‘valencia’ Sweet Orange Tree Flowering Evaluation under Field Conditions
Since citrus flowering is a key process in citriculture and its evaluation is often difficult due to the canopy structure and field sampling, the aim of this research was to give some directions regarding the evaluation of flowering in field-grown sweet orange plants. This study was conducted in a citrus orchard of sweet orange plants cv. ‘Valencia’ [Citrus sinensis (L.) Osbeck] grafted on ‘Cle...
متن کاملResveratrol content in strawberry fruit is affected by preharvest conditions.
This study investigated the occurrence of resveratrol in Fragaria x ananassa Duchesne and the effect of preharvest conditions on resveratrol content. Both cis- and trans-resveratrol were detected in strawberry achenes (seeds) and pulp (receptacle tissue). Resveratrol was found to be higher in achenes than in fruit pulp. The levels of resveratrol were affected by genotype variations, fruit matur...
متن کاملGC-MS analysis of headspace and liquid extracts for metabolomic differentiation of citrus Huanglongbing and zinc deficiency in leaves of 'Valencia' sweet orange from commercial groves.
INTRODUCTION Citrus Huanglongbing (HLB) is considered the most destructive citrus disease worldwide. Symptoms-based detection of HLB is difficult due to similarities with zinc deficiency. OBJECTIVE To find metabolic differences between leaves from HLB-infected, zinc-deficient, and healthy 'Valencia' orange trees by using GC-MS based metabolomics. METHODOLOGY Analysis based on GC-MS methods ...
متن کاملCsHPt1, a putative histidine-containing phosphotransmitter protein induced during early somatic embryogenesis in Valencia sweet orange
A cDNA named CsHPt1 (for Citrus sinensis histidine phosphotransmitter protein 1) containing a conserved domain characteristic of a twocomponent phosphorelay intermediate associated with signal transduction mechanisms, was isolated from globular embryos of C. sinensis sweet orange cv. ‘Valencia’ by differential display RT-PCR. The corresponding full-length cDNA, subsequently obtained by RACE-PCR...
متن کاملAbility of ‘Valencia’ Sweet Orange to Cold-acclimate on Cold-sensitive Citron Rootstock
Greenhouse-grown l-year-old sweet orange trees [Citrus sinensis (L.) Osbeck cv. Valencia] on cold-hardy trifoliate orange [Poncirus trifoliata (L.) Raf.] and cold-sensitive citron (C. medica L.) rootstocks were exposed to cold-acclimation conditions and freeze-tested at -6.7C for 4 hours in a temperature-programed walk-in freezer room. Nonhardened trees generally did not survive the freeze, whe...
