It is well-known that an irreversible decrease in serum viscosity occurs when tomato juice is concentrated by evaporation into paste. Several studies have suggested that the loss in serum viscosity is due to pectin depolymerization, caused by the high temperatures used during industrial tomato paste production. This study demonstrates that conformational changes in pectin may play a more import...

The effect of five antioxidants (citric acid, salicylic acid, benzoic acid, ascorbic acid, and sodium citrate) on the resistance of tomato plants (Lycopersicon esculentum Mill) to early blight disease incited by Alternaria solani was investigated in vitro and in vivo. The results indicated that all of the antioxidants tested markedly inhibited the mycelial growth of A. solani in vitro. The degr...

Research project entitled “Yield and economic dynamics of intercropping in summer vegetables ” was conducted at Horticultural Research Farm, NWFP Agricultural University, Peshawar (Pakistan) during 1999 and 2000. Summer vegetables were evaluated alone and in various combinations for their yield, land equivalent ratio and income in intercrop combinations. Each plot was 4x4 m whereas number of ro...

The study was carried out in the Research field of Regional Agricultural Station (RARS), Hathazari, Chattogram, Bangladesh from November 2019 to April 2020 observe effect transplanting date and variety for tomato production. Eight open-pollinated varieties viz. BARI tomato-2, tomato-3, tomato-14, tomato-15, Marglobe, Roma VF, Riograndi, Khattabegun were considered as factor A two dates 18th Dec...

orobanche aegyptiaca, commonly known as egyptian broomrape, is a holo-parasite that causes high economic damages on tomato production in iran. breeding for resistance is the most economic and feasible method to reduce broomrape infestation. 20 tomato cultivars and four wild tomato species were screened for o. aegyptiaca resistance. tomato yield reduction, dry weight reduction of shoot and root,...

This paper uses an example of small-scale, labour-intensive tomato production that is expected to lead to short-term capital accumulation to explore the prospects of engaging rural youth in the agri-food sector in Africa. The data cover one village, Pamdu, located in Brong Ahafo, Ghana where the authors completed their main research in1998/9 and a brief revisit in 2011. Although tomatoes were p...

bulk tomato paste which is produced by most domestic factories in cocentrations more than 35% (35-40 degree of brix), and filled in to barels as bulk quantity under non - hermetic conditions.the microbial contamination level in this product is high since there is no any post heat treatment. for sterilization and microbial redaction barels maybe stored at coldstore or ambient temperatures for mo...

Climate change will bring more drought periods that will have an impact on the irrigation practices of some crops like tomato, from standard water regime to deficit irrigation. This will promote changes in plant metabolism and alter their interactions with biotic stressors. We have tested if mild or moderate drought-stressed tomato plants (simulating deficit irrigation) have an effect on the bi...

Dodders (Cuscuta spp.) are holoparasitic plants that enwind stems of host plants and penetrate those by haustoria to connect to the vascular bundles. Having a broad host plant spectrum, Cuscuta spp infect nearly all dicot plants - only cultivated tomato as one exception is mounting an active defense specifically against C. reflexa. In a recent work we identified a pattern recognition receptor o...
