“…In general, the total conductance of the fruit epidermis is much less than that of leaves (Knoche et al, 2001). Therefore, the water loss from the fruit surface should be lower than that from leaves under the same vapor pressure deficit.…”

Water flows in the stem and peduncle of mango fruit were monitored, and the surface transpiration from the fruit was measured during the fruit-growing season. The stem heat balance method was used on the peduncle to monitor the inward water flow during the nighttime, and the reverse water flow from the fruit during the daytime when the stem transpiration water flow increased. This diurnal fluctuation pattern in the water flow was more evident in mature fruit than in young fruit. In mature fruit, the daily water loss due to the reverse flow was estimated to be 3% of the fruit weight. The reverse flow water loss and transpired water loss were compensated for by nocturnal inward water flow, through the peduncle, of 30 g over 15 h. These results were well supported by measurements of fruit dimensions, which indicated a circadian rhythm of contraction and expansion. The reverse flow amounted to 80% of the water loss from the daytime contraction of the fruit, a much greater proportion than the fruit surface transpiration.

V6T 1Z1 (R.J.) Cuticular waxes coat all primary aboveground plant organs as a crucial adaptation to life on land. Accordingly, the properties of waxes have been studied in much detail, albeit with a strong focus on leaf and fruit waxes. Flowers have life histories and functions largely different from those of other organs, and it remains to be seen whether flower waxes have compositions and physiological properties differing from those on other organs. This work provides a detailed characterization of the petal waxes, using Cosmos bipinnatus as a model, and compares them with leaf and stem waxes. The abaxial petal surface is relatively flat, whereas the adaxial side consists of conical epidermis cells, rendering it approximately 3.8 times larger than the projected petal area. The petal wax was found to contain unusually high concentrations of C 22 and C 24 fatty acids and primary alcohols, much shorter than those in leaf and stem waxes. Detailed analyses revealed distinct differences between waxes on the adaxial and abaxial petal sides and between epicuticular and intracuticular waxes. Transpiration resistances equaled 3 3 10 4 and 1.5 3 10 4 s m 21 for the adaxial and abaxial surfaces, respectively. Petal surfaces of C. bipinnatus thus impose relatively weak water transport barriers compared with typical leaf cuticles. Approximately two-thirds of the abaxial surface water barrier was found to reside in the epicuticular wax layer of the petal and only one-third in the intracuticular wax. Altogether, the flower waxes of this species had properties greatly differing from those on vegetative organs.

“…This humidity-sensitive polar path of cuticular water permeability is arranged in parallel with the humidityindependent non-polar path formed by lipophilic wax components of the cuticle. Cuticular conductance can be affected by cuticle thickness (Knoche et al, 2001), which varies according to fruit growing conditions. It has been shown that cuticle thickness of some plants was reduced when growth occurred in high-humidity environments (Tribe et al, 1968).…”

Mango, a tropical fruit of great economic importance, is generally harvested green and then commercialised after a period of storage. Unfortunately, the final quality of mango batches is highly heterogeneous, in fruit size as well as in gustatory quality and postharvest behaviour. A large amount of knowledge has been gathered on the effects of the maturity stage at harvest and postharvest conditions on the final quality of mango. Considerably less attention has been paid to the influence of environmental factors on mango growth, quality traits, and postharvest behaviour. In this paper, we provide a review of studies on mango showing how environmental factors influence the accumulation of water, structural and non-structural dry matter in the fruit during its development. These changes are discussed with respect to the evolution of quality attributes on the tree and after harvest. The preharvest factors presented here are light, temperature, carbon and water availabilities, which can be controlled by various cultural practices such as tree pruning, fruit thinning and irrigation management. We also discuss recent advances in modelling mango function on the tree according to environmental conditions that, combined with experimental studies, can improve our understanding of how these preharvest conditions affect mango growth and quality. Key words: environmental conditions, fruit load, irrigation, shelf life, size, taste Uma revisão dos fatores pré-colheita que influenciam o crescimento, qualidade e comportamento pós-colheita de frutos de manga: Manga, um fruto tropical de grande importância, é geralmente colhido verde e comercializado após um período de armazenamento. Infelizmente, a qualidade final da manga na prateleira é altamente heterogênea, em termos de tamanho do fruto, qualidade do paladar e comportamento pós-colheita. Tem-se obtido uma quantidade expressiva de informações sobre os efeitos do estádio de maturação e condições pós-colheita sobre a qualidade final da manga. Contudo, tem-se dado atenção consideravelmente menor à influência dos fatores ambientes sobre o crescimento da manga, características de qualidade e comportamento pós-colheita. Neste artigo, faz-se uma revisão dos estudos sobre manga, evidenciando-se como fatores ambientes afetam o acúmulo de água e de matéria seca estrutural e não-estrutural nos frutos durante o seu desenvolvimento. Discutem-se essas alterações com relação à evolução de atributos de qualidade dos frutos ainda nas plantas e após a colheita. Os fatores de pré-colheita abordados são luz, temperatura, disponibilidades de água e de carbono, raleio de frutos e manejo da irrigação. Discutem-se também recentes avanços sobre modelagem associada à função do fruto na planta, conforme as condições ambientes que, combinados com estudos experimentais, pode melhorar a nossa compreensão sobre como as condições de pré-colheita afetam o crescimento e a qualidade da manga.
