Novel subpopulations in date palm (Phoenix dactylifera) identified by population-wide organellar genome sequencing
2019
Background The date palm is one of the oldest cultivated fruit trees. The tree can withstand high temperatures and low water and the fruit can be stored dry offering nutrition across the year. The first region of cultivation is believed to be near modern day Iraq, however, where and if the date palm was domesticated is still a topic of debate. Recent studies of chloroplast and genomic DNA revealed two major subpopulations of cultivars centered in both the Eastern range of date palm cultivation including Arabian Peninsula, Iraq and parts of South Asia, and the Western range, including North Africa. Results To better understand the origins of date palm cultivation we sequenced and analyzed ov…
Two polyhydroxystilbenes from stems of Phoenix dactylifera
1983
Abstract From stems of Phoenix dactylifera trans-3,5,3′,5′-tetrahydroxy-4-methoxystilbene has been isolated as a major component; cis-3,5,3′,5′-tetrahydroxy-4-methoxystilbene and trans-3,5,4′-trihydroxystilbene were isolated as minor components. Other metabolites from the biogenetic route to these stilbenes were also characterized.

La cattura di adulti del Punteruolo rosso delle palme con trappole a feromone e allomoni in ambiente urbano
2010
In questo lavoro sono presentati i risultati di un anno di catture di adulti di Punteruolo rosso delle palme, Rhynchophorus ferrugineus (Olivier), con trappole a feromone e allomoni collocate nel comune di Marsala (TP). In totale sono state sistemate 47 trappole ad una distanza media di circa 200 m. Le trappole sono state innescate con feromone di aggregazione (ferrorule), acetato di etile (10 % /H2O), e melassa (10 % /H2O), ed ispezionate settimanalmente per il periodo aprile 2008 – aprile 2009. Le trappole sono state disposte lungo la costa della città(N=21), e lungo una linea che attraversa il centro cittadino (N=26). In totale sono stati catturati 4010 adulti, con un numero complessivo …
