Abstract

Indonesia as a rich biodiversity country has many superior fruit plant germplasms such as sweet star fruit or carambola (Averrhoa carambola L.). Some varieties of carambola which collected at the Germplasm Garden of Research Center for Biotechnology-LIPI have been used for parent trees of fruit plant production. Therefore, they have to be characterized both phenotypically and genetically. The objective of the study was to analyze the relationship between eight varieties of carambola i.e. Malaysia, Penang, Rawasari, Bangkok, Sembiring, Dewabaru, Demak and Dewimurni at the germplasm garden based on phenotypic and genetic characters. Phenotypic characters were observed directly in the field, whereas genetic characters were observed with RAPD markers using 10 primers. Phylogenetic analysis was done using NT-SYS software showed that there were three clusters of carambola varieties. Meanwhile, Malaysia and Penang varieties have closed relationships (96%) compared with the other varieties. The result of the study would be dedicated to updating and completing the existing fruit plant collection database of Plants Germplasm Garden.

Abstract

Kemunduran benih merupakan suatu peristiwa yang pasti terjadi. Penanaman padi lokal oleh petani umumnya menggunakan benih yang berasal dari sisa hasil panen sebelumnya dan telah melewati tahap penyimpanan sebelum ditanam kembali. Penelitian ini bertujuan untuk mengetahui materi invigorasi hydropriming yang optimal dalam meningkatkan mutu fisiologis beberapa varietas padi lokal Jambi. Perlakuan diterapkan pada rancangan acak lengkap faktorial dengan 3 ulangan. Faktor 1 adalah varietas padi: Padi karya, Kuning Betung, Kuning Kerinci dan Gadis Jambi. Faktor 2 adalah invigorasi yang terdiri atas: kontrol (aquadest), larutan bawang merah dan larutan air kelapa muda. Sebanyak 30 butir benih untuk setiap satuan percobaan direndam selama 24 jam. Benih ditanam pada media kertas saring lembab dengan metode uji di atas kertas. Hasil penelitian menunjukkan bahwa tidak ada interaksi nyata antara varietas dan invigorasi terhadap perkecambahan benih padi lokal yang diuji. Perlakuan invigorasi menggunakan air kelapa nyata berpengaruh pada panjang akar, panjang plumula, panjang kecambah normal dan indeks vigor padi lokal. Varietas Kuning Betung memberikan tanggapan terbaik terhadap invigorasi. Perlakuan invigorasi merupakan upaya untuk memperbaiki performa benih sehingga mengurangi resiko kegagalan di lapangan, diharapkan berimplikasi terhadap peningkatan produksi padi.

Abstract

Response of six chili varieties to anthracnose disease caused by Colletotrichum acutatum and C. gloeosporioides. Chili is one of the horticultural commodities with high economic value. Chili production is constrained by anthracnose diseases. Losses due to anthracnose can reduce the fruits quality and yields lose. This study aims to determine the resistance of several chili varieties to anthracnose. Genetic material was used six varieties of chili. Ripe chilies were inoculated with two types of Colletotrichum isolates, i.e. C. acutatum and C. gleosporides. The experiment was arranged in a factorial randomized block design with three replications. The first factor were chili varieties: Laris, SSP, Habanero, Cibinong, Ekasari, and Kopay. The second factor was two types of fungal isolates. Observations were made on the incidence and severity of disease due to anthracnose. The results showed that both fungal isolates were effective in causing anthracnose disease in chilies. Habanero was very susceptible to anthracnose. Laris and Ekasari were moderately resistant to anthracnose diseases. These findings are important to develop new Capsicum cultivars that are more adaptive to anthracnose disease.
