“…Chilling is usually effective at temperatures below 7°C (Luedeling, 2012). Under natural conditions, the end of the dormancy period and the ability to resume growth in temperate fruit trees are mediated by chill accumulation (Alburquerque, García-Montiel, Carrillo, & Burgos, 2008;Gariglio, Weber, Castro, & Micheloud, 2012;Oukabli & Mahhou, 2007;Rahemi & Pakkish, 2009;Segantini, Leonel, Cunha, Ferraz, & Ripardo, 2014). The main challenge for temperate fruit production in the tropics is to overcome the dormancy period (Erez, 2001).…”

The present study aimed to review the advances in the production of temperate fruits to determine future research directions that improve production in the tropics. Temperate fruits are no longer only produced in regions characterized by a cold winter period. These fruits are also produced in the sub-tropical and tropical regions characterized by mild winter or even the absence of chilling conditions often required by the tree to break dormancy. Currently, temperate fruit production is possible in certain regions of South America, Africa and Asia that are near to the Equator. However, temperate tree fruit production in tropical regions requires modified techniques to overcome dormancy and allow adequate flowering, growth and productivity. The main approaches taken are the development of cultivars with low chilling requirement, chemical induction of budbreak, interruption of irrigation during the winter period, defoliation, orchard densification, and double pruning. Breeding has become a key tool in the advancement of temperate fruit growing in the tropics, especially with the development of low chilling requirement cultivars.

“…Furthermore, phenological data can also be used to help predict interannual changes in tree phenology (PETRI et al, 2008). Thus, knowledge of the timing of phenological events and their variability can help producers obtain more stable crop yields and quality, thereby reducing environmental risks (GARIGLIO et al, 2012;SIMÕES et al, 2015).…”

FACTORS AFFECTING PHENOLOGY OF DIFFERENT Citrus VARIETIES UNDER THE TEMPERATE CLIMATE CONDITIONS OF SANTA FE, ARGENTINA

et al. 2018

The aim of this study was to characterize the phenology of different sweet orange, tangerines and tangerine hybrid varieties growing under the temperate climate conditions of Santa Fe Province, Argentina. Phenological stages were observed weekly during five consecutive years using a BBCH (Biologische Bundesanstalt, Bundessortenamt and Chemical industry) scale adapted for Citrus trees. All varieties showed a winter rest period from June to August. ‘New Hall’ and ‘Navelina’ varieties were the first to reach sprouting stage, whereas ‘Okitsu’ was the last. Inception of flowering occurred from August 13th to September 6th; and full bloom from September 12th to October 2nd. Fruit harvest started with the ‘Okitsu’ cultivar in March, and continued over a 7-month period. Interannual variation for inception of sprouting was high (44 days), and sprouting was correlated with both thermal accumulation (above 13ºC) and the amount of solar radiation measured during July (p<0.0001; r2=0.79). Navel oranges and the ‘Murcott’ hybrid bloomed 5–15 days earlier than other varieties, increasing probability of damage by late frosts.

“…Carbohydrate accumulation prior to dormancy is critical for deciduous trees, as they rely on carbohydrate reserves for budbreak and growth resumption in spring [ 16 ], and an increase of whole tree carbon assimilation ( A tree ) during fall as a consequence of delayed senescence (DS) could contribute to these reserves. However, DS results in the reduction of chill hour accumulation leading to erratic phenology patterns, such as bloom timing in spring [ 26 , 27 ]. We hypothesized that young peach trees that experienced DS and/or were well-watered (100% ET) during fall would have higher A than trees that experienced normal senescence (NS) and/or the trees that received 50% the well-watered amount (50% ET).…”

Variable fall temperature and moisture conditions may alter leaf senescence of deciduous fruit trees, influencing carbon assimilation before dormancy and phenology the following spring. This study explored gas exchange of young peach trees (Prunus persica (L.) Batsch) when senescence proceeded normally or was delayed during the fall under two soil moisture treatments: Well-irrigated trees or water deficit. Results showed leaf carbon assimilation was similar between the senescence treatments, but whole tree assimilation was estimated to be greater in delayed senescence trees compared to normal senescence trees based on timing of defoliation and total leaf area. The effect of soil moisture on carbon assimilation was not consistent between years. Delayed sap flow and bloom time resulted as a consequence of delayed senescence the previous fall, but soil moisture did not affect spring phenology.
