When the university was named as Universiti Putra Malaysia (UPM) in 1997, the Library became the Universiti Putra Malaysia Library. Plants are susceptible to such localized calcium deficiencies in low or non-transpiring tissues because calcium is not transported in the phloem. Zinc deficiency is characterized by formation of small leaves wherein the leaf size is reduced to 50%. The effects of calcium deficiency on the appearance of ``glassiness'' or ``watercore'' and texture evolution in cantaloupe muskmelon (Cucumis mélo L.) and on polygalacturonase (PG) and b-galactosidase activities and their relation to ethylene production were studied. Zinc deficiency is mainly a problem in alkaline (high pH) sandy soils that are low in organic matter. Hence, the effect is known as “calcium induced iron chlorosis”. Often systems are complicated by more than one nutrient deficiency. The deficiency is common in soils with high calcium content. Specifically, maintenance of relatively high calcium concentrations in fruit tissue results in a slower rate of ripening, as seen in lower respiration rates, reduced ethylene production, and slower softening of fruit flesh. You may or may not experience symptoms if your blood calcium levels are low. deficiency or an excess of a mineral element. Ultimately only a full knowledge of the environmental conditions which cause the disorder, or the use of resistant cultivars, will totally prevent post-harvest losses from occuring.
