Effects of boron deficiency on the elongation of root tips of tomato and sunflower seedlings were investigated and the morphological responses of root tips were discussed. The primary effect of boron deficiency was the rapid cessation of root elongation followed by browning and some morphological changes in the root tips, such as abnormal enlargement and dense appearance of lateral roots. Root elongation was extremely inhibited within 3 hr after the plants were placed in boron-free media and the lack of boron in the nutrient solution for 72 hr or more caused the root tips to suffer necrosis. The rapid cessation of root elongation was characteristic in boron deficiency and calcium deficiency among several essential element deficiencies which were tested. Differences between boron and calcium deficiency symptoms were discussed in relation to the morphological characteristics of the root tips.
