. The next series of contributed chapters address difficulties in management of urban soils from physical and chemical standpoints. Chapter 7 covers the sealing of soils with an impermeable layer and assessing how this action affects urban soils. Soil

structure located within the seedcoat. The water gap can become permeable after exposure to temperature flux, drying, or scarification, thus allowing imbibition into an otherwise impermeable seed ( Baskin, 2003 ; Baskin and Baskin, 1998 ; Baskin et al

). In the case of R. glabra , physical seed dormancy is maintained by the water-impermeable endocarp tissue, in particular the outermost brachysclereid and internally proximal osteosclereid cell layers ( Li et al., 1999a , 1999c ). The water-impermeable

the type of cover material, type or absence of mulch, and the depth of snow cover ( Takeda et al., 2008 ). The black plastic used for treatments BPC and BPW was impermeable to moisture and air. The thermal blanket used in treatments TBC and TB was a

°C until use. Measurement of anthocyanin in apple. Ten to 20 fruits of ‘JPP35’, ‘Maypole’, and ‘Fuji’ were picked monthly from May to October. Half of the fruit on the tree was placed in light-impermeable two-layered double bags (Kobayashi Bag Mfg

fungi; water-impermeable “hard” seedcoats are common in many legumes, serve a protective function for the embryo, and have been the subject of several reviews ( Baskin, 2003 ; Kelly et al., 1992 ; Mohamed-Yasseen et al., 1994 ; Rolston, 1978

rooms in which the test chambers were placed controlled the temperature, light intensity, and relative humidity. The test chambers were made of inert materials (i.e., glass surfaces, stainless steel frame, and Teflon) that were impermeable to VOCs. The

succulent plants such as Agave have significant water reserves in the leaves resulting from their specialized morphology and the presence of an impermeable foliar cuticle ( Ramírez-Tobías et al., 2014 ), after 5 months of drought in a low water retention

through a semi-impermeable membrane, the rate of release can be altered by composition of the coating and coating thickness. Coated substrates can consist of urea alone or a complete fertilizer containing N, phosphorus, and potassium. Water vapor
