Harvest date modifies seed quality and oil composition of Jatropha curcas growth under subtropical conditions in Argentina
One of the most currently promoted new crops for biodiesel productions the perennial species Jatrophacurcas L. [Euphorbiaceae] due to its promising high seed yields with high oil concentrations [33.39 per cent] and oil quality that reaching the international biodiesel standards. Although there have...

| 520 | |a One of the most currently promoted new crops for biodiesel productions the perennial species Jatrophacurcas L. [Euphorbiaceae] due to its promising high seed yields with high oil concentrations [33.39 per cent] and oil quality that reaching the international biodiesel standards. Although there have been differentevaluations of genotypes growing under the same environmental conditions, revealing great variabilityfor seed and oil quality, no reports are available about the effect environmental conditions during grainfilling over such traits. The objectives of this work were to determine [i] the effect of harvest dates on seed quality and oilconcentration, [ii] if such changes can be explained by the average temperature during grain filling and [iii], how harvest dates could affect biodiesel quality. An experiment was carried out during 29 monthsin experimental plots located in Formosa, Argentina. A systematic fruit harvest was conducted during 15different dates on 10 plants with similar height [.1.80 m]. Environmental conditions during the exper-iment were appropriate to create a broad individual seed weight range [326.752 mg] and significantdifferences were found among harvest dates. Seed oil concentrations were significantly different amongharvest dates with a maximum value of 38.7 more/less 0.6 per cent on 08 August 2011 and a minimum of 19.6 more/less 1.8 per cent on17 March 2010. Oil concentration increased linearly as seed weight increased up to a value of 605 mg,after which higher seed weight was not associated with greater seed oil concentration. Oil concentrationwas largely [r2= 0.85] explained by the kernel percentage through a linear regression [y = .25.9 + 0.967x]. Variations in seed weight and oil concentration were not associated with changes in average temper-ature during grain filling, suggesting that fluctuations in the source-sink relation through the growingseason could explain the variations found among harvest dates. Temperature during seed filling periodstrongly affected oil composition and higher temperatures were associated with higher oleic acid andlower linoleic acid concentrations, although this effect generated only small effects on the biodiesel qual-ity. Environmental conditions during grain filling modified seed quality and oil composition, while itsconcentration was not affected. This work reveals the existence of harvest dates effects on seed qual-ity and oil concentration, although unrelated with the environmental conditions explored during grainfilling period. | ||
