This research was intended to define and interpret cell wall attributes and other chemical composition of eight different varieties of tomato plants by utilizing fiber optic Fourier-transform near-infrared spectroscopy (FT-NIR) to acquire in situ chemical signatures of leaf, flower, fruit, and stem of tomato plant and cell wall at different developmental stages. Chemical spectral signatures of the tomato’s leaf, flower, fruit, and stem were only acquired during its session and in live mode such as green, yellow, and red in cell wall color. The spectral signature analysis of each tomato plant was performed to see substantial differences in chemical compositions using chemometric data modeling of FT-NIR spectra. In addition, principal component analysis (PCA) was performed to discriminate leaf, flower, fruit, and stem from the same variety. PCA was also performed to differentiate eight different varieties of tomato plants. The study showed how in situ FT-NIR could distinguish eight types of tomato leaf, flower, fruit, and stem chemical composition at different developmental stages related to cell wall and other attributes. This study has also demonstrated how in situ FT-NIR can discriminate between rusty vs. healthy leaf and intact fruit vs. off-the-plant fruit. The main objective of this study is to present the chemical signature differences in the live and developing tomato plants to improve crucial factors of tomatoes that would benefit plant breeding, tomato cell wall study, and ultimately human health.

使用光纤傅里叶变换近红外光谱对番茄植株和细胞壁进行原位成分分析

本研究旨在通过利用光纤傅立叶变换近红外光谱 (FT-NIR) 获取叶、花、果实的原位化学特征来定义和解释八种不同番茄植物的细胞壁属性和其他化学成分，以及处于不同发育阶段的番茄植物和细胞壁的茎。番茄叶、花、果实和茎的化学光谱特征仅在其生长期间和活体模式下获得，例如细胞壁颜色的绿色、黄色和红色。使用 FT-NIR 光谱的化学计量学数据建模，对每株番茄植物进行光谱特征分析，以查看化学成分的显着差异。此外，还进行了主成分分析 (PCA) 以区分来自同一品种的叶、花、果实和茎。还进行了 PCA 以区分八种不同的番茄植物品种。该研究展示了原位 FT-NIR 如何区分八种类型的番茄叶、花、果实和茎在与细胞壁和其他属性相关的不同发育阶段的化学成分。这项研究还展示了原位 FT-NIR 如何区分生锈的叶子与健康的叶子以及完整的果实与离植的果实。本研究的主要目的是展示活的和发育中的番茄植株的化学特征差异，以改善番茄的关键因素，从而有利于植物育种、番茄细胞壁研究，并最终促进人类健康。以及与细胞壁和其他属性相关的不同发育阶段的茎化学成分。这项研究还展示了原位 FT-NIR 如何区分生锈的叶子与健康的叶子以及完整的果实与离植的果实。本研究的主要目的是展示活的和发育中的番茄植株的化学特征差异，以改善番茄的关键因素，从而有利于植物育种、番茄细胞壁研究，并最终促进人类健康。以及与细胞壁和其他属性相关的不同发育阶段的茎化学成分。这项研究还展示了原位 FT-NIR 如何区分生锈的叶子与健康的叶子以及完整的果实与离植的果实。本研究的主要目的是展示活的和发育中的番茄植株的化学特征差异，以改善番茄的关键因素，从而有利于植物育种、番茄细胞壁研究，并最终促进人类健康。
