Physiological age of stem cutting showed significant difference among the seedling growth variables. However,
the genotypes, and its interaction with stem cutting did not affect on all growth seedling variables and their field
survival at p = 0.05 (Table 1). It mean that the genetic base of Jatropha curcas genotype from West Nusa
Tenggara was quite small, especially for seedling and early vegetative growth characteristics. Therefore, further
discussion focused only on the effect of difference of physiological ages stem cutting
