“…Organic acid, soluble sugars and pigments are important components that may contribute to flavor and nutritional value of vegetables, indicating the quality of these products. However the production system, maturation stage, the environmental temperature (Guevara-Figueroa et al, 2015), incident radiation (Caldwell and Britz, 2006) and soil type (Pinto et al, 2014) may change their chemical characteristcs.…”

The objective of this research was to compare the physical and chemical characteristics and antioxidant activity of organic and conventional carrot (Daucus carota), green pepper (Capsicum annuum) and lettuce (Lactuca sativa). Five representative samples of conventional vegetables, certified organic and non-certified organic vegetables were gotten from farms and supermarkets in the city of Rio de Janeiro. The result shows that the organic carrot showed higher acidity (0.11 g % citric acid) and total sugar (5.68 g %) than those found in standard samples and certified organic ones (p<0.05). Regarding the density analysis and total soluble solids, there was no statistical difference between carrots, green peppers and lettuce from all types (p>0.05). It was observed that the vitamin C levels in carrot samples levels had no significant difference between the different forms of production (p>0.05). Conventional lettuce and certified organic pepper showed higher vitamin C than the other samples (p<0.05). The antioxidant activity of the samples was analysed by the capacity to reduce the DPPH (1,1diphenyl-2-picryl-hydrazyl) radical, in which carrot and conventional pepper showed lower antioxidant activity (p<0.05) when compared to organic samples. There were no significant differences among the different forms of production in the lettuce samples (p>0.05). Carrot and green pepper, with seal certification or not, showed higher capacity to reduce DPPH than the conventional ones, this suggests that the form of cultivation has a direct relationship with the nutritional values of the vegetables.

Abstract-Garlic is a popular crop planted widely around the world, but garlic planting is a heavy work. This paper proposed an automatic machine which can achieve the automation of garlic planting. Based on the study of the main structure of the machine, the connection and transmission relationship of the machine were studied. The function of each main component was introduced in this paper, and the calculation method and steps of the power used to drive the machine were also given. The garlic automatic planting machine has a suitable design, which works in high efficiency, stability and economy.

“…Pre-planting cold treatment and/or winter temperatures significantly affect the developmental regulation and phenotypic expression of growing garlic plants, their bulbing and bulb quality, as well as its reproductive development [7]. Extended vernalization strongly expedite vegetative growth, early meristem transition and bulbing, thus resulting in the development of only a few axillary buds (cloves) and consequently in small bulbs and inflorescences [5,7,26,76,95].…”

Crosstalk in the darkness: bulb vernalization activates meristem transition via circadian rhythm and photoperiodic pathway

Background: Geophytes possess specialized storage organs -bulbs, tubers, corms or rhizomes, which allow their survival during unfovarable periods and provide energy support for sprouting and sexual and vegetative reproduction. Bulbing and flowering of the geophyte depend on the combined effects of the internal and external factors, especially temperature and photoperiod. Many geophytes are extensively used in agriculture, but mechanisms of regulation of their flowering and bulbing are still unclear. Results: Comparative morpho-physiological and transcriptome analyses and quantitative validation of gene expression shed light on the molecular regulation of the responses to vernalization in garlic, a typical bulbous plant. Long dark cold exposure of bulbs is a major cue for flowering and bulbing, and its interactions with the genetic makeup of the individual plant dictate the phenotypic expression during growth stage. Photoperiod signal is not involved in the initial nuclear and metabolic processes, but might play role in the later stages of development, flower stem elongation and bulbing. Vernalization for 12 weeks at 4°C and planting in November resulted in flower initiation under short photoperiod in December-January, and early blooming and bulbing. In contrast, non-vernalized plants did not undergo meristem transition. Comparisons between vernalized and non-vernalized bulbs revealed~14,000 differentially expressed genes.Conclusions: Low temperatures stimulate a large cascades of molecular mechanisms in garlic, and a variety of flowering pathways operate together for the benefit of meristem transition, annual life cycle and viable reproduction results.The circadian clock appears to play a central role in the transition of the meristem from vegetative to reproductive stage in bulbous plant, serving as integrator of the low-temperature signals and the expression of the genes associated with vernalization, photoperiod and meristem transition. The reserved photoperiodic pathway is integrated at an upstream point, possibly by the same receptors. Therefore, in bulb, low temperatures stimulate cascades of developmental mechanisms, and several genetic flowering pathways intermix to achieve successful sexual and vegetative reproduction.
