Abstract

Once “bode” pepper plants (Capsicum) have continuous development and fructification, it is not possible to determine a specific season for seed physiologic maturation and harvest. This research aimed to evaluate physiological quality of “bode” pepper (Capsicum chinense 'Adjuma’) during fruit development and enzymes expression on seed germination. Manually extracted seeds were submitted to physiological tests being evaluated germination at first count (FC), final (G), and germination speed index (GSI), additionally, enzymatic analyses were carried. The lowest values for the physiological tests were observed for initial development stages. The greatest for FC, G and IVG were observed for seeds from fruits 70 days after anthesis (DAA). Superoxide dismutase enzyme has the highest values on seeds harvested at 49 DAA while malate dehydrogenase has more expression at 70 DAA. Catalase, alcohol dehydrogenase, and esterase have the higher expression at 63 DAA. The maturation stage influences bode pepper seed physiological quality, being seeds harvested at 70 DAA those with the better results on the evaluated parameters, thus, considered physiologically mature and the indicated time for harvest.

辣椒'Adjuma'种子发育过程中的生理品质

一旦“博德”辣椒植物（辣椒）持续发育和结果实，就不可能确定种子生理成熟和收获的特定季节。本研究旨在评价“博德”辣椒（Capsicum chinense‘Adjuma’）在果实发育过程中的生理品质以及种子发芽过程中酶的表达。将人工提取的种子进行生理测试，评估首次计数（FC）、最终计数（G）和发芽速度指数（GSI）的发芽率，此外，还进行了酶分析。生理测试的最低值是在初始发育阶段观察到的。花后70天果实中FC、G和IVG含量最高。超氧化物歧化酶在49 DAA收获的种子上具有最高的值，而苹果酸脱氢酶在70 DAA时具有更多的表达。过氧化氢酶、醇脱氢酶和酯酶在63DAA处有较高的表达。成熟阶段影响bode辣椒种子的生理质量，在70 DAA下收获的种子在评估的参数上具有更好的结果，因此被认为是生理成熟和指示的收获时间。
