various ratios to irrigation water to create various salinity levels. Like greenhouse container studies, salt accumulation in the field varied among beds and locations within the same bed as a result of differences in water use of the plants and
accumulation might be determined primarily by the differences in accumulated biomass rather than the nutrient concentrations in plant tissues. Significant differences were also observed among rootstocks with regard to accumulations of K and Ca. Leonardi and
used to analyze significant differences among bifenthrin rates in each inoculum treatment, and differences between mycorrhizal and nonmycorhizal plants in each bifenthrin rate were analyzed with the Student's t test. The percentages of mycorrhizal
aboveground parts plus the crown), whereas in plants fertilized with 50 and 100 kg·ha −1 N, the ratio averaged 0.61 and 0.48 g·g −1 , respectively. By contrast, the second year, the ratio was similar among treatments, averaging 0.34 to 0.39 g·g −1 at fruit
the challenge of combining various agronomic traits, such as high yield, quality, and resistance to abiotic and biotic stress, in the same genotype. Grafting, the union of two plant parts—namely, a rootstock (base of the union to provide the root

measurements were taken between 0900 and 1200 hr . The same measurements were repeated daily on the same leaf (premarked) of the same plants. To characterize the differences in photosynthetic characteristics among the clones, light curves were obtained by
