A New Technique

Algeria’s date palm (Phoenix dactylifera L) fruit is one of the most important exported products from non hydrocarbon sources. As other fresh or dry fruits, the dates (cv. Deglet Nour) are exposed to damage during storage. In our study, we will apply a postharvest treatment using a radiofrequency radiation as a new technique used on dates while evaluating its effect on date palm fruit quality. The results obtained reveal that the treatment was effective on the capacity of dates to maintain their pH, moisture content and ash percentage during the storage compared with the dates untreated. Likewise, it achieved complete disinfection of dates. As results, the radiofrequency presents a practical alternative to the actually techniques used on postharvest treatment.

El manejo de la polinización en el cultivo de palma datilera, es un proceso clave en el éxito de la cosecha de dátiles. El presente trabajo es una revisión de las técnicas más comunes tanto de extracción de polen, como de polinización en la palma datilera (Phoenix dactylifera L.). Asimismo se hace un análisis de la influencia de las fuentes de polen de los cultivares Deglet Noor, Khadrawy, Medjool y Zahidi sobre la calidad física y nutricional del dátil cultivar Medjool en México, donde se muestra que el uso de polen de machos criollos derivados de la variedad Khadrawy inducen mayor peso de fruto y semilla, así como mayor contenido de azucares, minerales y fenoles.

This study was carried out during three successive seasons 2011, 2012 and 2013 at a private orchard located in Al- Hello in Ajman Emirate (UAE). The experiment was designed to study the effect of organic manure and NPKS as soil application on yield, fruit quality, and fruit mineral nutrient content of Khenazi date palm cultivar grown in sandy soil. Fertilization treatments consisted of N1, 600g or N2, 1000g (urea 46%N), P 800g (triple superphosphate, 48% P2O5), K 1200g (potassium sulphate, 50% K2SO4) and S 700g sulphur (90% granular S), in addition to organic manure. Al experimental trees received 100g mixture of micronutrients, with the exception of the control. The results showed that combination treatments and organic manure significantly affected fruit weight, flesh weight, fruit volume, moisture content and fruit TSS. Application of different fertilization treatments significantly affected yield components of fruit, number of fruits/strand, fruit number/bunch, fruit set percent and total fruit yield / palm. The study revealed that combination of fertilizers improved fruit nutrient content of N, P, K, Ca, Mg, Fe, Zn, Mn and Cu. Moisture and TSS% content, number of fruits/strand, number of fruits/bunch, fruit nutrients content of Fe, Mn and Zn were significantly different due to the application of N1+K+S.
