(1989) attempted to validate Eq. [1] . They found that linear relationships between measured and predicted properties of bark:sand and bark:perlite substrates were good for bulk density (D b ) but mixed or poor for other parameters such as total

Research in agricultural soils has shown benefits of incorporating organic amendments in improving soil physical properties, including reduced bulk density ( Foley and Cooperband, 2002 ; Tester, 1990 ), increased infiltration rate ( Cox et al

phytotoxic levels of one more mineral nutrients. Other materials evaluated as potential alternatives to perlite are either too expensive or have unacceptably high bulk densities (e.g., calcined clay aggregates, gravel), which resulted in unacceptably high

for resistance can also be used to pyramid resistance genes into commercially acceptable cultivars. Amplified fragment length polymorphism (AFLP) markers combined with bulk segregant analysis (BSA) is a powerful technique for identifying markers linked

backcross populations developed from a cross of a rust-resistant and rust-susceptible asparagus bean cultivars for resistance to rust, determine the inheritance of rust resistance, identify an AFLP maker linked to this resistance using bulk segregant

with native soil and vice versa, pore spaces in both soil sources can become compromised. Macropores in sand can be filled by finer soil particles, reducing porosity, increasing bulk density, and reducing necessary water movement through the profile

amounts of potential mycorrhizal propagules originated in vivo and in vitro, and inoculation treatments were as follows. In vivo inoculation treatments consisted of: 1) bulk inoculum: 2 mL of substrate (with ≈50% pore space) from the host plant rhizosphere

the second round of evaluation. PM severity on each plant was rated as described above on 3, 11, 19, and 27 Jan. 2012. The eight ratings were averaged by progeny to obtain the PM resistance phenotyping data set PM-0112. Bulked segregant analysis. On
