Alstroemeria: a charming genus. Repositório Alice
SANSO, A. M.; ASSIS, M. C. de; XIFREDA, C. C..
Alstroemeria (Alstroemeriaceae), the Incas lily, an exclusively South American genus comprises near 90 species ranging from Venezuela (3° North) to Tierra del Fuego, Argentina (53° South). Alstroemeria species and hybrids have gained world-wide importance as cut flower crop due to its attractive flowers and the excellent keeping quality of them. Nevertheless, they are also suitable for growing in pots and for garden and landscape uses. The recent taxonomic revisions of the group for Brazil (Assis, 2001), Argentina (Sanso, 1996), and Chile (Bayer, 1987), the biosystematic research (Aagesen and Sanso, 2003; Sanso and Xifreda, 1998, 1999, 2001, 2003) and the chromosome studies (Sanso and Hunziker, 1998; Sanso, 2002) have facilitated the identification of the...

Capdeville,Guy de; Maffia,Luiz A.; Finger,Fernando L.; Batista,Ulisses G..
Gray mold of roses (Rosa hibrida) caused by Botrytis cinerea requires many management strategies for its control. The effect of pulsing rose cv. Kiss with solutions of citric acid, salicylic acid, sucrose, calcium sulfate, and silver thiosulfate (STS) on disease severity and vase life of the flowers was evaluated. The solutions were applied to cut stems at different stages of harvest, the variation in the opening stage of harvest did not affect the results. Pulsing with STS reduced the values of area under the disease progress curve (AUDPC) and of severity of disease by 15% and 55%, respectively, and increased the vase life of the flowers by 20%. Calcium sulfate consistently reduced AUDPC by 66% and maximum severity by 88%, and increased vase life of the...

Mattiuz,Claudia Fabrino Machado; Mattiuz,Ben-Hur; Rodrigues,Teresinha de Jesus Deléo; Pietro,Júlia de; Martins,Ramilo Nogueira; Grossi,Selma de Fátima.
Oncidium varicosum belongs to Orchidaceae family and nowadays it is commercialized on large scale due to its potential as cut flower. The species distinguishes decoratively in function of the high number of flowers golden yellow that compose its great and delicate inflorescence. The hormone ethylene performs an important function in the processes related with the senescence of cut flowers, and especially in relation to orchids anti-ethylene treatments are recommended to extend the vase life. Among chemicals used today for the postharvest treatment of flowers the 1-methylciclopropene (1-MCP) is an efficient inhibitor of autocatalytic production of ethylene. This research aimed to evaluate the effect of different concentrations of 1-methylciclopropene...

Non-tariff Barriers to Trade Caused by SPS Measures and Customs Procedures with Product Quality Changes AgEcon
Liu, Lan; Yue, Chengyan.
This study develops a methodology to quantify the combined effects of two major nontariff barriers (NTBs), sanitary and phytosanitary (SPS) measures and customs and administrative procedures. We employ a constant elasticity of substitution (CES) utility function with factor-augmenting technical progress to incorporate changes in the quality of goods. We then estimate the effects of these two NTBs in the Japanese cut flower market. Results show that estimates of SPS are biased without considering product quality changes caused by the customs and administrative procedures for highly perishable agricultural products. If these Japanese NTBs were removed, findings suggest there would be a significant increase in cut flower imports by Japan.

Preservative solutions on quality and biochemical aspects of calla lily flowers Ciência e Agrotecnologia
Sales,Thais Silva; Paiva,Patrícia Duarte Oliveira; Siqueira,Heloísa Helena de; Manfredini,Guilherme Mariano; Lima,Luiz Carlos de Oliveira.
ABSTRACT The knowledge of physiological and biochemical aspects occurring at the postharvest phase of flowers is critical to guide efficient conservation techniques for maintaining quality and longevity. Factors that cause deterioration of cut flowers after harvest are dehydration, low carbohydrate contents, the presence of microorganisms in vase solution or stem and late stage of development at harvest. Thus, the objective was to determine the effect of harvest stages of calla lily stems and storage solutions on water relations and contents of starch and sugars. Flower stems were harvested in the following opening stages of the spathe: early-stage (cartridge) and 1/3 open and were arranged in six storage solutions containing 1, 2, 4 and 6% glucose and the...

Violence, Political Instability, and International Trade: Evidence from Kenya’s Cut Flower Sector AgEcon
Muhammad, Andrew; D'Souza, Anna; Amponsah, William A..
Abstract: We assess whether and how violence and political instability affect trade between developed and developing countries considering the special case of EU imports of Kenyan roses after the 2007/08 post-election violence and political instability in Kenya. Using the Rotterdam model to estimate EU demand for roses from Kenya and other global competitors, we find evidence of a structural change in the import growth rate for Kenya, approximately equivalent to an 18.6% tariff. These results highlight the importance of non-tariff barriers to trade and contribute to the growing literature on the role of insecurity and instability in hindering international trade.
