Post-Bloom CPPU Application Is Effective at Improving Fruit Set and Suppressing Coloration but Ineffective at Increasing Fruit Size in Litchi

چکیده
This study aimed to provide a reference for the practical use of forchlorfenuron (CPPU) in improvement fruit set and quality (especially size) litchi (Litchi chinensis Sonn.). CPPU at 5 mg/L was sprayed clusters ‘Feizixiao’ 2, 4, 6 8 weeks after female bloom (WAFB) 2017 6, 8, 9 or 10 WAFB 2018, with spraying water as control. The treatments were all effective suppressing abscission, resulting higher retention harvest. Except treatment 2 WAFB, which caused stunted significantly reduced weight, had no significant influence on weight flesh (aril) although tended increase pericarp strongly suppressed coloration, such effects most WAFB.

Gibberellin Application at Pre-Bloom in Grapevines Down-Regulates the Expressions of VvIAA9 and VvARF7, Negative Regulators of Fruit Set Initiation, during Parthenocarpic Fruit Development
Fruit set is initiated only after fertilization and is tightly regulated primarily by gibberellins (GAs) and auxins. The application of either of these hormones induces parthenocarpy, fruit set without fertilization, but the molecular mechanism underlying this induction is poorly understood. In the present study, we have shown that the parthenocarpic fruits induced by GA application at pre-bloo...

In order to investigate the effects of putrescine on growth and development of olive fruits an experiment was conducted on Olea europaea ‘Fishomi Tokhme-Kabki’ trees in 2017 and 2018.The treatments included control (normal fruits and shotberries), normal fruits, shotberries, normal fruits with putrescine at 3 and 6 mM and shotberries with putrescine at 3 and 6 mM were sprayed on uniform bra...
متن کاملCultivar and fruit size influence bruise susceptibility and some physical properties of apple fruit
ABSTRACT- For most fruit types, including apples, bruising is the most common type of postharvest mechanical injury. Bruise susceptibility was investigated in 3 commercial cultivars (‘JazzTM’, ‘Granny Smith’ and ‘Fuji’) and among a range of 4 different fruit sizes (commercial counts of 135, 120, 100, and 88) in each cultivar. Bruising was carried out by dropping a uniform round steel ball (110g...
متن کاملChanges in phenolic compounds in Litchi (Litchi chinensis Sonn.) fruit during postharvest storage
Litchi (Litchi chinensis Sonn. cv. Huaizhi) fruit were stored at ambient temperature (20–25°C) for up to 7 days and at 4°C for up to 35 days for separation, purification and identification of individual phenolic compounds and investigation of their changes during postharvest storage. Results indicate that flavan-3-ol monomers and dimers were major phenolic compounds representing about 87.0% of ...
