The muscadine grape is native to the southeastern United States and was the first native grape species to be cultivated in North America. The natural range of muscadine grapes extends from Delaware to central Florida and occurs in all states along the Gulf Coast to east Texas. It also extends northward along the Mississippi River to Missouri. Muscadine grapes will perform well throughout Florida, although performance is poor in calcareous soils or in soils with very poor drainage. Most scientists divide the Vitis genus into two subgenera: Euvitis (the European, Vitis vinifera L. grapes and the American bunch grapes, Vitis labrusca L.) and the Muscadania grapes (muscadine grapes). There are three species within the Muscadania subgenera (Vitis munsoniana, Vitis popenoei and Vitis rotundifolia). Euvitis and Muscadania have somatic chromosome numbers of 38 and 40, respectively. Vines do best in deep, fertile soils, and they can often be found in beside river beds.

Subtropical Peach Defoliation and Chill Hours

Jonathan Clavijo-Herrera and Ali Sarkhosh

Proper foliage management is a key factor in having a healthy peach orchard and producing high-quality fruit. However, this is not an easy task for Florida growers. The warm and humid climate throughout Florida’s growing season makes it difficult to keep peach leaf rust and bacterial spot under control, which could cause premature defoliation. On the other hand, leaves tend to stay attached to the tree well into late fall, when they should start senescing and dropping to allow sufficient accumulation of chilling, a process required for buds to break the dormant status and bloom in the next season. Understanding dormancy and preparing trees for this stage is critical in subtropical peach orchards. In this publication, we will discuss peach defoliation practices for peach trees growing under the subtropical climate of Florida to provide information to county and state Extension faculty, growers, and homeowners interested in peach production in Florida.

Alleviating Astringency in Persimmon Fruit for Enhanced Palatability and Consumer Acceptability

Ali Sarkhosh, Fariborz Habibi, and Jeffrey K. Brecht

Persimmon fruits are classified as astringent or non-astringent, depending on the level of astringency the unripe or partially ripe fruit exhibit at the time of harvest. Astringency in persimmon fruit is a sensation caused by tannins present in the flesh that can make the mouth feel dry, cause puckering, numb the tongue, and constrict the throat. Sometimes, it may also impart a bitter taste. The astringency decreases as the fruit ripen until it is no longer present in fully ripe fruit. While consumers typically prefer non-astringent varieties, the cultivation of astringent varieties notably remains common. The purpose of this publication is to introduce consumers, growers, Extension agents, and specialists to postharvest methods for reducing astringency in unripe persimmons, making them more palatable and acceptable for consumption.
