accurately reflects the rate; however, different media volumes may significantly impact the contribution by microbes. To test this assumption, we assessed the VOC removal efficiency of plants as rate/aboveground volume to media volume ratio and rate/LA to
between DLI and carbohydrate accumlation under LEDs with different R:B ratios when white LEDs were used as base lighting source, and there were few bases for the spectrum design of relatively broad and wide LEDs for lettuce cultivation. In addition, few
This paper compares the use of slope-based and ratio-based approaches to evaluate CO 2 assimilation. Mathematical principles inherent in any ratio-based efficiency assessment ( Atchley et al., 1976 ; Packard and Boardman, 1988 ; Pearson, 1897

Systematic research with kaolin as a particle film technology began in 1970 ( Abou-khaled et al., 1970 ). This report stimulated research that contributed to the formulation of Surround WP, a commercially available kaolin-based powder. This

Mountains. Based on a great deal of investigations of the ungrafted seedlings, hundreds of superior individuals were collected for further identification for their use in the red-fleshed kiwifruit breeding program. Eight red-fleshed accessions (AB, AF, H, K
