If you reside somewhere north of the equator but south of the north pole, you may have noticed the shortening and darkening of our days lately. In fact, the days have been getting shorter ever since June. Shorter days with less sunlight coincide with cooling temperatures and increased precipitation, all of which hinder plant growth and maturity to a certain extent. Anyone who has tended plants for even a few days knows that temperature can be a fickle friend and sometimes foe; but plants also have a significant relationship with light and dark – one that is more complex, and often not as well-understood by growers. A Brief Terminology Le...

Either directly or indirectly, most plant problems are caused by environmental stress. Either directly or indirectly, most plant problems are caused by environmental stress. In some cases, poor environmental conditions (e.g., too little water) damage a plant directly. In other cases, environmental stress weakens a plant and makes it more susceptible to disease or insect attack. Environmental factors that affect plant growth include light, temperature, water, humidity and nutrition. It's important to understand how these factors affect plant growth and development. With a basic understanding of these factors, you may be able to manipulate plants to meet your needs, whether for increased leaf, flower or fruit production. By recognizing the roles of these factors, you'll also be better able to diagnose plant problems caused by environmental stress. Light Three principal characteristics of light affect plant growth: quantity, quality and duration. Quantity Light quantity refers to the intensity, or concentration, of sunlight. It varies with the seasons. The maximum amount of light is present in summer, and the minimum in winter. Up to a point, the more sunlight a plant receives, the greater its capacity for producing food via photosynthesis. You can manipulate light quantity to achieve different plant growth patterns. You can manipulate light quantity to achieve different plant growth patterns. Increase light by surrounding plants with reflective materials, a white background ...

Vernalisation in Plants Photoperiodism is the reaction of animals and plants to the length of a dark period or especially night. Plants show developmental response to photoperiodism, particularly with the delayed beginning of flowering. In plants, the effects of photoperiodism are classified in short-day plants, long-day plants and day-neutral plants. The short-day plants examples are cotton, marijuana, rice, sorghum, soya beans and green gram. The long-day plants examples are oat, pea, wheat, barley and lettuce. The day neutral plants examples are cucumber, tomato, rose and auto-flowering cannabis (Ruderalis). The process of flowering in these plants does not depend on photoperiodism. Therefore, unlike the short day and long day plants, they initiate the flowering process after reaching a certain developmental stage. In some cases, the process of flowering is in response to some other environmental stimuli such as vernalisation. [Image will be Uploaded Soon] Photoperiodism in Animals Just like plants, there are certain birds and animals that too show certain behaviour in response to the photoperiod effect. These behaviours include reproduction, migration, shedding of the skin, changing the fur colour, hibernation, aestivation, changing the size of reproductive organs etc. E.g., the canary bird changes the singing frequency depending on the photoperiod. Also, during the spring season, as there is more daylight, the male bird’s testicles grow in size, which allows more prod...

long-day plant A plant in which flowering is favoured by long days (i.e. days when there are more than 14 hours of daylight) and correspondingly short dark periods. There are two groups of such plants, species in which there is an absolute requirement for these conditions (such that flowering will not begin without them) and others in which flowering is merely hastened by them. Spinach, lettuce, and grasses are long-day plants; in Citation styles Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

When it comes to flowering plants, you’ll hear a number of different terms used to describe it including day neutral, short day plants, and long day plants. As living organisms, plants respond to their environment, such as deciduous trees changing colours and dropping their leaves in the fall. Day neutral plants refer to plants that flower regardless of the amount of light it is exposed to. Some examples of day neutral plants include cucumbers and corn. Short day plants refer to plants that flower when the amount of light it receives is shorter than a certain critical length, such as in the spring or fall. Some examples of short day plants are chrysanthemums. Long day plants refer to plants that flower when the amount of light it receives is longer than a certain critical length, such as in the summer. Some examples of long day plants are spinach and lettuce. These three definitions – day neutral, short day, and long day – are related to the photoperiodism, which is a physiological response to both periods of light and periods of darkness.

Common examples of short-day plants include chrysanthemums and poinsettia flowers, cotton, rice, and sugar cane. Are roses short-day plants? Short-day plants flower only when daylengths are less than 12 hours per day. The length of dark period is most crucial. You may also stimulate bloom in long day plants such as lilies, roses, petunias and spinach if daylengths surpass 12 hours. Table of Contents • • • • • • Things to consider Below are some things to consider when trying to figure out what are day neutral plants. What happens when long day plants are exposed to short days? Short-day plants flower when they are exposed to day length SHORTER than the critical maximum period. Long-day plants flower when they are exposed to day length LONGER than the critical minimum period. Short-day plants are also called as Long-night Plants. Long-day plants are also called as Short-night Plants. What is the difference between a short day plant and a long day plant? Short-day plants form flowers only when day length is less than about 12 hours. Many spring- and fall-flowering plants are short-day plants, including chrysanthemums, poinsettias and Christmas cactus. These are termed “long-day” plants. These bloom only when they receive more than 12 hours of light. Neutral Plants – Photoperiodism and vernalization What is DNP plant? Day neutral plants (DNP) do not depend upon the amount of darkness or daylight hours. Examples of day neutral plants are sunflower, cucumber, tomato. Examples o...

Photoperiodism is the effect of duration of light on living organism. It is also defined as the effect of photoperiod (duration of light) on living organism for inducing certain physiological activities like flowering and growth. It was first discovered by H.A. Allard & W.W Garner in 1920 A.D. It shows adverse effect on plant as compared to animal. In plants it either induce or reduce flowering as per the availability of duration of sunlight. Due to photoperiodism and its effect, plant only induce flower in certain season of the year. Photoperiodism in plants The pigment called phytochrome/ chromoprotein is responsible for photoperiodism which detects the duration of sunlight in plant. It acts as signal for detecting the suitable season for inducing flowering in plants. Based on the length of photoperiod, Allard and Garner classified plants into 3-types. • Short Day Plants • Long Day Plants. • Day Neutral Plants Short Day Plants The plants which require short duration of sunlight for flowering are called short day plants. It requires about 8-10 hrs. of sunlight. This type of plants are also called long night plant as they prefer short day and need not to exceed critical photoperiod. Short day plants flower in winter season due to short length of day and long duration of night which is favorable condition for flowering. Examples of Short Day Plants Tobacco, sugarcane, strawberry, Brassica campestris (mustard), soyabean, Salvia, Cannabis, Chenopodium etc. Long Day Plants The...

What is Photoperiodism? Photoperiodism is defined as the physiological and behavioral changes that an organism makes in response to the daily and seasonal changes of sunlight throughout the year. In plants, photoperiodism specifically refers to the physical and developmental response of the plant to the sunlight-to-darkness ratio. Each plant has what is called a critical photoperiod which is the minimal amount of light for that particular plant that is needed for it to grow, bloom, and thrive. Even though the photoperiodism and critical photoperiod of plants are measured by the amount of sunlight necessary, the plants actually track the night length through special light-sensitive proteins inside the plant. There are two main forms of the protein and the proteins change depending on what light the plant receives (light vs. dark). When under complete darkness, the nocturnal form is active while the diurnal is inactive. During sunlight, the nocturnal form becomes inactive while the diurnal form is active. How much darkness there is in the day determines the ratio of the two different forms of protein. In this way, the plant is able to "count" the total number of hours of darkness. When the ratio hits the critical photoperiod, the leaves release the plant growth regulators which then initiate the flowering process. One important detail is that the critical photoperiod is the amount of complete and continuous darkness. Even brief flashes of light during the darkness can interr...
