Abscisic acid triggers whole-plant and fruit-specific mechanisms to increase fruit calcium uptake and prevent blossom end rot development in tomato fruit.
Calcium (Ca) uptake into fruit and leaves is dependent on xylemic water movement, and hence presumably driven by transpiration and growth. High leaf transpiration is thought to restrict Ca movement to low-transpiring tomato fruit, which may increase fruit susceptibility to the Ca-deficiency disorder, blossom end rot (BER). The objective of this study was to analyse the effect of reduced leaf tr...
متن کاملCalcium partitioning and allocation and blossom-end rot development in tomato plants in response to whole-plant and fruit-specific abscisic acid treatments
The mechanisms regulating Ca(2+) partitioning and allocation in plants and fruit remain poorly understood. The objectives of this study were to determine Ca(2+) partitioning and allocation in tomato plants and fruit in response to whole-plant and fruit-specific abscisic acid (ABA) treatments, as well as to analyse the effect of changes in Ca(2+) partitioning and allocation on fruit susceptibili...
متن کاملاثر مالچ پلی اتیلن سیاه و کلسیم نیترات بر رشد، عملکرد و پوسیدگی گلگاه (Blossom end rot)هندوانه رقم چارلستون‌گری
Watermelon (Citrullus Lanatus) cv. Charleston Gray is one of the most important cultivars grown in Iran. It has some good quantitative and qualitative characteristics but unfortunately is sensitive to Blossom End rot. To solve this problem, this experiment was conducted in a factorial manner in randomized complete block design with four replications in Research Station and Laboratories of Depar...
متن کاملتأثیر خشکی موضعی منطقه ریشه (PRD) بر روابط آبی، رشد، عملکرد و برخی ویژگی‌های کیفی گوجه‌فرنگی
Reduction in rainfall and shortage of water resources has caused major damages to agricultural sector. Therefore, it is necessary to employ new methods in order to optimize use of water resources. In this research, the effect of irrigation method of PRD on tomato growth was compared with the conventional irrigation method. The results showed an increase in water use efficiency and total soluble...
متن کاملComparative effect of partial root-zone drying and deficit irrigation on incidence of blossom-end rot in tomato under varied calcium rates
This study investigated the comparative effects of reduced irrigation regimes--partial root-zone drying (PRD) and conventional deficit irrigation (DI)--on the incidence of blossom-end rot (BER) in tomato (Solanum lycopersicum L.) under three Ca-fertilization rates: 0, 100, and 200mg Ca kg(-1) soil (denoted Ca0, Ca1, and Ca2, respectively). The plants were grown in split-root pots in a climate-c...
