tall and 0.45 m in average width, generally less than half (0.061 m 3 ) the canopy volume of ligustrum or viburnum (0.136 m 3 ). Objectives of this research were to quantify daily ET A of Indian hawthorn from transplanted rooted cutting to market size

grapefruit on Troyer citrange [ P. trifoliata (L.) Raf. × c . sinensis (L.) Osbeck] rootstock with a severe strain of exocortis reduced trunk diameter and canopy volume ( Timmer, 1978 ). Viroid indexing studies on Etrog citron showed symptoms resembling

( Byers et al., 2005 ; Marini, 2000 ; Stover et al., 2001 ). Several approaches have been used to measure crop load, including fruit number normalized by tree size based on trunk cross-sectional area (TCA; cm 2 ), tree size based on canopy volume (m 3

long-term context of greater than 4 years, that moderate-width hedge-type pruning treatments might eventually prove superior to nonpruned trees as tree crowding gradually reduces canopy volume over the years. Results indicate that mechanized hedgerow

placed at a height of 1.5 m on both sides of each replicate tree. Leaf number in the frame was used to estimate total number of leaves per tree based on canopy volume measurements. To determine leaf area, a 25-leaf subsample from each replicate tree was

. Trees were visually similar in morphological features such as canopy volume and trunk diameter. Table 1. Soil characteristics of the studied persian walnut orchard located in Shahmirzad, Iran (lat. 52°21′N, long. 35°41′W), before Zn and B treatments were

significant year × irrigation, year × cultivar, and year × soil management interactions for yields and fruit quality measurements ( Tables 3 to 5 ). Greater tree size (and hence canopy volume) was the likely reason for greater yield for HFI trees relative to

adjacent four plants for each replication. The two widths of each plant were multiplied to estimate the two-dimensional PCA (i.e., canopy footprint). When PCA was multiplied by the average height, canopy volume, or growth index, was estimated ( Henny et al

uniformity in height and canopy volume then measured for trunk cross sectional area (TCSA) after bloom was complete. Ten trees were selected to be within 10% of the mean TCSA for a subset of 100 trees measured within the orchard. These trees were thinned to a

second assumption of VRF is that small immature resets should get less fertilizer than mature trees. Because canopy volume is related to tree height and fruit yield, fertilizer rates can be adjusted based on tree height that is measured “on-the-go” by
