University of Georgia has a breeding program at the Tifton campus working to select pecan varieties adapted to subtropical southeastern U.S. growing conditions.. The husks are produced from the exocarp tissue of the flower, while the part known as the nut develops from the endocarp and contains the seed. Juglandaceae are represented worldwide by between seven and 10 extant genera and more than 60 species. Read on to find out the Top 10 Fun Facts about Pecans. Pecan Planting Guide: Location and Preparation. In other words, its female flowers should be receptive when its companion is producing pollen, and vice versa. Pecan wood is often utilized for the manufacturing of furniture, paneling and flooring. , Choosing cultivars can be a complex practice, based on the Alternate Bearing Index (ABI) and their period of pollinating.  Commercial growers are most concerned with the ABI, which describes a cultivar's likelihood to bear on alternating years (index of 1.0 signifies highest likelihood of bearing little to nothing every other year). Compounds found within alkaline soil prevent the zinc from being soluble, and so, in this case, it is better to use a zinc foliar spray. Pecans are a major ingredient in American praline candy.
