; Spayd et al., 1990 ). Similarly, the relative humidity (RH) for storage recommended in these handbooks ranges from 80% to 95%. These recommendations are based on a limited number of studies, most being conducted over 60 years ago ( Levine et al., 1941

Boron moves passively into plants from the roots to the shoots through the transpiration stream through the xylem ( Jones, 1991 ; Kochian, 1991 ; Kohl and Oertli, 1961 ; Raven, 1980 ). Relative humidity can be a major factor influencing the rate

activity and inhibit plant growth ( Vanthoor et al., 2011 ). Excessively high humidity in a greenhouse reduces plant transpiration and causes flower rot ( Huang et al., 2011 ) and, over the long term, reduces fruit quality ( Choi et al., 1997 ). Control of
