“…CAP agri-environmental conservation measures have a low level of take-up by farmers, and the most common reasons for the lack of interest are bureaucratic difficulties in accessing calls for tender, low profitability, and a general reluctance to leave the farm's comfort zone [ 37 ]; There is, therefore a need for regular and systematic communication and training of farmers on the content and aims of European, national and regional policies on agriculture, food, and the environment and to accompany them in the transition to environmentally sustainable agriculture, extending the task of training and consultancy to professionals with multidisciplinary skills [ 38 ].…”

“…In 2022, 69,605 ha of nopal were cultivated, of which 45,033 ha produced 444,080 tons of tuna, and 24,571 ha were used to produce nopalitos and forage [4]. The second country in the area cultivated with cactus pear is Italy, with 8300 ha producing 87,000 t [5].…”

The fruits of the nopal (Opuntia spp.), cactus pears, are considered functional foods due to their content of nutritive and bioactive substances. Its pulp is generated by numerous seeds that limit their consumption due to their size and hardness and detract from their quality. Other undesirable fruit characteristics are its inedible peel and its short shelf life. In the case of the cactus pear cactus (Opuntia spp.), no cultivar has been reported that produces quality parthenocarpic fruits, nor have they been obtained by artificially inducing parthenocarpy. The objectives of this research were to evaluate the response of 11 genotypes to the induction of parthenocarpy, to characterize the fruits of the genotypes with the best response, and to determine their postharvest life. To induce parthenocarpy, floral buds were used in the pre-anthesis stage, from which the style-stigma, stamens, and tepals were removed, generating a cavity in which a solution of growth regulators was applied (250 mg L−1 AG3 + 75 mg L −1 BA + 15 mg L−1 of AIB). A similar number of buds was used as a control, without treatment, and in free pollination. Only two genotypes, MX CP-30 Red and MX CP-40 Yellow, produced parthenocarpic fruits since their empty integuments produced pulp, remaining small, empty, and soft. Their peel was sweet (10–14 °Brix) and edible, and they had a longer shelf life than the corresponding fruits with seeds.

“…In recent years, a number of representative early maturing cultivars have been bred, such as 'Sucui 1' and 'Cuiyu' from China, 'Starkimson' of America, 'Madeleine' of France, Plants 2023, 12, 4120 2 of 13 'Samlitoto' of Italy, etc. [4,[6][7][8]. Compared to late-maturing cultivars, embryos from early maturing cultivars have shorter fruit development periods and a lower seed viability and are less mature [9].…”

Breeding early maturing cultivars is one of the most important objectives in pear breeding. Very early maturing pears provide an excellent parental material for crossing, but the immature embryo and low seed germination of their hybrid progenies often limit the selection and breeding of new early maturing pear cultivars. In this study, we choose a very early maturing pear cultivar ‘Pearl Pear’ as the study object and investigate the effects of cold stratification, the culture medium, and the seed coat on the germination and growth of early maturing pear seeds. Our results show that cold stratification (4 °C) treatment could significantly improve the germination rates of early maturing pear seeds. A total of 100 days of cold-temperature treatment in 4 °C and in vitro germination on White medium increased the germination rate to 84.54%. We also observed that seed coat removal improved the germination of early maturing pear seeds, with middle seed coat removal representing the optimal method, with a high germination rate and low contamination. The results of our study led to the establishment of an improved protocol for the germination of early maturing pear, which will greatly facilitate the breeding of new very early maturing pear cultivars.
