Plant Growth Regulators
Ethylene is one of the hormones that control the growth of a tree. It promotes abscission of the leaves, inhibits shoot elongation, and delays lateral bud development. Ethylene is important in the transition of fruit from physiologically mature to ripe. Ethephon and retain are synthetic compounds that inhibit ethylene biosynthesis. These compounds help fruit hang on the tree longer, extending its storage life.
Gibberellins are a family of chemical compounds that regulate plant growth. There are 130 different gibberellins found in plants, fungi, and bacteria. Some are non-bioactive and act as precursors to bioactive GAs, while others are de-activated metabolites. Gibberellins regulate plant development and seed germination. The most commonly used plant growth regulators inhibit the natural hormones in plants.
However, there are some important differences among the three types of GAs. GA reduces flowering on heavy-fruit-load trees while PBZ promotes it in low-fruit-load trees. PBZ promotes flowering in low-fruit-load trees, while GA at 25 ppm reduces it on medium-to-low-fruit-load trees. The late blooming in heavy-fruit-load trees reduces yield because of their early flowering.
There are some fungicides and plant growth regulators available for controlling tree development. One of them is PBZ, a member of the triazole plant growth regulators, which inhibits gibberellin biosynthesis and results in compressed internodes. As the pbz reduces shoot and branch diameter, the fungicide reduces the production of gibberellins and phytol.
When you want to prune a tree to stop it from bearing fruit, you have to identify the problem. Pruning is a common treatment for diseased plants, but only if it’s done correctly. A good pruning plan will work with the natural growth habit of the plant, and develop a healthy primary structure. Pruning should be done in small increments, minimizing the overall amount of branches.
During the initial growing season, you should prune a flowering tree to remove any branches that are growing vertically from the main stem. It is very important to do this in order to maintain the shape of the tree, and to avoid crowding the center of the tree with congested, diseased wood. You should also prune to remove branches with fat buds, which are flower or fruit buds. These buds usually develop on pinkish branches, while greener wood is last year’s growth.
When pruning a tree to stop it bearing fruit, remember that a heavy load on the limbs can cause broken limbs and produce smaller, less-quality fruits. Even worse, it can result in 6 inches of space between each fruit. The tree needs airflow to be productive and produce the best fruit possible. Proper airflow is essential for the health and productivity of a fruit tree, and pruning will restore it to a manageable height.
Some common reasons a tree may stop bearing fruit are over-feeding, poor nutrition, and poor pollination. The following tips should help you determine the culprit. If the tree doesn’t flower, or produces only tiny, undeveloped fruits, it may be suffering from poor pollination. Insect activity may be at fault, too. In these cases, the tree should be pruned back to achieve the desired form.
The first cause is over-fruiting. A tree’s flower buds produce more fruit than it needs. This results in too many blossoms, which can break the branches. Excess fruit may also cause smaller fruit. Another cause is over-feeding, which means that more developing fruit are provided with nutrients than necessary. The solution to this problem is to thin out the fruits by hand every year. It’s a natural process that extends the process of June drop.
Besides the negative environmental effects, over-fertilizing is also bad for your wallet. Excess fertilizer can get into natural streams and groundwater. Fertilizing your fruit tree too often can mess with the ecosystem and your wallet. Over-feeding new fruit trees may actually prevent them from bearing fruit. Newly planted fruit trees don’t need the extra help from fertilizers. Their needs should be given some time to establish in the new environment.
Lack of Pollination
If you notice that a tree doesn’t produce fruit, it may be because it lacks pollination. Some fruit trees, such as peaches, nectarines, and apricots, are self-fertile but still need pollination to produce fruit. In this situation, bad weather or insects may deter pollinating insects and reduce the fruit set. To remedy this problem, plant different varieties of fruit that are compatible with each other.
In addition to lack of pollination, a tree may produce small fruit or be biennial. In this case, you should choose a tree with low branching. Fruits on dwarf trees, however, are often small. If your tree is heavily cropped, be sure to thin its branches to prevent the mature fruit from touching neighbours. If the tree is not pollinated, the crop may be weak or even diseased.
In some cases, the tree might be too old to produce fruit or be treated with an insecticide such as carbaryl during bloom. Some fruits, such as apples and pears, won’t bear fruit until their third or fifth year. In these cases, you can remove the fruit to encourage the tree to grow in the proper number of branches for future crop production. The tree might also be too young or have poor pollination.
Pollination relies on the activity of bees and other pollinators to transfer pollen from flower to flower. Fortunately, bee populations in rural areas are generally abundant, but late frosts can severely damage blossoms and early stages of fruit development. Also, low temperatures during the blooming season can hinder pollination. To increase your fruit tree’s odds of producing fruit, you can invest in commercial beekeeping services or hire a professional beekeeper to visit your trees.
If you want your tree to bear fruit, make sure to water it properly. If the soil around the base of the tree is too wet, then it is over-watered. Over-watering a tree will result in dothiorella canker or phytophthora canker collar rot. Remove the affected bark by scraping the trunk. You can also use a soil moisture meter to check the soil moisture.
You can prevent over-watering by applying organic amendments to the soil. Generally, you should repot the tree every two months or so. Organic amendments such as compost will improve the drainage of the soil. Once you have done this, you can water your tree more often. Over-watering can even prevent it from bearing fruit! Over-watering is just as bad as not enough watering!
In some cases, fruit trees can stop producing because they do not have enough blossoms. This can affect fruit formation next year. Insecticides can also cause problems. Fruit will appear on a pear tree only in the third to fifth year after planting. When this occurs, remove the fruit as soon as possible to allow the tree to develop the proper number of branches for future crops. If you do notice fruit on your tree, remove it promptly to ensure the best growth conditions.
While over-watering can prevent the tree from bearing fruit, it is equally harmful to the roots. Waterlogged soils rob the soil of its vital oxygen. This results in a severely damaged root system. Tree roots cannot continue to grow or absorb minerals from the soil, resulting in yellow leaves. Yellowing of the leaves begins on the lower portion of the tree. Trees with water-logged soils have lower-quality fruit. Their root systems are also more vulnerable to phytopathogen infections.
While the spring season can be an exciting time of year, it can also be a dangerous time for your trees. While new growth is more susceptible to frost damage, flowers and buds are vulnerable to damage. Protect your fruit trees by covering them with row covers or plastic. Ensure that the covers completely envelop the plants, reaching the ground. Frost damage to blueberries is particularly damaging. Frost can damage the delicate blossoms of rabbiteye blueberries. This results in undersized and misshapen fruit.
The amount of damage from frost may not be directly proportional to yield loss at the end of the season. The amount of damage will depend on the type of crop, as larger fruit requires only ten percent of the previous summer’s buds. If frost damage occurs at the bottom of the tree, it will be more severe there. But even if the bottom portion of the tree is untouched, it’s still possible to prevent loss.
The symptoms of frost damage can take several hours to appear. However, the affected area will look black or brown when warm. This is the best time to evaluate the extent of the damage. Ideally, you should assess the affected areas using shoots that have flower buds. A good light source and magnification are recommended to make a detailed diagnosis. If the tree has already suffered frost damage, it won’t be able to bear fruit until spring.
