| Calcium (Ca2+) is a nutrient in tomato plants, of which deficiency usually causes several problems including a physiological disorder known as blossom-end rot (BER) in the fruit. The objective of this study was to evaluate and identify morphological and physiological characteristics related to the susceptibility of tomato varieties to BER. The varieties studied were ‘Amalia’, ‘IPA-6’, ‘M-82’, ‘Mara’, and ‘Nagcarlan’, presenting different fruit formats. Physiological parameters that negatively correlated with BER were plant water potential, leaf area, plant dry mass, relationship between proximal/distal Ca2+, K+ content in the proximal and distal portions of the fruit, and proximal Ca2+ content. Physiological parameters that positively correlated with BER... |

| Pepper crops (Capsicum annuum L.) represent a very important production sector in the Southeast of Spain. Specifically, in the province of Almería, approximately 7000 hectares are grown every year. Due to the economic importance that this crop has for the region and the withdrawal of soil fumigants from the market, agronomic techniques have been adopted with the aim of controlling some soil pathogens and increasing the yield and quality parameters of the fruits obtained. The use of grafted pepper plants is not, as yet, very well established in this region, due mainly to the lack of commercial rootstocks that satisfy the producers of this vegetable. In this experiment three pepper rootstocks were assessed. An experiment was designed with four treatments and... |
