The plants used for phytoremediation pose special biological risks, whether transgenic or not, as most of the species: (a) are semi-domesticated; (b) are introduced from other habitats; (c) can become established in the contaminated site; (d) can spread and displace native species, and/or; (e) may introgress transgenes into related species. The addition of transgenes can reduce the risks, e.g. ...

An increasing number of intensive, dense, and sustainable citrus plantations have fostered a growing interest in addressing the future challenges crops: increase world’s population, climate change, globalization. Nutrient efficiency absence vigorous rootstocks are required for success these plantation systems. The agronomic performances ‘Lane Late’ orange cultivar on three substandard or semi-d...

With the growing demand for quality food in world, there is a new ambition to produce high-quality apples seeking reduced cultivation costs. The aim of this study was evaluate influence agrotechnological tools on cv. Rubin during harvest. apple tree (Malus domestica Borkh.) grafted dwarfing rootstocks P60, planted single rows spaced 1.25 m between trees and 3.5 rows. Six were used—hand pruning,...

New foreign rootstocks for peaches [Prunus persica (L.) Batsch] are now being introduced into the United States through commercial nurseries for future sales to stone fruit growers. Almost all of these rootstocks are complex Prunus L. hybrids that are propagated vegetatively. Past experience with foreign Prunus rootstocks has shown that extensive testing is critical to avoid potential problems ...

Most fruit-tree breeding projects are based on selection of seedlings in regard to their performance. The selected seedlings are vegetatively propagated, usually by grafting. It is highly important for the breeder to know whether the performance of the grafted tree will resemble the performance of the original seedling. In this study the performance of avocado and mango seedlings was compared w...

Whole-plant hydraulic conductance, shoot growth, and leaf photosynthetic properties were measured on kiwifruit vines with four clonal rootstocks to examine the relationship between plant hydraulic conductance and leaf stomatal conductance (gs) and to test the hypothesis that reduced hydraulic conductance can provide an explanation for reductions in plant vigour caused by rootstocks. The rootsto...
