“…The availability of the same nutrients for both plants might explain the similarity in their residue's chemical elements. The correlations between nutrients in this study agreed with the results of Ogidi et al [40] when they were working on soil-plant nutrients.…”

“…In fact, for some elements, both negative and positive correlations between the contents of the element in soil and olive oil have been reported in the literature. It has been stated that a negative correlation indicates that the form of the element in question is not available to plants because the chemical conditions in soil can affect the pH and the solubilities of elements in the soil (Tyler and Olsson 2001;Ogidi et al 2018). Table 3 shows the median bioavailable concentrations (and the associated standard deviations) of the elements of interest in all of the soil samples.…”

“…These findings indicate that elements which displayed a negative correlation when the soil bioavailable content was considered were not available to plants, even when the CaCl 2 -soluble form was used as a model for the bioavailable concentration. This could be because CaCl 2 -soluble forms are not suitable for use as bioavailable models or because the soil chemical conditions affect the soil pH and the solubilities of elements, especially given that CaCl 2 is unbuffered so it does not modify the original pH of the soil (Tyler and Olsson 2001;Ogidi et al 2018).…”

“…A number of authors have observed various interactions where element uptake by plants is influenced by interference and competition between elements due to changes in soil pH (Ogidi et al 2018). In fact, all of the significant (p < 0.05) correlations between element concentrations in olive oil and soil pH were positive, implying that when the pH increases, the concentrations of these elements in olive oil increase as well.…”

Olive oil traceability based on the intrinsic chemical composition of the oil is becoming increasingly important due to the prevalence of fraudulent geographical labelling of olive oils. For a traceability tool to be valid, it should be based on olive oil properties that are clearly related to provenance factors. However, multielement analysis of the oil has been used as a traceability tool without any proof of a direct link between the multielemental composition and the geographical origin of the oil. In order to verify this link, Tunisian olive terroir components from the 11 major olive-producing regions were sampled to evaluate the influences of these components (especially soil and climate) on the geochemical composition of Tunisian olive oil. Overall, geochemical processes relating to strontium and rare-earth element (REE) enrichment were found to control the multelemental compositions of Tunisian soils. Even though olive oils from the 11 Tunisian olive-growing regions considered did not strongly reflect the geochemical signatures of the corresponding Tunisian soils, the concentrations of four elements in the oils, namely Fe, Ti, Ni and Ba, showed significant positive Spearman correlations with their concentrations in the bioavailable extracts from those soils. Moreover, there were numerous significant correlations of elements in the olive oil with soil chemical and climate parameters. Our results clearly confirm that the complex interactions of the olives with the climate and soil chemistry during cultivation significantly affect the multielemental composition of the resulting olive oil. This finding implies that the elemental profile of the olive oil is an effective and valid marker of the geographical origin of the oil, as it is significantly linked to oil provenance factors. It also explains the discrepancies between the geochemical signature of an oil and that of the soil in which the olives were grown, as climate parameters affect the transfer of that signature from soil to olives. This work therefore provides the basis for a scientifically based approach to olive oil traceability. The results of this work can be utilized by agricultural authorities to realise the multielement-based traceability of olive oils from various Tunisian regions. Graphic abstract

“…Hasil pengamatan menunjukkan sebagian besar aksesi tidak menghasil-kan cabang autotrof muda sehingga tidak memungkinkan digunakan sebagai bahan perbanyakan okulasi. Ogidi et al (2018) melaporkan bahwa semakin tua tanaman karet (entres) semakin menurun jumlah dan kualitas mata tunas yang dihasilkan. Tanaman yang digunakan sebagai sumber entres memiliki batas usia maksimal hingga 18 tahun (Indarty 2000), namun idealnya umur tanaman entres berkisar 5-10 tahun berdasarkan pertimbangan juvenilitas tanaman dan perkembangan klon-klon unggul terbaru (Seneviratne 2000(Seneviratne , 2009Siagian 2012).…”

<p>Ribuan aksesi plasma nutfah karet IRRDB 1981 (PN’81) merupakan material genetik tanaman karet yang diperoleh dari habitat aslinya di hutan hujan tropis Brasil yang dikoleksi oleh International Rubber Research and Development Board pada tahun 1981. Material genetik yang ditanam di Kebun Percobaan Balai Penelitian Sungei Putih ini dimanfaatkan dalam program perakitan klon unggul tanaman karet. Pelestarian PN’81 dalam bentuk kebun koleksi ex situ sudah tidak lagi relevan karena cara ini membutuhkan areal yang luas (58,5 ha), biaya pemeliharaan besar, dan rentan terhadap gangguan faktor alam maupun manusia. Penelitian ini bertujuan untuk melestarikan koleksi PN’81 dalam bentuk kebun entres sehingga koleksi tersebut tidak rusak dan hilang. Penelitian dilakukan menggunakan metode deskriptif dengan seluruh anggota populasi sebagai sampel. Pengamatan dilakukan secara langsung terhadap jumlah tegakan yang tersisa, jumlah mata entres, keberhasilan okulasi, dan pertumbuhan mata okulasi. Hasil reinventarisasi menunjukkan bahwa terjadi penurunan jumlah aksesi yang sangat tinggi, yaitu sebesar 8.322 aksesi selama periode 1990–2018. Penurunan disebabkan oleh beberapa faktor, di antaranya adalah usia tanaman, gangguan hewan dan manusia, serangan penyakit, kebakaran, dan serangan angin. Sebagian besar aksesi PN’81 menghasilkan sedikit cabang autotrof muda dan persentase keberhasilan okulasi rendah. Hasil pengamatan pertumbuhan tunas okulasi bulan kesembilan menunjukkan nilai koefisien keragaman yang cukup besar dan sebanyak 33% tanaman mengalami gangguan pertumbuhan di lapangan (kebun entres). Upaya pelestarian plasma nutfah PN’ 81 dalam bentuk kebun entres hanya dapat menyelamatkan 12,5% aksesi dari total koleksi plasma nutfah PN’81.</p>
