PLANT DEVELOPMENT DEPENDS ON TEMPERATURE. Plants require a specific amount of heat to develop from one point in their lifecycle to another, such as from seeding to the four-leaf stage. People often use a calendar to predict plant . development for management decisions. However, calendar days can be misleading, especially for early crop growth stages. For example, a cool May can greatly …
CO 2 concentrations have been steadily rising for more than two centuries. Increases in atmospheric CO 2 concentration affect how plants photosynthesise, resulting in increases in plant water use efficiency, enhanced photosynthetic capacity and increased growth. Increased CO 2 has been implicated in ‘vegetation thickening’ which affects
heat stress on plant growth and development has also enhanced. Higher night temperatures have given rise to Higher night temperatures have given rise to increase in respiration hence reducing the net gain in the form of grain yield.
Growth of crop The effects of mulches on plants are operative through the effects of mulches on soil water, soil temperature, structure and erosion.

of western Africa that plant growth ceases as soon as the P stored in the seed is exhausted (Mokwunye and Bationo, 2002). Soil P-deficiencies primarily result from either inherent low levels of soil P or depletion of P through cultivation.

Temperature is one of the determining factors, for plant growth, and is one of the major environmental constraints affecting photosynthetic efficiency and limiting the yield of crop plants (Bose et
Temperature has been found to affect the living organisms in various ways, for example it has significant role on the cells, morphology, Physiology, behaviour, growth, ontogenetic development and distribution of plants and animals.
Excessively low temperatures can also cause limiting effects on plant growth and development. For example, water absorption is inhibited when the soil temperature is low because water is more viscuous at low temperatures and less mobile, and the protoplasm is less permeable. At temperatures below the freezing point of water, there is change in the form of water from liquid to solid. The
tive effects of weather on our plants. Temperature Generally, plants grow faster with increasing air temperatures up to a point. Extreme heat will slow growth and also increase moisture loss. The temperatures for optimal growth vary with the type of plant. Some annual flowers and vegetables are extreme-ly sensitive to cold, and transplants should not be planted until temperatures are con
Light is an essential product in plant growth and development. As producers in most ecosystems, plants rely heavily on some sort of light source. T““`he presence of light plays a major role in plant morphology. Plants respond to the quality, quantity, and direction of light. Light is required in photosynthesis, a plant’s process of creating food and energy.1 The sun is the greatest light
In a detailed review on effects of tempera ture on plant growth, Went (18) reported that most of the tomato plant growth occurs at night.

The shape of this function also describes temperature effects on most biological functions, including plant growth and development. The function can be categorized by the three cardinal temperatures – minimum, optimum and maximum. Modellers frequently simplify the relationship into a stepwise linear function. The stepwise linear function has a plateau rather than an optimum temperature (Figure

Temperature has major effects on photosynthesis and respiration, plant growth and phenological development. Phenology is particularly important in cooler regions and at higher altitudes. As a rough guide, atmospheric temperatures experienced by crops decrease by about 1°C for each 2° increase in latitude, or for each 100 m increase in altitude. The bell-shaped responses to temperature shown
Climate change will alter plant development in ways that will have significant impacts on the function of crop plants and plants in natural ecosystems.

Name the limiting factors that effect plant growth. What Makes Plants Grow? The vital needs of a plant are very much like our own – light, water, air, nutrients, and a . proper temperature. The relative importance of each of these needs differs widely among plants. The ability of a plant species to spread throughout a geographic area is a direct result of its adaption to the abiotic and
Abstract. Wind affects plant growth, reproduction, distribution, death, and ultimately plant evolution. Some of the effects depend on the air boundary layers next to the aerial parts of a plant, across which gas and heat exchanges with the environment occur.
