The effects of commercial vermicomposts, produced from food waste, on infestations and damage by aphids, mealy bugs and cabbage white caterpillars were studied in the greenhouse. Vermicomposts were used at substitution rates into a soil-less plant growth medium, MetroMix 360 (MM360), at rates of 100% MM360 and 0% vermicompost, 80% MM360 and 20% vermicompost, and 60% MM360 and 40% vermicompost t...

effects of water stress and fusarium oxysporum f. sp. lycoperseci (fol) on the growth of tomatoes were studied in a greenhouse experiment. treatments consisted of five levels of water stress (1, 3, 5, 7 and 9 day irrigation intervals). infested soil consisting of 400 chlamydospores g1 of fol and non infested soil were used. experiments arranged in a completely randomized design with 8 replicati...

Ceratothripoides claratris Shumsher is one of themost important thrips pest of tomatoes in central Thailand. Hence we conducted studies to determine the intraand inter-plant distribution of C. claratris on tomatoes in two types of greenhouses, i.e., open-plastic and closed net house. The experimentswereconductedon thecampusof theAsian InstituteofTechnology inBangkok,Thailand. Both adults and la...

Seedling vigor in tomatoes determines the quality and growth of fruits and total plant productivity. It is well known that the salient effects of environmental stresses appear on the internode length; the length between adjoining main stem node (henceforth called node). In this study, we develop a method for internode length estimation using image processing technology. The proposed method cons...

The tomato rbcS gene family is composed of five genes (rbcS1, 2, 3A, 3B, and 3C) that are differentially expressed during tomato development. Nuclear run-on transcription assays and RNA analysis were used to determine the contribution of transcriptional and post-transcriptional regulation to the accumulation of mRNA from the five rbcS genes in tomato seedlings, leaves, and fruit. We found that ...

Tomato bacterial wilt caused by Ralstonia solanacearum bacterium is a severe problem in Southern China, where relatively high environmental temperatures commonly prevails during the crop seasons. Previous research has indicated that bacterial wilt disease incidence generally increases during the warm months of summer leading to reduced tomato yield. Moreover, the efficacy of bio-organic fertili...

In this study, the effects of tomato (Solanum Lycopersicum cv. Depar F1) seedlings grafted on three different rootstocks (Kudret, Hamarat, Pençe) yield and some quality parameters plants grown in greenhouse open field were investigated. According to results we obtained, while greenhouses grew up 42.3% faster than those open, an increase was achieved by 265%. While TA vitamin C values, among fru...

Seedlings of aubergine (Solanum melongena L.) cv. ‘Rima’ were used as scion (R) and control (non-grafted) and rootstock (self-grafted) (RR), while two hybrid tomatoes ‘Heman’ (Lycopersicon hirsutm) and ‘Primavera’ (Lycopersicon esculentum) were used as rootstocks. Grafted and non-grafted plants were grown in the greenhouse and in the open-field. Grafted plants Rima and Heman (RH) were more vigo...

Tomato, Lycopersicon esculentum Mill is a vegetable crop of large importance throughout the world. Its annual production accounts for 107 million metric tons with fresh market tomato representing 72 % of the total (FAO, 2002). It is the first horticultural crop in Tunisia with a production area of 25,000 hectares and a total harvest of 1.1 million metric tons (DGPA, 2009) of which nearly 70 % a...

It is known that the use of resistant cultivars and mineral nutrition associated with humic substances, such as fulvic acids, can favor plant development, promoting aerial parts roots growth, being a viable technique for better vegetative development plants in general, and, consequently, final productivity. The aim this work was to evaluate effect fertilizer Bio Humate®, based on Justyne® hybri...
