Quantification, using an accurate analytical approach, of capsinoids and capsaicinoids was performed on three chili pepper (Capsicum spp.) genotypes: “Chiltepı́n”, “Tampiqueño 74”, and “Bhut Jolokia” at various stages of fruit development. The accumulation of capsinoids, in all these peppers started between 10 to 20 days post-anthesis (dpa), increased and reached the highest capsinoid amount at 40 dpa, and then decreased until 60 dpa. Conversely, capsaicinoids could already be determined at 10 dpa in “Bhut Jolokia” and their accumulation pattern was different from that of the capsinoids in this genotype. The capsiate/dihydrocapsiate ratio presented a higher variation between genotypes and developmental stages than the capsaicin/dihydrocapsaicin ratio. Capsinoid ratios (4–24%) and Pun1/pAMT genotyping were determined. These results provide information on the progress of the accumulation of capsinoids in the aforementioned pungent and superhot cultivars and could support future breeding studies toward the understanding of the factors affecting their accumulation.

果实发育三个辣椒基因型中辣椒素和辣椒素酯类物质积累模式的评估(辣椒属)携带Pun1中pAMT等位基因相关的辛辣

使用准确的分析方法,在水果发育的各个阶段,对三种辣椒(辣椒),“辣椒”,“坦皮诺尼奥74”和“布托乔洛基亚”的基因型进行了辣椒素和辣椒素类化合物的定量分析。在所有这些辣椒中,辣椒素的积累在花后10到20天之间开始(dpa),在40 dpa时增加并达到最高的辣椒素含量,然后下降到60 dpa。相反,“ Bhut Jolokia”中已经确定了10 dpa的辣椒素类化合物,其积累模式不同于该基因型中的辣椒素类化合物。与辣椒素/二氢辣椒素的比率相比,辣椒素/二氢辣椒素的比率在基因型和发育阶段之间表现出更高的变化。辣椒素比率(4–24%)和双关语1确定了/ pAMT的基因型。这些结果提供了关于在上述辛辣和超热品种中辣椒素积累的进展的信息,并且可以支持未来的育种研究,以了解影响它们积累的因素。
