SKRIPSI PENGARUH JUMLAH BUKU DAN KADAR IBA TERHADAP PERTUMBUHAN TURUS JERUK KEPROK ( Citrus nobilis Lour )
ABSTRACT
The research concerning the effect of node number and IBA concentrations on the growth of keprok (Citrus nobilis Lour) cuttings, was done in May 17, 1987 until September 6, 1987 in PT. HORTIMART UTAMA, Bawen, Semarang.
The research using factorial design (3x4) with basic design of Randomized Complete Block Design (RCBD) with three replications. The first factor is node number the second factor is IBA concentrations.
The conclucions of the research are:
1. Node number influence very significantly on number of rooted cuttings, number of roots, lenght of roots, lenght of shoots and fresh weight of roots. But no sig- nificant influence on number of alive cuttings and dry weight of roots and interaction all.
2. IBA concentrations influence very significantly on num- ber of callused cuttings, number of rooted cuttings, number of roots, lenght of roots and lenght of shoots.
3. Three node cuttings aktained the best growt.
4. IBA concentration 6.000 ppm produce the heighest num- ber of callused cuttings, number of rooted cuttings and number of roots. Where as 4.000 ppm concentration produce the longest root.
