Abstract: In order to understand the effect of feijoa cutting quality on seedling plants, different diameter cutting of cultivar Unique was used as materials for cutting propagation. The results showed that cutting diameter has a remarkable influence on the rooting rate, rooting traits (sum of adventitious roots and average length of roots), germination rate and growth quantity of shoot of Feijoa sellowiana; the rooting rate, traits, germination rate and growth quantity of shoot obtained from using the diameter from 2.5-3.0 mm are significantly greater than those using the diameter 2.0-2.5 and 1.5-2.0 mm; thus the cutting slips of >3.0 mm in diameter are the best choice for seedling growth.
