was performed at the beginning of maturation and 15 days after the date of first defoliation
up to the height of bunches, and 6 leaves per cane were collected.
Relationships between acid deposition and crown defoliation
Cottonwood leaf beetle (Coleoptera: Chrysomelidae) defoliation
impact on Popolus growth and above-ground volume in a short-rotation woody crop plantation.
Water availability influenced stomatal conductance as a function of the defoliation
level, showing a very similar behavior in both evaluation periods (Figures 2A and B).
In tropical conditions, the defoliation
of banana 'Nanica' did not affect bunch mass and fruit size (VARGAS et al., 2009; GONZALEZ et al., 2012); however, in subtropical, there was a reduction in plants with less than 10 leaves (DANIELLS et al., 1994).
It was studied the frequency and intensity of defoliation
when heifers were kept exclusively in Italian ryegrass or in Italian ryegrass receiving supplement: a commercial extruded product with fat, in a proportion of 0.20% of body weight (fat) or corn grain in a proportion of 0.78% of body weight (corn).
was estimated counting the number of nodes in the main stem with and without leaves at the very moment and sampled in the date of each severity evaluation.
Formation of annual rings of the main coniferous tree species in Siberia after defoliation
of crown by Dendrolimus superans sibiricus Tschetv, Khvoinye Boreal'noi Zony 26(2): 161-172.
Data Analysis--We compared sample population levels for each of the three targeted species between sampling sites, months, and years, as well as the level of tamarisk defoliation
using One Way Analysis of Variance on Ranks.
The sub plot treatments were 0 % defoliation
), 25 % defoliation
and 50 % defoliation
