“…These differences could suggest a differential response and requirement for B by these two species. The data are in agreement (although the magnitude is different) with other reports for other plant species (22,27,32,36). These results could indirectly indicate an effect of B on membrane integrity as suggested for its role by Pilbeam and Kirkby (30).…”

“…Some reports have shown that increasing the B level in the media results in an increase in the calcium (Ca) content of tissues (22,27,36), while some others have found a decrease in the Ca content of tissues when the plant is B deficient (7,32). Still another report indicated no change in several elements, including Ca, at different levels of B in the media (10).…”

Date palm (Phoenix dactylifera L. cv Khedhri) and sorghum (sorghum Sudan grass hybrid cv sugar Graze 11) plants were grown in vermiculite in a controlled environment and watered with a nutrient solution containing eight different concentrations of boron (B) (0 to 500 ppm), six months for date palm and four weeks for sorghum. The chlorophyll (Chl) content of the seedlings increased significantly with low concentrations of B for both date palm and sorghum, but no further significant increases were observed at higher concentrations. Generally, there was a positive correlation between B and calcium (Ca) content in the tissues of both seedlings when B concentrations were increased in the media. A negative correlation was found between B concentration in the media and the tissue content of phenolic compounds and the activity of some enzymes, such as polyphenol oxidase, IAA-oxidase and phenylalanine ammonia-lyase in the tissue, while there was a positive correlation in the case of peroxidase. Ribonucleic acid (RNA) increased significantly in date palm with the increase of B in the medium, but for sorghum, the increase occurred at 10-100 ppm and decreased at 300 and 500 ppm B in the media.

SUMMARYBoron deficiency reduced absorption of phosphate in whole plants and root segments of Vicia faba. The overall phosphate metabolism of the whole root was unaffected but both the equilibrium pattern and initial rates of esterification were altered in the root tip region. The equilibrium ratio of inorganic phosphate to organic phosphate was not affected. Addition of boron at 10 / xM to the deficient plants for 1-2 h prior to absorption reversed the effects of boron deficiency in both absorption and metabolism of phosphate although it did not stimulate the initial rates of esterification of the absorbed phosphate.

Inadequate supplies of K and B have been associated with short life and low yield of alfalfa in the eastern United States. For this reason, studies of the influence of these two elements on the behavior of this plant are of special interest. This paper is concerned with such studies.Literature review HUNTER, TOTH, and BEAR (9) concluded that when the K content of alfalfa falls below 1 per cent., its Ca exceeds 2 per cent., or its Ca-K equivalent ratio is greater than four, yields are greatly depressed. It was also shown that although the content of the individual cations may vary widely, cation-equivalent summation values tend to be constant under standardized environmental conditions. Such cation interrelationships in plants have received considerable attention (7,19,28).Other work from this station (29) has shown that plants having high cation-equivalent values also tend to have high mineral anion-equivalent values. When alfalfa plants were grown under uniform environmental conditions, except as to the nutrient supply, cation-anion equivalent ratios were essentially constant. This applied, notwithstanding variations in the relative amounts of the different cations in the nutrient medium and regardless of the season of the year. Other workers have noted this phenomenon (17,23).Extensive data on K-B and Ca-B relationships in plants are highly contradictory (5,18,24
