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.

Pumpkin Seed

Cucurbita pepo var. styriaca is known as a medicinal crop among other cucurbits. The benefits of cucurbits fruits are very important in terms of human health, purification of blood, removal of constipation, digestion and supplying energy. The mutant styrian oil-pumpkin (Cucurbita pepo L. convar. Pepo var. styriaca Greb.) exposes a complete lack of lignification of the seed testa. For this reason, this kind of naked pumpkin seed is more consumable as snack than other seeds. The vegetative growth of plants is crucial for fruit production. Nitrogen is the most imperative element for the proper vegetative growth and development of plants which significantly increases and enhances yield and its quality by playing a vital role in the biochemical and physiological functions of plants. Field studies were conducted to study the effect of nitrogen nutrition on certain physiological parameters and their differences between the styrian oil pumpkin hybrid and cultivar (Gleisdorfi Classic cultivar and GL Rustical hybrid). The small block experiment was carried out based on a factorial experiment with a completely randomised block design and four replications in the Research Institute of Nyíregyháza during the summer period of 2017 and 2018. Three different concentrations of nitrogen fertiliser was applied at sowing. Photosynthetic pigments (chlorophyll-a, -b and carotenoids) were analysed as one of the basic factor of efficient photosynthesis. The yields of two genotypes were also measured in all treatments as seed-weight. The contents of photosynthetic pigments were higher in the oil-pumpkin hybrid, mainly the carotenoids in 2018. The vegetation period of 2018 was drier than in 2017, the hybrid oil-pupmkin was more efficient in stress tolerance than the cultivar with higher carotenoids pool. The obtained yield was more pronounced in the oil-pumpkin hybrid than the cultivar in all examined years. The hybrid GL Rustical was more sensitive to nitrogen treatment than the cultivar Gleisdorfi Classic.

Preliminary Study

The present paper studies the growth and fruiting processes of two Aronia melanocarpa cultivars, ‘Melrom’ and ‘Nero’, in the pedo-climatic conditions of the Muntenia (Arges) area, Romania. On average, over the whole experience, the ‘Merlom’ cultivar recorded a bush volume of 0.72 m3, annual vegetative growth of 0.38 m3, productivity of 1.88 kg of fruit per plant, and a ratio between fruit yield and the annual vegetative growth of 6.54 kg/m3. In the ‘Nero’ cv., the volume occupied by the aerial part of the bush was 1.98 m3, with an annual vegetative growth of 0.43 m3, an yield of 3.14 kg of fruits per plant, and, reported to the annual vegetative, fruit production was 10.64 kg/m3. Although the volume of the aerial part of the plant and the fruit production per plant were significantly higher in ‘Nero’ cultivar, ‘Melrom’ was noted by a larger ratio of fruit production to the unit volume of the aerial part of the plant, of 3.28 kg/m3. As resulted from our study, both cultivars presented valuable yielding potential.

Different Doses

The necessity of controlling the vegetative growth of fruit trees is a growing concern for farmers since vigorous plants tend to have lower fruit yields. The use of chemicals that inhibit the vegetative growth of plants, such as prohexadione-calcium (PCa), an inhibitor of gibberellins which is currently used as a growth regulator for apple trees, is an agricultural practice aimed to help in reducing pruning time and cost. Pear trees grafted on vigorous rootstocks tend to present high rates of vegetative growth, hindering fruit production. Thus, this work aimed to evaluate the effect of the application of different doses of the plant growth regulator PCa on the vegetative growth, pruning time, radiation incidence, and productive and quality parameters of ‘Packham’s Triumph’ and ‘Hosui’ pears grafted on vigorous rootstocks. Two PCa applications were carried out, the first after the falling of petals (2009-10-10), and the second twenty-one days after the first (2009-11-02). The observed results showed a significant effect of PCa in reducing the vegetative growth of the pear trees and the pruning time in both cultivars. The effect on photosynthetic active radiation (PAR) was observed only in the ‘Packham’s Triumph’ variety, not being observed for the ‘Hosui’ pear trees. No statistical difference was observed relative to the quality parameters and yield of the fruits, in both cultivars, showing that PCa application has not caused any deleterious effect on fruit development.

Sequence Effects

Any mineral nutrient deficiency or toxicity that adversely influences the normal biochemical and physiological processes in the tree can be expected to impact regularity of cropping. Deficiency of N limits growth and flowering of young trees and increases potential for biennial bearing in mature trees while excess N may stimulate excessive vegetative growth that results in shading of spurs and development of weak flowers with reduced set potential. B, Zn, and Cu shortages influence regularity of cropping through effects on flower development, pollination and/or fertilization. Effects of K, Mg, Mn, Fe, or S appear to be indirect, principally as consequences of limited carbohydrate production/availability. Crop load/vegetative growth relationships in one season can exert significant influences on nutrient status within the tree that may influence potential for cropping in the next season. Environmental stress may limit nutrient availability of various nutrient elements at critical times during the flower development and fruit setting sequence. Effects of nutritional factors on regularity of cropping must be considered in relation to their interaction with all other components of the fruit production system. Maintaining appropriate essential mineral nutrient supply and availability to avoid potential deficiencies or toxicities is critical to regular cropping of apple trees.
