In a split-root system, growth characteristics and boron translocation were investigated in tomato plants in culture solutions with different B levels. Slioght B toxicity was associated with 324 umol B per litre (= 3.5 mg/litre) in the solution, while 3240 umol (= 35 mg/litre) prodiced clear symptoms. B deficiency was only observed when B was omitted from both halves of the system. A boron level of 3240 umol reduced weight of tops and roots in proportion to the parts, one or both, to which it was applied . Weight of tops, but not roots was reduced when boron was omitted from both parts of the system. There were no significant differences in growth between plants which received 32 umol B per litre in one part of the system, in combination with 0,32 of 324 umol B in the other part. B content were higher in the leaves of the side of the plant corresponding to the roots growing under high-B conditions. B content of leaves on the low-B side increased when the concentration in the high-B side was increased. This indicates a lateral movement of B. Roots which received no B in either side of the system absorved less nutrients, especially phosphate and potassium. |
