“…164 Boron deficiency inhibits growth, kills growing meristems, inhibits flower development, and causes low fruit and seed set, male sterility, seed formation of damaged embryos and malformed fruit. 171,172 Boron is commonly thought to be absorbed from the soil solution by roots mainly as undissociated boric acid. Boron foliar spray application has been proved beneficial in case of B deficiency.…”

“…For commercial fruit production, fruits produced under controlled greenhouse conditions, do not seem to be the best index of the B status of the plant. In apple, however, Askew (1) found that the fruit rather than the leaves is a more sensitive index of B status of the tree.…”

A sand culture greenhouse experiment was conducted with papaya, Carica papaya L., variety Blue Solo, to determine the effects of four levels of Bin the nutrient solution (0.01, 0.05, 0.1 (control), and 1.5 p/m) on growth, fruiting and mineral content. B deficiency and B excess symptoms are described for leaves, petioles, central stems, and fruit. Mineral contents of leaves, petioles, and fruits are presented and discussed. Fruits receiving 0.05 p/m B in the nutrient solution were preferred. The critical level of B appears to be about 20 p/m in the petioles and leaves, whereas excess B occurred at about 70 and 300 p/m, respectively, for petioles and leaves. Quality components of the fruits are based on taste panel evaluation.

“…According to Burrell a greater deficiency of boron is required to produce rosetting and die-back than to induce internal cork in the fruit. Many investigators have demonstrated that this disease can be controlled b}^the application of borax or boric acid to the soil (see, e.g., Askew, Chittenden and Thomson, 1936). Internal cork does not appear so far to have been recorded in Britain.…”

In the year 1699 Woodward published the results of experiments in which cuttings of plants were grown, not in soil, but in rain water. More than a century and a half later Julius Sachs (1860) and W. Knop (1860) independently developed this method of water culture by growing plants of several different species in a dilute aqueous solution of various salts. In this way the materials available for absorption by the roots of the growing plants were controlled, and Sachs and Knop concluded from their experiments that so long as the culture solution contained salts involving the elements nitrogen, sulphur, phosphorus, potassium, calcium, magnesium and iron, a perfectly healthy plant would result. The elements occur in soil as constituents of compounds present in, or derived from, the minerals of the underlying rock, and are therefore generally known as mineral nutrients. Experiments of this kind have been repeatedly carried out by subsequent investigators and many formulae for water-culture solutions have been used and recommended. The water-culture method has also been extensively used for research in plant nutrition. Some of the best known and most widely used waterculture solutions are those of Sachs and Knop themselves and the later ones of Pfeffer and Von der Crone. Plants of a great number of species have been successfully grown in water culture, and in recent years the method has been advocated, perhaps too optimistically (cf. Hoagland and Arnon, 1938), as a means of cultivating certain crop plants on a commercial or semicommercial scale. The compositions of some of the best known and most widely used water cultures are given below. Sachs's nutrient solution Potassium nitrate l'Og. Sodium chloride 0-5 g. Calcium sulphate 0-5 g. Magnesium sulphate 0-5 g.
