Date palms (Phoenix dactylifera, Arecaceae) are of great economic and ecological value to the oasis agriculture arid semi-arid areas. However, despite availability a large date palm germplasm spreading from Atlantic shores Southern Asia, improvement species is being hampered by lack information on global genetic diversity population structure. In order contribute varietal provide new insights influence geographic origins human activity structure palm, this study analysed species.Genetic...
Abstract Given the dioecious nature of date palms, selecting an effective pollinizer bearing a substantial quantity high-quality pollen is imperative. In this study, we investigated effects 11 male palm cultivars from Tunisia on production female trees, fruit sets, and characteristics 'Deglet Nour' cultivar dates. The comparison germination rates showed that ABD1 P169 pollens exhibited outstanding viability, with 98.7% 98.3%, respectively. On other hand, had highest rate, at 86.3%. most...
Success artificial pollination with viable pollen is crucial process in the production chain of date palms. This study evaluated impact storage temperature and duration, time following spathe cracking, hour daytime on viability, germinability, fruit set yield 'Deglet Nour' palm cultivar. In vitro tests, fresh showed maximum viability (96.3%) germination (85%) but it decreased thereafter upon (28, 4 -30 °C) duration (3, 6, 9 12 months). this respect, stored at °C retained highest...
Date palms are a vital part of oasis ecosystems and an important source income in arid semi-arid areas. Crossbreeding is limited due to the long juvenile stage date their dioecious nature. The aim this study was create triploid obtain larger seedless fruits increase resilience abiotic stresses. A tetraploid palm mutant crossed with diploid male palm, yielding hundreds seeds suspected containing embryos. Six years after planting, four confirmed triploidy reached maturity. They phenotypically...
Barley (Hordeum vulgare L.) is an important crop in Tunisia, especially the south, which characterized by arid Saharan climate.Water resources, when available, are saline.In this study, 26 barley genotypes were evaluated conditions.Plants irrigated with saline water.Germination percentage, height, leaf area, tiller number, percentage of senescing leaves, chlorophyll content, shoot dry weight and grain yield varied significantly between genotypes.This implies that intraspecific genetic...
This study addresses the development of unpollinated and pollinated flowers date palm (Phoenix dactylifera L.). cv. Deglet Noor in three successive seasons (2015–2017), focusing on physico-chemical characterization functional properties fruits at Kimri stage. Results showed for first time that dropped stage have a clear beneficial action human health compared even with Tamar stage, given its higher total polyphenols antioxidant activity, 3 34 times superior to respectively.
Availability of efficient male genotypes is critical for successful artificial pollination and regular bearing female date palms. The effect flowering stage storage conditions on pollen quality six palm encoded 'ABD1', 'P4', 'P3', 'P8', 'P7' 'P13'were evaluated. Pollen collected from spathes developed at the middle exhibited best viability (90%) germinability (85%) compared to other stages. was greater than 90%, except 'P8' that 80%, while, greatly varied among genotypes. decreased during 4...
Tunisian oases reveal an important genetic heritage of date palm cultivars, with various qualities use. Since the beginning century, this has evolved to a selective orientation based on monoculture "Deglet Nour," risks causing loss many cultivars. The male is part and so far remains marginalized. Although they are for production cycle, it in context that lies our work study diversity collection pollinators from southern Tunisia. morphological 20 using 45 IPGRI (International Plant Genetic...
The genetic variation and relationships among 12 local barleys the varieties Martin Manel were evaluated using random amplified polymorphic DNA (RAPD) simple sequence repeat (SSR). A high level of polymorphism was found with both RAPD SSR markers the mean information content (PIC) values 0.477 0.533 for markers, respectively. In analyses, 69 out 93 bands (74%) polymorphic. number alleles ranged from 4 to 10 per primer, an average 6.2 primer. RAPD-based dissimilarity...
In Tunisian oases, pollination remains a traditional process and the male’ spikelets are manually inserted into female inflorescences. The drawback of this ancestral practice forced us to look for new alternative technique improving date palm productivity. present investigation aimed compare agronomic biochemical characteristics ‘Deglet Nour’ variety following three techniques: handmade technique, dusting (spraying pollen grains by powder) water suspension technique. results affirmed that...
