چکیده
The Ivorian coast is the main coconut production area where agriculture mainly rainfed. However, in this area, climate variability poses a great threat to growth and sustainable development of agriculture. This study aimed at highlighting impacts on most popular Dwarf x Tall palm hybrids world. It based evaluation from statistical tests (ANOVA, STUDENT's T-test 5%) results standardized precipitation evapotranspiration indices (SPEI) during period 2009 2018 area. obtained revealed that NJM×GOA+ hybrid was significantly differentiated by its good potential bunches (10 bunches), fruits (151 nuts) copra (3.69 t). maximum fruit per year observed × (101 nuts). highest mass productions tree hectare were recorded hybrids. ten 2012, 2015 lowest 2014 2017. Productions gradually increase or remain stable for consecutive wet years (2009 2011) prior harvest. onset drought one (2012, 2013, 2015, 2016) pronounced two dry (2012 2013 harvest decrease level production. These cumulative effects are NRC×GRL+, NRM×GTN, NJM×GD001, NJM×GD002, NJM×GD003 NJM×GOA+, GVT×GTN, GSL×GTN, NRM×GVT, NVS×GVT developing abilities express themselves better under variability. They could be taken into account crop improvement program proposed growers improve yield trees rainfed conditions.

Physicochemical and Phytochemical Analyses of Copra and Oil of Cocos nucifera L. (West Coast Tall Variety)
Coconut copra from West coast tall variety, cultivated in Kerala, India, was subjected to aqueous and solvent extractions (using n-hexane). Additionally, oil was extracted from the copra in Soxhlet assembly using petroleum ether (b.p. 60-80°C). Physicochemical and phytochemical analyses were conducted for the extracts and the oil, with commercial coconut oil as the experimental control. The phy...
متن کاملPopulation structures of Brazilian tall coconut (Cocos nucifera L.) by microsatellite markers
Coconut palms of the Tall group were introduced to Brazil from the Cape Verde Islands in 1553. The present study sought to evaluate the genetic diversity among and within Brazilian Tall coconut populations. Samples were collected of 195 trees from 10 populations. Genetic diversity was accessed by investigating 13 simple sequence repeats (SSR) loci. This provided a total of 68 alleles, ranging f...
