Mechanical Thinning of Apricot Fruitlets

Chemical Engineering Transactions, 2017
Apricot trees usually bear more fruits than they can adequately support. Crop load adjustment through fruit thinning is a routine practice adopted by fruit growers to obtain a marketable product. Manual thinning, although effective, is a labor-intense and expensive operation, accounting for over 30% of the production costs; chemical thinning, on the ...

Thinning effects on growth and occurrence of rotting in aspen stands

Journal of Forest Science, 2023
Poplar species such as aspen (Populus tremula L.) play a very important role in the forest formation process not only in Eastern European regions. Unfortunately, such aspen stands are often severely affected by fungal diseases, causing mainly core rot ...

Quantum mechanics on thin cylinders [PDF]

Physical Review B, 1993
We discuss the quantum mechanics of particles of arbitrary statistics on an infinite cylinder with and without a magnetic field perpendicular to the surface. In the presence of a magnetic field, the translational symmetry along the cylinder is broken down to a discrete one by the Aharonov-Bohm effect.

Influence of Mechanical Flower Thinning on Fruit Set and Quality of ‘Arisoo’ and ‘Fuji’ Apples

International Journal of Plant Biology, 2023
This study aimed to identify the efficiency of mechanical flower thinning (MFT) and its influence on apple fruit quality. In the first experiment, ‘Arisoo’ apple flowers were subjected to MFT with one hundred sixty-two (half) and three hundred twenty ...

Statistical Mechanics of Thin Spherical Shells [PDF]

Physical Review X, 2017
We explore how thermal fluctuations affect the mechanics of thin amorphous spherical shells. In flat membranes with a shear modulus, thermal fluctuations increase the bending rigidity and reduce the in-plane elastic moduli in a scale-dependent fashion. This is still true for spherical shells. However, the additional coupling between the shell curvature,

Mechanical Thinning of Mandarins with a Branch Shaker

HortTechnology, 2020
Thinning is the process of removing some flowers or fruit to increase fruit size at harvest. In the Valencia region of Spain, the thinning operation for citrus fruit (Citreae) is performed for some mandarin varieties.

Targeted grazing and mechanical thinning enhance forest stand resilience under a narrow range of wildfire scenarios

Ecosphere, 2022
Increasing wildfire activity has spurred ecological resilience‐based management that aims to reduce the vulnerability of forest stands to wildfire by reducing the probability of crown fire.

Managing Crop Load in European Pear (Pyrus communis L.)—A Review

Agriculture, 2021
Reducing levels of fruit set is often desirable in many European pear (Pyrus communis L.) cultivars. With a negative linear relationship between crop load and fruit size, crop load management early in the season minimises wastage of tree carbohydrate ...

Geometry and mechanics of thin growing bilayers [PDF]

Soft Matter, 2016
We investigate how thin sheets of arbitrary shapes morph under the isotropic in-plane expansion of their top surface, which may represent several stimuli such as nonuniform heating, local swelling and differential growth. Inspired by geometry, an analytical model is presented that rationalizes how the shape of the disk influences morphing, from the ...

Alternative Approaches to Chemical Thinning for Regulating Crop Load and Alternate Bearing in Apple

Agronomy, 2022
In the past, chemical thinning dominated in fruit orchards. This paper for the special issue outlines alternatives to chemical thinning for crop load management (CLM) and its effect on fruit size, firmness, sugar, starch, and weight, indicating ripeness ...
