Daftar Isi:
- The aims of the research were to determine index of Al saturation causing Al stress in chili and to identify chili genotypes tolerant to Al using root bioassay. The research was carried out at University Farm of IPB at Cikabayan from September 2005 to January 2006. The media was Ultisol from Gajrug (Lebak, Banten) in polybags. Twenty genotypes of chili were tested at different level of Al saturation (0.77, 15.92, 31.96, 60.85 and 83.48%) by adding lime also in different treatments (18.33, 13.75, 9.16, 4.58 and 0 g CaCO3/kg soil, respectively). The tolerance to aluminum was determined by relative root length (RRL) value, by comparing the root length at Al-stress condition to that without Al-stress condition. The screening results showed that 5 genotypes were potentially tolerant to Al (PBC 619, Jatilaba, Cilibangi 5, Jayapura and Marathon); 3 genotypes were moderate (Randu, Karo and PBC 473); and 12 genotypes were sensitive to Al (Cilibangi 3, PBC 549, Tit Bulat, Helm, Bengkulu, PBC 065, PBC 593, Tampar, Tit Super, Cilibangi 6, PBC 584 and Cilibangi 1).
