“…Optimum temperature range in citrus (Citrus sinensis L. Osbeck) is 22 À 27°C and temperatures greater than 30°C increased fruit drop (Cole and McCloud, 1985). During fruit development when the temperatures exceed the optimum range of 13 À 27°C with temperatures over 33°C there is a reduction in Brix (sugar content), acid content, and fruit size in citrus (Hutton and Landsberg, 2000). Temperature stresses on annual and perennial crops have an impact on all phases of plant growth and development.…”

a b s t r a c tTemperature is a primary factor affecting the rate of plant development. Warmer temperatures expected with climate change and the potential for more extreme temperature events will impact plant productivity. Pollination is one of the most sensitive phenological stages to temperature extremes across all species and during this developmental stage temperature extremes would greatly affect production. Few adaptation strategies are available to cope with temperature extremes at this developmental stage other than to select for plants which shed pollen during the cooler periods of the day or are indeterminate so flowering occurs over a longer period of the growing season. In controlled environment studies, warm temperatures increased the rate of phenological development; however, there was no effect on leaf area or vegetative biomass compared to normal temperatures. The major impact of warmer temperatures was during the reproductive stage of development and in all cases grain yield in maize was significantly reduced by as much as 80 À 90% from a normal temperature regime. Temperature effects are increased by water deficits and excess soil water demonstrating that understanding the interaction of temperature and water will be needed to develop more effective adaptation strategies to offset the impacts of greater temperature extreme events associated with a changing climate. & 2015 Published by Elsevier B.V.

“…Environment-generated variability was observed among the sites in terms of orange fruit mass, firmness, fruit rind color, acidity and TSS. These differences are explained by the influence of environmental factors on fruit quality attributes, as previously documented for fruit size [34], rind color break and color intensity [6], percentage of fruit juice [16], juice acidity, sugar content and TA/TSS ratio [35][36][37]. However, in Corsica, differences in fruit maturation did not appear to be associated with the constant FDF.…”

Abscission of Orange Fruit (Citrus sinensis (L.) Osb.) in the Mediterranean Basin Depends More on Environmental Conditions Than on Fruit Ripeness

Orange fruit abscission usually occurs at the final stage of fruit maturation but in some areas of citrus production, in advance of the usual harvest period, and sometimes suddenly and intensely. The reasons for this precocious citrus fruit abscission remains unclear. Therefore, the aim of this study was to try to clarify what the determinants of this phenomenon are. A multi-site experimentation was carried out on six orange cultivars, in Corsica, Spain and Tunisia where the phenomenon of early massive fruit drop varies. Climatic parameters, fruit maturity parameters and fruit detachment force (FDF) were recorded along the fruit maturation period. Respectively to the fruit drop, the FDF decreased in Tunisia and in Spain until the fruit falls, whereas in Corsica, it remained relatively constant throughout fruit maturation. Although data on fruit maturity parameters (rind color, acidity and total soluble solids) differed at the three sites, their evolution was similar during the period of maturation. FDF was not related to changes in any fruit maturity parameters, and more likely depended on changes in temperatures on days when the mean temperature was above 13 °C. Massive fruit abscission could be linked to the earlier more rapid restart of vegetative growth in Tunisia and Spain than in Corsica.

“…The number of flower in fruit was more at 30C temperature (Carew et al, 2003). The reduction in fruit size, sugar and acid content when air temperature was 35C reported by (Hutton and Landsberg, 2000). Sunburn in fruits can be attributed to heat/light stress.…”

Heat stress is one of the most ominous abiotic factors which limit the productivity and quality thereby resulting in to huge economic losses. High temperature affects the morphological, anatomical and physiological and biochemical changes in plant system. The success in overcoming heat stress is limited owing to poor knowledge of heat stress during critical stages of fruit crops. There is urgent need to improve heat stress tolerance by using traditional breeding and transgenic approach. In this paper, we have discuss the effect of heat stress and possible management techniques viz., selection of fruit crops, cultivars, rootstocks, canopy management, irrigation, nutrient management, mulching, growth regulator and use of bagging and film spray etc. which can be used to alleviate heat stress in fruit crops.
