“…The average yield of T2 treatment was the biggest among these treatments and the number was 41.14 kg/tree. The average yield of non-irrigated treatment (NI) was the smallest among these treatments with 25.88 kg/tree, but offered the biggest average single weights, 278.59 g, similar to the results of previous studies [20, 21]. Compared with non-irrigated treatment (NI), the increase rate of average yield of T1, T2, T3, T4 and T5 treatments were 55.3%, 59.0%, 52.2%, 47.7%, 18.7% respectively, the decrease rate of average single weights of T1, T2, T3, T4 and T5 treatments were 24.15%, 23.33%, 19.79% 12.87% and 19.06% respectively.…”

Although being one of the few drought-tolerant plants, mango trees are irrigated to ensure optimum and consistent productivity in China. In order to better understand the effects of soil water content on mango yield and fruit quality at fruit growth stage, irrigation experiments were investigated and the object was to determine the soil water content criteria at which growth and quality of mango would be optimal based on soil water measured by RHD-JS water-saving irrigation system through micro-sprinkling irrigation. Five soil water content treatments (relative to the percentage of field water capacity) for irrigation (T1:79%-82%, T2:75%-78%, T3:71%-74%, T4: 65%-70%, T5:63%-66%) were compared in 2013. Amount of applied irrigation water for different treatments varied from 2.93m3 to 1.08 m3. The results showed that mango fruit production and quality at fruit growth stage were significantly affected under different irrigation water amounts. Variation in soil water content not only had effects on fruit size, but also on fruit yield. The highest fruit yield and irrigation water use efficiency were obtained from the T4 treatment. Irrigation water amount also affected fruit quality parameters like fruit total soluble solids, soluble sugar, starch, titratable acid and vitamin C content. Comprehensive evaluation of the effect of indexs of correlation on irrigation treatment by subordinate function showed that when the soil moisture content were controlled at about 65–70% of the field water moisture capacity, water demand in the growth and development of mango could be ensured, and maximum production efficiency of irrigation and the best quality of fruit could be achieved. In conclusion, treatment T4 was the optimum irrigation schedule for growing mango, thus achieving efficient production of mango in consideration of the compromise among mango yield, fruit quality and water use efficiency.

“…Similar water potential gradients have been reported between fruits and leaves of pear trees (Yamamoto, 1983;Behboudian et al, 1994). Such internal water potential gradients can drive water redistribution from organs at higher water potential to organs at lower water potential and result in wilting of the source tissue.…”

Competition for water between inflorescences and leaves in cut flowering stems ofGrevillea‘Crimson Yul-lo’

SUMMARYGrevillea cv. 'Crimson Yul-lo' has large bright red terminal inflorescences on leafy stems and has recognised commercial potential as a cut flower crop. A major limitation is its relatively short vase-life, often terminated by early wilting of the inflorescence despite apparently turgid leaves. An investigation of the water relations of cut Grevillea 'Crimson Yul-lo' stems revealed that the water potential of inflorescences on intact stems in vases was significantly higher (i.e., less negative) than that of leaves from day-0 to day-3 of vase-life. Thereafter, the water potential of inflorescences declined more rapidly than that of leaves, accompanied by visible wilting of the tepals and styles of individual florets. Removal of leaves from the stems reduced both water uptake and water loss, and delayed the onset of a negative water balance in the inflorescence. Bagging of entire stems, leaves only, or inflorescences only, with microperforated plastic film to reduce transpiration, reducing leaf number to reduce leaf area, or supplying abscisic acid to reduce leaf stomatal aperture, all aided relative fresh weight retention by stems and extended vase-life. Four or six leaves on a stem caused greater loss in inflorescence water content than zero or two leaves. Considered collectively, these findings show competition for water between the inflorescence and the leaves in cut Grevillea 'Crimson Yul-lo' stems contributes to the onset of inflorescence wilting and their short vaselife.3 revillea is a large genus within the family Proteaceae and it contains over 300 species (Joyce and Beal, 1999), many of which are grown world-wide (Costin and Costin, 1988;Joyce and Beal, 1999;Joyce, 2004). Many grevilleas, especially hybrids of subtropical and tropical species, are woody shrubs or small trees with attractive large, colourful inflorescences and soft, divided fern-like foliage that make them appealing as landscape plants. Their inflorescences also have commercial potential as cut flowers (Costin and Costin, 1988;Joyce, 2004), but a major limitation to their use as cut flowers is their relatively short vase-life of often less than 1 week (Faragher, 1989;Joyce et al., 1996;Joyce and Beal, 1999;Joyce, 2004). Cut stems of Grevillea 'Crimson Yul-lo' (Grevillea banksii × Grevillea 'Misty Pink') have large bright-red terminal inflorescences consisting of 90−120 florets at various developmental stages arranged along a single floral rachis ( Figure 1A, B), but the inflorescences have a vase-life of only three-four days in water.A number of factors influencing the longevity of cut Grevillea flowers have been studied.The vase-life of Grevillea 'Majestic' inflorescences harvested in Winter was generally longer than that of Summer-harvested inflorescences (Vuthapanich et al., 1993). The vase lives of Grevillea 'Sylvia' and Grevillea 'Honey Gem' were dependent upon the harvest maturity stage, with optimum maturity being characterized by opening of the lowest florets (Joyce and Beal, 1999).

“…Monthly rainfall deficits during the vegetation season of the pear tree (April-October) in the Isparta and Bydgoszcz regions is shown in Figure 2. The water deficit negatively affects the physiological parameters and the yield of pear fruit [8][9][10][11][12]. According to Behboudian et al [8] water deficit in pear cultivation is unfavorable, especially at the beginning of the growing season, because it negatively affects water relations, photosynthesis and fruit growth.…”

“…The water deficit negatively affects the physiological parameters and yield of pear fruit. Trees subjected to prolonged water deficit usually produce smaller fruit and lower fruit yields [8][9][10][11][12]. In the literature there is information about cultivation or water requirements of fruits trees in the area of Isparta (Turkey) and Bydgoszcz (Poland) regions [7; 13].…”

Abstract. The purpose of the study has been an attempt at a comparison of pear-tree water needs in the vegetation period in the Bydgoszcz region (Poland) and in the Isparta region (Turkey). The paper refers to the 1984-2014 temperature and rainfall values in the Bydgoszcz and Isparta regions. To determine the reference evapotranspiration (ETo), the calculation model by Hargreaves -modified by Droogers and Allen -was applied. Potential evapotranspiration (ETp), identified with pear-tree water needs, was determined with the method of crop coefficients proposed by Doorenbos and Pruitt. In each of the seven months considered (April-October) higher pear-tree water needs occurred in the Isparta region. The highest monthly pear-tree water needs were noted in July and in the studied period, respectively for the Bydgoszcz and Isparta regions, they were on average 105 mm and 215 mm. Pear-tree water needs throughout the vegetation period (April-October) were much higher (by 114 %) in the Isparta region than in the Bydgoszcz region. The highest rainfall deficits occurred in July and, respectively for the Bydgoszcz and Isparta regions, amounted to 33 mm and 195 mm.
