Summary. — Gibberellic acid at a concentration of 10-3 moles per litre leads to an increase in respiratory gas exchange in fragmented tissues of Solanum tuberosum tubers. Hormone intervention in respiratory cycles is analysed both by the application of effectors leading to the assumption of glycolys...

Pot experiments were conducted to study the effects of straw application of three hyperaccumulator plants (Solanum nigrum, Bidens pilosa and Galinsoga parviflora) influence photosynthetic pigments content and photosynthetic parameters of lettuce (Lactuca sativa) under Cd stress. The results showed t...

Four types of tomatoes (grapes, cherry, cocktail, and cap), produced under greenhouse, were assessed at quantitative level (10 variables). The data show wide variability between types of tomato in terms of age at start of harvest (64.8-76.5 days after transplantation), number of fruits per bunch (4....

[ES] Improvement of cultivated species is a dynamic area, subject to the needs and requirements of the different crops at any given time and to the requirements of producers and consumers. A limitation in this improvement process is the existing genetic diversity in crops, due to population bottlene...

International audience Recently, a lot of interest has been paid on the usage of hyperspectral imaging (HSI) as a technique to evaluate the quality of industrially processed food products. Ecologically grown food products usually have larger prices thus the consumers may expect more sophisticated so...

The interactions of plants with pathogens and beneficial micro-organisms have been seldom compared on the same host and under strict controlled autotrophic in vitro culture conditions. Here, the life cycle of two plant beneficial (Glomus sp. MUCL 41833 and Trichoderma harzianum) and one plant pathog...

[ES] Control of flowering and fructification in species of agronomic interest has raised the interest of plant breeders and plant breeders for years due to the economic impact and social importance of this type of plant. Tomato is one of the most important horticultural species in the world, so our...

4-keto steroidal alkaloids are C-27 substances that have a C-4 carbonyl on their steroidal frame, which makes them different from other steroidal alkaloids. Thus far they have only been found in two South American Solanum trees, which contain them in berries, leaves and roots. The most abundant alk...

RESUMO: The use of water resistance inducers in plants is being studied as an important tool for increasing productivity in agricultural crops. The tomato, Solanum lycopersicum L., is highly relevant among the horticultural sectors, both in economic and social terms, because of their large volume of...

Abstract Plant root systems are exposed to spatial and temporal heterogeneity regarding water availability. In the long‐term, compensation, increased uptake by roots in areas with favorable conditions in response to decreased uptake in areas under stress, is driven by root growth and distribution. I...

La growing public concern about the negative effects of agricultural activities on the environment has led to more sustainable crop production, especially in fertilisation management. Composta is an organic fertiliser used as a source of nutrients and as a constituent of substrates in protected agri...

El present work was carried out at the Microbiology Laboratory of the Faculty of Agricultural Sciences belonging to the University of Ciego de Ávila ‘Máximo Gómez Báez’. The study material was potatoes of the Santana variety from the Various Crops Company ‘La Cuba’. Four experiments were set up in t...

An assessment of the growth of seedlings of five potato cultivars, propagated from sharps and media in the presence of white light, is made to determine the quality of the seedlings. Atlantic and Fianna cultivars were more adapted to the hydroponic system due to greater stem thickness and abundant r...

The accumulation of some essential (copper, manganese and zinc) and toxic metals (lead and cadmium) in cultivated vegetables - Brassica oleracea (cabbage), Daucus carota (carrot), Allium cepa (onion), Spinacia oleracea(spinach) and Solanum lycopersicum (tomato) - was examined. The vegetables were lo...

: Ammonium (NH4 ) and nitrate (NO3 —) are the two main forms of nitrogêum that can be absorbed by most plants, depending on environmental conditions. An experation in vegetation casks was conducted with the aim of assessing the effect of different NO3 —/NH  4 relationships on the development and c...

An aqueous crude extract from Solanum nigrum lyophilized leaves was evaluated for its phytochemical composition and antifungal activity against Penicillium digitatum, the causative agent of green mold of citrus fruit. Phytochemical analysis of the extract revealed the presence of some bioactive subs...

<p>In South Africa the invasion of riparian forests by alien trees has the potential to affect the country's limited water resources. Tree water-use measurements have therefore become an important component of recent hydrological studies. It is difficult for South African government initiatives, suc...
