| الوصف: | SummaryTomato fruit walls often possess tiny yellowish spots around the calyx and shoulders of the fruit, so-called gold speckles. In some cases these become very numerous and lead to down-grading of the fruit. In such fruit crystal sand is present in separate cells and groups of cells in the outermost parenchymatous tissue layers of the mesocarp. This crystal sand causes the gold speckles. Also raphid crystals occur in great quantities in the pulp of those tomatoes which display numerous gold speckles in the wall. Druse crystals are absent. Both crystal sand and raphid crystals proved to be organic calcium salts, probably calcium oxalate. Silicon was associated with the crystal sand containing cells of the mesocarp, either as very small silica grains in the cell or randomly distributed in the cell wall as in normal cells. The long raphid crystals may perforate neighbouring parenchyma cells during picking and transporting of the fruit and hence limit its storage life-time. Nutrient substances used in subs... |
