Vegetative Morphology of Fruit and Nut Crops HORT 319 - Temperate Fruit and Nut Production
The Tree HORT 319 - Temperate Fruit and Nut Production
Fruiting wood • Shoot type: long (bourse) vs. short (spurs) • Flower Bud Position: lateral Vs. terminal HORT 319 - Temperate Fruit and Nut Production
Spur branch • Short lateral branches in which the internodes are extremely short, bringing several leaves close together in any given year and potentially many leaf scars close together over several years. HORT 319 - Temperate Fruit and Nut Production
Flower Bud InitiationWhen does it occur?Why is this important? • Most initiate the summer before fruiting • Apple, pear • Peach, plum, cherry • Persimmon • Blackberry, blueberry • Some initiate same year as fruit • Fig, 2nd crop • Quince • Strawberries HORT 319 - Temperate Fruit and Nut Production
Bud types • Leaf versus flower bud • Simple, Mixed, & Compound • Simple buds HORT 319 - Temperate Fruit and Nut Production
Stem Morphology HORT 319 - Temperate Fruit and Nut Production
Bud types • Mixed Buds = contain floral and vegetative primordia • Compound Buds = formed by multiple buds HORT 319 - Temperate Fruit and Nut Production
Leaf Morphology HORT 319 - Temperate Fruit and Nut Production
Leaf Morphology HORT 319 - Temperate Fruit and Nut Production
Leaf MorphologyLeaf glands on Prunus HORT 319 - Temperate Fruit and Nut Production
Reproductive Type • Perfect or hermaphroditic • Peach, apple, blackberry HORT 319 - Temperate Fruit and Nut Production
Reproductive Type • Imperfect flowers - Heterogamous • Monoecious, pecan, walnut • Dioecious, kiwi, pistachio, persimmon HORT 319 - Temperate Fruit and Nut Production
Laboratory Procedure • Examine vegetative samples of fruit and nut crops • Answer questions on work sheets • Press samples for notebooks • Label with name & mount next week (8 pts) • Turn in worksheets to lab assistant for grading (17 pts) • Put fruit sensory evaluation data in notebook HORT 319 - Temperate Fruit and Nut Production
Proper terminology ID all fruit and nut samples Common and scientific Know fruiting habits When, type, position Why important? Reproductive types Perfect Vs. Imperfect Monoecious Vs. Dioecious Protogynous Vs. Protandrous Things to learn from this lab HORT 319 - Temperate Fruit and Nut Production
