Studies of salute plenetration into living cells are becoming legion. Protective or barrier membranes must be traversed1. Cell particulates, cells themselves. and external plant surfaces are covered with membranes of varying permeabilities. Not the least among the membranes are the noncellular cuticles that cover all aerial plant parts including leaves. Absorption by living leaf cells of any fo...

Fruit ripening in tomato (Solanum lycopersicum) is a complicated development process affected by both endogenous hormonal and genetic regulators and external signals. Although the role of NOR, a member of the NAC domain family, in mediating tomato fruit ripening has been established, its underlying molecular mechanisms remain unclear. To explore further the role of NAC transcription factors in ...

To evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. In this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

this study was conducted to investigate the effects of irrigation frequency and substrates on some parameters of greenhouse tomato (cv. hamra) during 1381-1382 at research greenhouse of agriculture college, in ferdowsi university of mashhad. the experiment was based on split plots in the form of completely randomized design and in four replications. irrigation frequency in three levels of 12, 8...

Fruit ripening is a complex and genetically programmed process. Brassinosteroids (BRs) play an essential role in plant growth and development, including fruit ripening. As a central component of BR signaling, the transcription factor BZR1 is involved in fruit development in tomato. However, the transcriptional network through which BZR1 regulates fruit ripening is mostly unknown. In this study,...

tomato (solanum lycopersicum l.) is one of the most important vegetable plants in the world. it originated in western south america, and domestication is thought to have occurred in central america. in order to study the effect of polyethylene sheet as mulch on water requirement and yield of tomato, an experiment was carried out as factorial layout based on a randomized complete block design wi...

In August 2021, symptoms of a viral-like infection were observed on the leaves and fruits tomato plants, cvs. Emperador RZF1 (Rijk Zwaan, The Netherlands) Maxifort, Eshkol 4129 (Seminis Vegetable Seeds, USA) in 3.2 ha greenhouse complex Isfahan province, Iran. Plants had been raised Iran from imported seed. consisted severe mosaic deformation (especially upper young leaves) chlorotic brown necr...

Ethylene is a gaseous plant hormone controlling fruit ripening, flower opening, leaf senescence as well as abscission, and disease symptom development. Ethylene plays a critical role in the bacterial pathogen Xanthomonas euvesicatoria (X. euvesicatoria)-elicited symptom development in tomato. This protocol describes the measurement of ethylene gas produced by tomato leaves infected with X. euve...

Tomato production in the Mediterranean region and elsewhere is under constant threat of the whitefly-transmitted begomoviruses that cause Tomato yellow leaf curl disease (TYLCD). Sequencing has indicated that the generic ‘TYLCV’ includes a large number of viruses and strains. We studied the distribution of the tomato yellow leaf curl disease-associated viruses in Egypt, Israel, Jordan and Leban...

tomato production, growing nearly 40 percent of world supply. The majority of fruit is processed into concentrated paste, but an increasing percentage is being used for products utilizing peeled fruit, either whole or diced. Important fruit quality attributes for paste production are soluble solids content (SS) and color of the blended product. Uniformity of color is more important for peeled f...
