Production Characteristics

This study was aimed at observing the effect of the grafting of tomato plants on morphological (vegetative growth), production and nutritive characteristics (quantity and quality of production). For this purpose, the ‘Lorely F1’ cultivar was used as a scion grafted onto the ‘Beaufort’ rootstock. Plants were cultivated with a stem and two stems. The observations collected in this study were concerned with the characteristics of plant growth. The studied morphological characteristics were plant height, stem diameter and number of leaves, and the studied production characteristics were the characteristics of fructification and productivity (the average number of fruit per plant, the average weight of the fruit, production per plant). Particular attention was paid to the nutritional characteristics of the fruit, to the fruit quality (total soluble solids, total sugar, acidity, vitamin C, antioxidant activity (by the Trolox method) and the contents of lycopene and beta-carotene). The results showed that grafting positively influenced the growth and production characteristics. Grafting of tomato plants had an appreciable effect on the vegetative growth of the variant 2-grafted tomatoes with a stem. The best option in terms of productivity and production was the variant 3-grafted tomatoes with two stems, which yielded 9.2 kg per plant. Fruit quality was not improved in any of the grafted variants.

The production of grafted passion fruit is an alternative for plant adaptation to saline environments. The objective of this study was to evaluate the effect of salt stress on physiology, biometry and fruit quality of P. edulis grafted on Passiflora spp. The experiment was conducted in completely randomized design, in a 3 x 2 factorial scheme, corresponding to three species of Passiflora (P. edulis, P. gibertii and P. cincinnata) with P. edulis scion and two levels of irrigation water salinity (0.5 - control and 4.5 dS m-1), with four repetitions. Water salinity compromises gas exchanges (CO2 assimilation raste and transpiration) and physiological variables (total chlorophyll and total water consumption) in grafted P. edulis. The interaction between the factors (water salinity x species) compromised only the growth in plant height and number of leaves. In relation to the species, auto-grafted P. edulis stood out from the other species, with higher internal CO2 concentration, number of leaves, stem dry mass, peel thickness, total soluble solids (TSS) of the pulp and TSS/TA ratio (titratable acidity). Auto-grafted P. edulis under saline conditions develops vital mechanisms (TSS and TSS/TA), which attenuates the effects of salt stress on the physico-chemical quality of the fruits.

Background: Seaweed-derived extracts have gained popularity in agriculture as bioproducts with phytostimulatory effects on plant growth and development. Methods: This study assessed the effect of polysaccharide-enriched extracts (PEEs) derived from six Moroccan seaweeds on tomato growth, yield, and fruit quality. PPEs were applied to tomato plants as soil drench in a greenhouse experiment. Growth parameters including plant height (cm) and number of leaves, flowers, and flower buds were recorded every 15 days. Yield and quality parameters of the harvested fruits were also recorded after each harvest. Results: The obtained results showed that all PEEs improved the growth, yield, and fruit quality of treated tomato plants. According to principal component analysis, the presence of SO4, galactose, glucose, and maltose in the characterized polysaccharides was closely associated with their effect on plant growth, yield, and fruit quality parameters. Conclusions: PEEs obtained from Gelidium crinale,Schizymenia dubyi, Fucus spiralis, and Bifurcaria bifurcata exhibited the highest biostimulant effects and could be used as bioproducts for improved tomato yield and fruit nutritional quality.

Soilless Culture

Salt stress is known as one of the most severe abiotic factors limiting the plant production all over the world. In this study, three additives: (i) supplemental Ca (5 mmol L–1) to nutrient solution, (ii) foliar application of micronutrients (Fe, Mn and Zn at 60, 160 and 110 mg L–1, respectively), and (iii) combination of both of them were evaluated aiming to reduce the negative impact of salt stress on tomato plants cultivated in a soilless culture and improve the internal quality of fruits. The obtained results show that salinity reduced vegetative growth and physiological parameters, fruit yield and its components, and even more lowered fruit market classification of tomatoes. Salinity treatment reduced most of essential macro- and micronutrients in tomato fruit, whilst Na content was increased. Tomato productivity and fruit quality were ameliorated under saline conditions by increasing Ca into nutrient solution and applying a foliar application of micronutrients. A com- bination of both additives ranked the first to alleviate the adverse effects of salinity on tomatoes, followed by solo supplemental Ca into saline nutrient solution. On the other hand, the internal fruit quality of antioxidant compounds, such as vitamin C, lycopene, α-carotene, β-carotene and lutein as well as acidity, total soluble solid and dry matter percent, were increased under saline conditions.

In the past few years, there has been a high demand for the use of new generations of biological products in modern agriculture. Several of these products are friendly to the environment and guarantee good yield and quality of many horticultural products. Pesticide residues resulting from heavy applications of a wide range of chemicals to control various pests is becoming a serious problem for exports, as well as for local consumption, of many products. This study was initiated to examine the effect of Ret-flo Px-357 a biological compound from EIBOL Co., Spain, developed to induce resistance to nematode infestation on several plants. `Daniella' tomato and `Grande naine' banana grown in plastic greenhouses were used to evaluate these effects. Two ground applications of Px357 at the rate of 20 L·ha–1 were used at 4-month intervals in Oct. 1996 and Feb. 1997. These treatments have stimulated root formation, stem diameter, and plant height. In tomato plants, the number of flowers and fruits per cluster was greater in treated than in non-treated plants. After harvesting eight clusters from the tomatoes, the number, size, individual fruit weight and total production of fruits from treated plants were greater than for the control plants. Similar results were observed in banana plants, which showed larger pseudo-stem and heavier fruit bunches at harvest. Variation in nematode population as well as plant nutrition during plant growth will be discussed, and results related to fruit quality will be presented and commented upon.
