| Abstract/Contents: | "Root hairs are a major site of water and mineral absorption. The objective of this work was to determine the contribution of root hairs to total root length both at the inter- and intraspecies levels, among eight warm-season turfgrasses. The turfgrasses were grown under glasshouse conditions in PVC columns (5 cm diam, 122 cm long) which housed flexible plastic tubing, containing washed sand. Pre-rooted propagules were planted, provided nonlimiting soil moisture via automatic drip irrigation, fertilized weekly, and grown for 133 d. At harvest, the intact root system was separated from the soil core by washing with water and length of all adventitious roots were measured. The root system was subsampled for determinations of number and length of primary and secondary branch roots and for microscopic analysis of length, ranging from 93% for 'Texturf 10' bermudagrass (Cynodon dactylon) to 20% for 'Emerald' zoysiagrass (Zoysia japonica x Z. tennuifolia); also there were vast differences among cultivars of bahiagrass (Paspalum notatum), and among species and cultivars of bermudagrass and zoysiagrass. Total root lengths (root hairs included) also were significantly different at the inter- and intraspecies levels. This was related to both rooting and branching patterns and root hair density and length." |
