Traits in Avocado Efficient root systems increase the use of resources and improve productivity of cultivated plants. Propagation techniques can influence the root architecture of fruit crops. Fassio et al. (p. 63) investigated the effects of current

-deficient plants have greater root dry weight than plants grown with sufficient P ( Vance et al., 2003 ). These increases in root dry weight are typically reflected in changes in root architecture as well. Most plants such as Arabidopsis thaliana (L.) Heynh

observed differences between these results may be due to differences in the planting sites ( Campbell et al., 2006 ) or the dimensions of the AP containers ( Mariotti et al., 2015 ). The preceding studies have primarily focused on the root architecture and

Bloom (1990) showed no clear relationship between tomato root distribution and soil N availability. Root architecture often changes in response to availability and distribution of inorganic nutrients in the soil ( Lopez-Bucio et al., 2003 ). High levels
