“…According to Kulczynski and Gramza (2019), there is a region/climate correlation effect on this mineral in pumpkins. Some authors report significant concentrations of β-carotene and α-carotene in pumpkin pulp (Rodríguez et al, 2018;Valdés et al, 2014). Also report β-carotene concentrations in C.pepo and C.mochata between 4.58±2.27 and 2.92±1.44 mg 100 -1 g -1 o.d, respectively (Kulczynski and Gramza, 2019).…”

“…For the year 2018, in the department of Antioquia, the harvested area was 100 ha, with a production of 1200 t and a yield of 12.0 t ha -1 , being the municipality of Dabeiba the largest producer with 65 ha cultivated (Agronet, 2018). Its importance in the diet has generated interest in improving it genetically, achieving better yields, and in the quality of the pulp (Valdés et al, 2014).…”

Pumpkin (Cucurbita maxima), also called squash is a mass consumption fruit used in agroindustrial transformations to obtain new food products. This study aimed to evaluate the physical, physiological and physicochemical properties during a storage period of 42 days and the nutritional compounds of the freshly harvested fruit fractions. According to the CIEL*a*b* space, both the pulp and peel did not present significant changes in L* and a* values during the evaluated storage time; however, in the peel, a change in the b* values was evidenced. In addition, there was a decrease in the firmness of 10.8% in the fruit with peel and in the pulp, it was of 19.8% was observed, with a whole fruit weight loss of 2.33% and an average respiration rate of 6.9 mg CO2 kg-1h-1. According to physicochemical characteristics evaluated in the pulp, the values of pH, percentage of humidity, acidity, water activity and total soluble solids had no statistically significant changes occurred during the storage time. At the nutritional level, pumpkin is a good source of minerals, with a high concentration of potassium in all its fractions, and also has in total carotenoids (4.11±1.6 mg of β-carotene g-1 oven dry (o.d) in pulp and 6.24±2.7 mg of β-carotene g-1 (o.d) in peel). It was possible to conclude that the pumpkin has a low respiration rate, maintaining its physicochemical characteristics suitable for consumption throughout the evaluation period, presenting suitable conditions.

The Environmental-Economic Performance of a Poblano Family Milpa System: An Emergy Evaluation

et al. 2021

View full text Add to dashboard Cite

The family milpa system (FMS) is of great importance to food security and the livelihoods of rural families in Mexico. However, the performance of the system can be compromised due to inappropriate agricultural practices. Therefore, a suitable evaluation strategy is required to identify the best management of resources. Nonetheless, at present, there is no holistic understanding around the nature–society interface that allows us to predict the global behavior of the FMS. Thus, this study assesses the global performance of a Poblano FMS through emergy-based indices. The emergy evaluation was carried out by accounting for the available energy of different qualities used in the system, which were subsequently converted to one kind of energy (solar emjoules). The percentage of renewable emergy (%Ren) used in the system was 72.16%. The emergy self-support ratio (ESR) showed that 74% of the emergy used came from free local resources. The emergy investment ratio (EIR) of 0.36 indicated that the emergy use was efficient. The emergy yield ratio (EYR) was 3.78, which in terms of net emergy (NE), was equivalent to a gain of 1.35 × 1016 sej ha−1 y−1. The environmental loading ratio (ELR) was 0.39, which indicated a low potential environmental impact. The emergy sustainability index (ESI) was high (9.80) compared to other agricultural systems. The performance of the FMS is superior compared to other agricultural systems, including ecologic and recycling systems. However, the use of resources is not optimum and needs to be improved to reach maximum empower.

Morpho-agronomic assessment of introductions of butternut squash (Cucurbita moschata Duch.) from Central America

A Central American collection of butternut squash (Cucurbita moschata Duch.) was characterized based on a series of morpho-agronomic descriptors and its variability assessed. Floral asynchrony ranging from 10 to 15 days was observed between staminate and pistillate flowers. Differences were also observed among introductions for all quantitative characteristics evaluated (P<0.01). An interaction between introduction and planting cycle (P<0.05) was observed for 50% of the evaluated variables: fruit weight, polar diameter of fruit, wall thickness of fruit, fruit color, days to harvest, and total fruit seed weight. Cluster analysis revealed that groups 3 and 5 gathered introductions presenting high yields and larger, heavier fruits. Group 4 gathered introductions with intermediate yields, high seed production, and thick fruit walls. In all cases, genetic improvement aiming to increase the production of fruit for fresh consumption or agro-industrial purposes as well as the production of oilseed should use introductions from groups 3 and 5 in well-planned crossings with introductions from group 4.
