Therefore, it is imperative that you consult a pecan variety pollination chart (learn more at when designing a pecan orchard to ensure there will be adequate pollination. Pecan trees are not precocious, and it requires at least 5–10 years after a cross is made until the resultant hybrid can be evaluated (Madden 1968). All the varieties listed beneath it in regular font should pollinate it with the best pollinators for each variety listed in italics. Pecan trees bloom and shed pollen at separate times, making pecan tree pollination different from fruit trees. Self-pollination can reduce nut quality and greatly reduce crop yield by as much as 75 percent. In addition, one open-pollinated seedling of 'Mahan', 'Maramec', has been released.

It requires a protogynous, or Type II, tree to pollinate it. It is recommended that a grower should plant a Desirable Pecan tree along side. For most horticultural plants to successfully produce a crop, viable pollen must be present when the female flowers are receptive for pollination. A common question asked by homeowners is “Can I plant just one pecan tree in my yard or pasture?” To sufficiently answer this question, we must first discuss the dichogamy of a pecan tree and how it affects pollination. Figure 2. It is a first class pecan with a richly flavored kernel. The resulting seed was germinated and grew into a tree that was later named Mohawk in 1965. For example, the addition of 1.25 g/m2 of PBZ inhibits pecan branch growth and stimulates short bearing branches, which promotes fruit yield. ESTIMATED CHILLING REQUIREMENTS (BELOW 45 DEGREES): 400 to 500 hours.Cold hardy down to 15° POLLINATION: Needs a second chinquapin tree for pollination. Chestnutt in Kosclusko, Attala County, Miss.

Jan 13, 2017 - The biggest pecan grown. Explore. You can find some trees that mature the male flowers first followed by the maturing female flower, with this sequence being a Type I or protandrous flowering. Most fruit trees have flowers that are considered complete, with each flower having a pistil (female) and stamen (male) reproductive structures. We are now taking reservations for winter delivery. High humidity delays pollen dehiscence and extends the period of nutlet receptivity, according to research published in proceedings of the National Pecan Association in 1929. Enter your e-mail for growing tips, advice and Sustained high winds coupled with low humidity tend to shorten the period of effective pollination, both by accelerating pollen dehiscence and by shortening the period of nutlet receptivity. Research indicates that effective pollination may decrease at distances greater than 150 feet from a pollen source, so you must have pollinator trees no further than every fourth row. Home and Garden. Common Type I or protandrous pecan varieties: Common Type II or protogynous pecan varieties include: However, it is not as simple as planting a random combination of protandrous and protogynous pecan varieties. If male pollen release does not overlap nutlet receptivity then the tree has complete dichogamy, but if the timing of pollen release does overlap nutlet receptivity then the tree has incomplete dichogamy. If you look at Figure 3, you can easily see that while Kanza (Type II) is a good match for Caddo (Type I), use of another Type II pecan such as Forkert would be a poor choice as a pollinator for Kanza or Caddo. Mahan pecan trees come from a chance seedling planted in 1910. Protogynous cultivars typically have long, thin catkins, while protandrous cultivars typically have catkins which are shorter and of greater diameter (Figure 2).

When planting pecan trees, they need to be spaced 40 to 60 feet apart in orchard plantings and no closer than 40 feet for home plantings. We now have six years of observations on this selection, and four years of data on fruiting, as we topworked some large trees which had some fruit two years later on this precocious cultivar. The canopy of young ‘Stuart’ trees is among the narrowest of all pecan cultivars. 37 nuts/lb. Appropriate cultivation practices that can be implemented to enhance fruit yield of cultivars Mahan and Western include soil-applied paclobutrazol (PBZ) at certain concentrations, pinching, and supplementary pollination. In an orchard situation, having a few odd trees as pollinators will greatly improve yield. Female nut clusters (nutlets) occur on current season growth, while male catkins (pendulous flower spikes) grow on previous season growth. Caddo: Has one of the highest yield potentials of all pecan trees. It has become a replacement for Desirable in new orchards because of the better scab resistance. Garden Types. We found that pecan cultivar Mahan gives a higher yield and nut quality than cultivar Western. They have both female and male blooms on a single tree, but the male and female flowers open at different times which makes the spreading of pollen a little difficult. Trees are not precocious. A very versatile fruit tree that is excellent for home yards. A pecan tree has both male flowers (pendant catkins), and female flowers (erect spikes), on the same tree. Pecan Trees. At one time, the Success cultivar was the most popular cultivar grown in the Southeastern US. However, pecans are different because they have separate male and female flowers on the same tree. Search.
