“…Previous works have also shown that fruit growth might be promoted by increased daily solar radiation (Kitano et al, 1998;Sonneveld and Voogt, 1991), increased temperature, or a combination of warm weather and high solar radiation Wui and Takano, 1995) due to increased photosynthetic rates and consequent photoassimilate translocation into fruit Ho and White, 2005;Walker and Ho, 1977). Since the variation in watersoluble Ca in the distal part of the young fruit was highly related to the rate of fruit growth in the susceptible cultivar 'Momotaro Fight' (Table 7), it is highly possible that the promotive effects of temperature and solar radiation favoring rate of fruit growth (Table 4) are more significant on cultivars with high fruit growth rate and large potential fruit size, aggravating the susceptibility of these cultivars to BER, compared to smallsized cultivars.…”

“…BER is often observed during the phase of rapid fruit growth 2-3 weeks after anthesis (Adams and ElGizawy, 1988;Ho and White, 2005;Saure, 2001;Sonneveld and Voogt, 1991;Wui and Takano, 1995). In this study, we examined two cultivars with different sizes and susceptibility to BER under hydroponic condition.…”

“…Rapid fruit expansion is believed to be a dominant factor to dilute fruit Ca concentration and increase fruit susceptibility to BER during the fruit enlarging period Dekock et al, 1982;Ikeda et al, 2017;Ooyama et al, 2016;Wui and Takano, 1995). Fruit growth is favored under certain conditions of high temperature and solar radiation, perhaps due to accelerated metabolism and increased photoassimilate supply to the fruit (Ho and White, 2005;Ho et al, 1993).…”

Comparative Analysis on Blossom-end Rot Incidence in Two Tomato Cultivars in Relation to Calcium Nutrition and Fruit Growth

et al. 2018

Blossom-end rot (BER) in tomato has been generally reported as a calcium (Ca)-related physiological disorder influenced by cultivar and environmental factors. In our previous works, we found that different fruit-sized cultivars could share a similar threshold value of water-soluble Ca. In addition, seasonal susceptibility to BER was closely related to fruit growth rate. This study aimed to clarify the effect of fruit growth rate as a dominant factor determining the susceptibility in different fruit-sized tomato cultivars.

“…As Saure (2001) summarized in his review, various cultural practices and environmental factors, such as fruit thinning (de Kock et al, 1982), increased daily radiation (Sonneveld and Voogt, 1991), increased temperature or a combination of warm weather and high irradiance Wui and Takano, 1995), have been reported to increase the incidence of BER by promoting the rate of fruit growth. Accelerated fruit growth increases Ca demand in the fruit for cell expansion and Ca transport to the fruit.…”

To understand the factors affecting the incidence of blossom-end rot (BER), the effect of the Ca/K ratio (4/12-12/4, in me·L -1 ) in nutrient solutions and Ca concentration in fractions in the distal part of young tomato fruits immediately before BER symptoms appear were investigated for three seasons. The rate of BER incidence increased with a decrease in the Ca/K ratio in the supplied solutions in the summer and spring, but little difference was observed in the winter. Ca concentration was highest in winter and lowest in summer, and the concentration in fractions decreased with a decrease in the Ca/K ratio of the solutions. When the results of all three experiments were pooled, among the fractions, water-soluble Ca concentration was found to have the highest significance in the relationship to BER incidence. The risk of BER incidence in rapidly growing tomato increased to a critical level when water-soluble Ca in the distal part of the fresh fruit decreased to less than 0.20 μmol·g -1 FW. Multiple-regression analysis revealed that the concentration of water-soluble Ca, which is predominantly recovering apoplastic or cytoplasmic Ca 2+ , and total Ca, which has been translocated during fruit development, are significantly affected by solar radiation and Ca concentration in the supplied solution rather than air temperature.

Noviembre 2015 Programa de Doctorado en Recursos y Tecnologías Agrarias I | SUMMARYPepper is a vegetable of extraordinary economic and social importance in our country. Unfortunately, the persistent exploitation of the land, the monoculture and the intensification of production processes, lead to the development of soil diseases. This coupled with the abiotic stress, mainly the salinity of waters and soil, suboptimal temperatures and water stress, can induce the appearance of physiological disorders in peppers as the Blossom-end rot (BER) and cracking or cracked, induce plant senescence and decrease not only production, but also the quality of the product. Salinity and water shortages are two among the biggest environmental problems that crops have to face in the Mediterranean area. A way to overcome the stresses under the prism of an ecological or integrated crop management, is the use of grafted plants as adaptation strategy. Although there has been remarkable progress in this technique (mainly in tomato, melon, watermelon), in the cultivation of pepper use remains rare. In this Doctoral thesis several pepper genotypes have been selected through different physiological parameters which indicate tolerance to salt and water stress. Commercial cultivars were grafted onto the selected genotypes and were grown under water stress, salinity and control conditions studying several physiological, agronomic responses and the interaction rootstock/scion.The results obtained concluded that genotypes selected and used as rootstocks improved commercial varieties to salt and water stress tolerance, both in terms of performance (commercial production) compared to other commercial characters and variety without grafting. Different physiological mechanisms explain the tolerance to stress, such as the ability to maintain the water potential through an osmotic adjustment, stimulation of the antioxidant system, exclusion II | or retention of toxic ions (Na + and Cl -) in saline in the roots and the maintenance of photosynthesis which allows to maintain the metabolic functions of grafted plants and production. III | RESUMENEl pimiento es una hortaliza de extraordinaria importancia económica y social en nuestro país. Lamentablemente, la persistente explotación del suelo, el monocultivo y la intensificación de los procesos de producción, conducen al desarrollo de enfermedades del suelo. Esto unido a los estreses abióticos, principalmente la salinidad de las aguas y del suelo, temperaturas subóptimas y estrés hídrico, puede inducir la aparición de fisiopatias en el pimiento como el Blossom-end rot (BER) y cracking o rajado, inducir senescencia vegetal y disminuir no solo la producción, sino también la calidad del producto.La salinidad y la escasez de agua son unos los mayores problemas medio ambientales a los que tienen que hacer frente los cultivos en el área Mediterránea. Un modo de sortear los estreses bajo el prisma de un manejo integrado o ecológico del cultivo, es la utilización de plantas injertadas como estrategia de adaptació...
