In citrus the fruit maturity and quality is influenced by temperature. The temperature variations and severity of winter and frost and hot summers affect the plant growth and productivity. Temperature may fall as low as 0°C or even less in winter and may go as high as 48°C in North Indian plains. Abstract. Temperature is one of the most important factors affecting fruit coloration. Because of recent effects of global warming, inferior coloration has become a serious problem in many fruits, especially those for which coloration is important for the commercial appearance and value, such as grapes, apples, citrus fruits, and by: 6.
reasonably good cultural and crop protection practices, climate is the most important of the clfmate-soil-cul~ure coaplex causing differences in growth, yield, and fruit qualities among commercial citrus producing areas. Studies were conducted to determine the effect of different storage temperatures (5, 15, 20 and 25°C) on the flavour of Late Frost orange cv. Valencia stored for up to one month (following a pre-experimental 2 month storage period at 5°C). Samples were instrumentally analysed every week for titratable acidity, soluble solid content, maturity index and ethanol and acetaldehyde by:
Adverse effects of high temperature on cereal crops vary with the timing, duration, and sternness of the heat stress (Fahad et al., b). High temperature stress reduced number of spikes and number of florets per plant in rice and seed-set in sorghum was also negatively affected under similar conditions (Prasad et al., ; Fahad et al Cited by: The results of our study suggested that the small effects on soil water and temperature changes created by surface mulch had limited impact on citrus fruit yield in a normal year (e.g., in ). However, SM practices can positively impact citrus fruit yield in extreme weather by:

This report is mainly confined to temperature effects on citrus crop and includes a list of a wide range of references. Effect of High Temperature on Crop Productivity and Metabolism of Macro Molecules presents a comprehensive overview on the direct effect of temperatures defined as high, a definition which increasingly includes a great number of geographic regions.
As temperature impacts the number of base growth days, it is necessary to adapt plant selection, strategize planting times,Author: Amitav Bhattacharya.

Each crop species has its own range of temperature maxima and minima at different developmental stages beyond which all these processes are inhibited. The reproductive stage is on the whole more sensitive to heat stress, resulting in impaired fertilization, causing abortion of flowers.

of the impacts of temperature change on crop production at regional level. The impacts of mean T on crop production were represented in some crop models by growing degree days (GDD).
However, the effect of extreme Ts on crop production is lacking in many models which may bias the projection of the impacts of climate 0 10 20 30 40 Citrus fruit production and quality are influenced by many factors, including climatic conditions and produc-tion practices.
In subtropical climates, the temperature usually falls below 70°F for several months dur-ing winter. This period of cool temperatures causes growth to cease and citrus trees to become dormant for about three months.
However, the effect of an increase in temperature was greater in humid areas (e.g., Sao Paulo) where an increase in average temperature by 1 °C will result on average in an 8% increase of IRR.
The effect of temperature was smaller in Riverside and Riverland where an average increase of IRR by 3% is projected due to an increase in average temperature by 1 ° by: 6.
An extensive discussion of additional aspects of fruit development and maturation may be found in Spiegel-Roy and Goldschmidt (). Temperature is the most important environmental factor affecting the citrus crop (Gat et al., in press) and, as such, must File Size: KB.

For most grain crops, there is much greater genotypic variation in thermal requirements for vegetative than for reproductive development. increase as biomass levels increased.

Climatic variables temperature as well as rainfall has very harmful effect on the production of citrus fruit. These result shows that there can be severe repercussion in Pakistan's horticulture. This sector of the economy shows a very negative effect put by climatic variables that are due to the variation in rainfall as well as temperature.
