Juglans australis Juglans australis Juglans australis, the nogal criollo, is a species of plant in the Juglandaceae family. This large, fast-growing tree can grow to tall at altitudes of 0.5—1.5 km in the "Yungas" or Montane Cloud Forest of Argentina (including the provinces of Tucumán, Salta and Jujuy) and in Bolivia. It is more frost resistant than the Persian Walnut ("J. regia"). It is threatened by habitat loss. "J. australis" is a spreading deciduous tree, up to 25 m. wide which produces first quality lumber, with a straight trunk up to 6 m. tall and up to 5 dm. in diameter. The
Fruit tree pollination a pollinator tree. Working from an old Spanish variety, "Tuono", researchers in 2008 started making available new self-fertile varieties that more closely match the qualities of the popular "Nonpareil" almond—including varieties "Lone Star" and "Independence". While self-fertile trees do not require pollen from a second tree variety for fruit / nut set, they still depend upon insect pollination for good production. Almond growers with self-fertile almonds report excellent nut set with half (or less) the number of bees in the field. Like apples, pears are self-incompatible and need to attract insects in order to be pollinated and produce fruit. One
