of virus to protect plant from infection by severe strain of the same virus. A research was initiated to employ cross protection approach for disease management to reduce the infection of ChiVMV. Initial exploration was conducted at chili peppers growing areas in Jambi, West Sumatera, and West Java to collect ChiVMV field isolates, whereas ChiVMV detection was conducted at Plant Virology Laboratorium, and transmission to chili peppers in Greenhouse Plant Protection Department, Bogor Agricultural Institute from February to July 2011. ChiVMV isolates were successfully collected and propagated in susceptible chili peppers line (Capsicum annuum L.) IPB C13. Based on percentage of symptom development, and disease severity of ChiVMV isolates can be differentiated into three groups, i.e. strong isolate (CKB), mild isolate (CKW), and weak isolates (KAR, SPR, IVAK, SKT, LGM, SKR, CGN, CSR, and PGL). Further characterization of promising ChiVMV weak isolates could use as an agent of cross protection candidates in controlling mottle disease caused by ChiVMV.
