The key Areas Related to Crop Physiology
Did you ever study the biology of humans? Have you ever tried to figure out how your muscles function during a workout? Ever wondered how kids grow up? Human physiologists investigate how the human body functions. Crop physiologists study the growth and operation of plants similarly. Let’s learn about the key areas of crop physiology:
Plant Breeding
Crop alteration is a widely used practice in agriculture. Altering crops with the help of breeding practice brings changes in the genetic structure of a plant. It helps the farmers in the development of the crops which possess more beneficial attributes. As an effect, these crops become more suitable for society. The larger fruits or seeds are an example in this case as those products are more economical. Production of drought-tolerance crops is another useful application. Such crops can be produced in harsh environmental conditions. The recent developments in crop physiology and plant breeding enable farmers to produce pest-resistant crops. Such products have a lower risk of getting damaged. As an effect, the losses in agriculture were reduced.
Significant Advancements in Plant Breeding
The plant breeding domain has experienced several new advancements. These advancements are based on the studies done by Gregor Mendel, in the area of plant physiology. His works developed knowledge of recessive and dominant alleles. The findings were ignored for several years. Later, the same findings provided plant breeders with a better understanding of breeding techniques and genetics. The widely used crop breeding development includes the use of techniques which enable the farmers to choose a plant with persevered traits. The other developments in the domain include cross-pollination and self-pollination along with the use of molecular techniques for modifying the organism genetically.
Domestication of Plants
Domestication is another important practice in the domain of agriculture. It helps to enhance disease resistance. It also increases the tolerance to the drought. Additionally, domestication leads to making harvesting easier. The taste of the crops improves which is another benefit of domestication. Finally, domestication increases the nutritional value of the food. It is another benefit of the domestication.
The knowledge of crop physiology also helps the farmers to understand the effects of variation in farming techniques such as pest control using chemicals, use of fertilizers and controlling growth using chemicals. The variation in the crop is also observed due to the changes in climate and genetics.
Many students find this topic hard to grasp or understand. Hence, they can get online assignment help service to understand this topic in a much easier way.
Genetic Engineering of Plants
Studying the physiological features of plants is necessary to determine the effects of genetic engineering. Genetically modified organisms (GMOs) are organisms which possess modified genes. Genetic engineering techniques are used for altering the genetic materials It is also known as the recombinant DNA technology. These techniques are often used to develop new crops. The other benefits of genetically modified crops are higher nutritional value, increased level of durability, and a higher level of resistance to the virus and insects.
Development of Herbicide-resistant Seed
The development of Herbicide-resistant Seed is another instance of genetic engineering and its applications in the domain of physiological studies of plants. When the gene is modified in the seeds, the plants become able to tolerate a higher level of exposure to herbicides. Controlling weeds is one of the crucial activities in farming. By using the modified seeds, the farmers become able to produce a crop which can tolerate the herbicides. Therefore, controlling the weeds in the fields becomes easier.
Development of Insect-Resistant Crops
Genetic engineering techniques are used to develop insect-resistant crops. These crops are modified using the gene found in the soil bacterium Bacillus thuringiensis (Bt). These crops generate a toxin for the insects. In this way, the attacks of the insects are prevented.
Coping with Global Warming
Global warming is one of the key issues in the current agricultural systems. Both global warming and agricultural practices are interrelated to each other. Global warming impacts agriculture by bringing changes in average temperatures. The pattern of rainfall also changes with global warming. With the changing nature of the global climate, weather extremes are being observed more frequently. For example, incidents like heat waves and storms are being observed in a frequent manner. The change in weather also brings changes in the natural pests and diseases. The level of ground-level ozone concentrations along with the atmospheric carbon dioxide is changing with the climate. It indicates that the plants are being exposed to harsher weather in the modern days.

The exposure to extreme weather is impacting the crops in different ways. The nutritional quality of the crops is being changed due to the adverse impacts of weather. Global warming is leading to the rise of sea levels. As an effect, crop production in the low-altitude countries is being affected. Global warming might cause food insecurity in some areas. Under these circumstances, understanding plant physiology is especially necessary to develop strategies for protecting the crops.
Role in Horticulture
Horticulture is another area which is closely related to plant physiology. It is defined as the study which includes the culture of plants. Horticulture primarily focuses on producing food and materials for beauty and comfort. The key areas of focus in the domain of horticulture are– the restoration of the landscape, conservation of plants, management of soil, designing the garden and the landscape, and development and maintenance of the garden.
Key areas of Horticulture
The primary activities in Horticulture can be classified in the following manner—
Pomology
It deals with fruit culture. The activities in Pomology mainly include the production of pome fruits such as pear, apple and quince. It also includes the production of stone fruits such as cherry, peach, nectarine, plum and apricot. Production on small fruits such as raspberry, blueberry, grape and strawberry falls under the domain of Pomology. Finally, the production of nut tree fruits is also one of the notable activities in the field of Pomology.
Vegetable Production
It is the activity which deals with the culture of food crops. The crops are obtained from vegetable plants. Different parts of the vegetable plants are used as the product. Such parts include fruits, roots, and seeds.
Floriculture
It is a domain that deals with the growing of flowers. The domain also focuses on growing the bedding plants, potted plants, bulbs and floral design.
Environmental Horticulture
It is the domain which deals with nursery production of woody plants and herbaceous. The domain also emphasizes managing and designing the landscape.
Postharvest Physiology
This branch of horticulture is concerned with gathering, managing, and storing crops. Fruits, flowers, and vegetables are among the crops under domain management. If, on the other hand, you are unable to do assignments based on postharvest physiology for whatever reason and would prefer to pay someone to do your assignment, then there are many reliable services available online that can help you.
The key difference between agriculture and horticulture is the scale of production. Agriculture aims at the production of the crop on a large scale. On the contrary, horticulture emphasizes producing a crop on a smaller scale. However, in both domains, knowing the physiology of plants is equally important. In horticulture, the application of skills, knowledge and technology is needed to produce plants which meet the food-related and non-food requirements. The knowledge of the physiological attributes of the plants is required for cultivation and propagation purposes.
The application of knowledge aims at the improvement of the growth rate of the plants, increasing the yields, improving the quality and enhancing the nutritional value. In horticulture, the presence of the insects can damage the plants. Similarly, plants can also be damaged due to diseases. The knowledge of physiology plays a crucial role in preventing such attacks.
