Changes in the mesocarp of Annona cherimola Mill. ‘Madeira’ during postharvest ripening

The Unusual Acid-Accumulating Behavior during Ripening of Cherimoya (Annona cherimola Mill.) is Linked to Changes in Transcription and Enzyme Activity Related to Citric and Malic Acid Metabolism.

Cherimoya (Annona cherimola Mill.) is a subtropical fruit characterized by a significant increase in organic acid levels during ripening, making it an interesting model for studying the relationship between acidity and fruit flavor. In this work, we focused on understanding the balance between the concentration of organic acids and the gene expression and activity of enzymes involved in the syn...

Lora Et Al., Bicellular and Tricellular Pollen in Annona Cherimola the Coexistence of Bicellular and Tricellular Pollen in Annona Cherimola Mill. (annonaceae): Implications for Pollen Evolution

Four alkaloids from Annona cherimola.

Four alkaloids, annocherine A, annocherine B, cherianoine, and romucosine H, along with one known alkaloid, artabonatine B, were isolated from the MeOH extract of the stems of Annona cherimola. Their structures were identified on the basis of both analysis of their spectral data and from chemical evidence.

Textural, biochemical and micro-structural changes in mesocarp tissue of imported avocado from Peru during ripening

Avocado (Persea americana Mill.) fruit is a valuable product and notorious for the difficulties encountered in determining quality. Typically the degree of ripeness of many climacteric fruits, such as avocado, is measured by assessing flesh firmness. The aim of the presented work was to elucidate the temporal and spatial changes in texture, biochemistry and micro-structure in different avocado ...

Respiration during Postharvest Development of Soursop Fruit, Annona muricata L.

Fruit of soursop, Annona muricata L., showed increased CO(2) production 2 days after harvest, preceding the respiratory increase that coincided with autocatalytic ethylene evolution and other ripening phenomena. Experiments to alter gas exchange patterns of postharvest fruit parts and tissue cylinders had little success.The respiratory quotient of tissue discs was near unity throughout developm...
