摘要

种子成熟过程中的不断变化影响其最终品质和采后果实静息,从而提高种子的生理品质。因此,本研究的目的是评估从不同年龄和收获后静息期的茄子果实中提取的种子的生理和酶活性。在开花后40、50、60和70天收获不同颜色的水果,休息0天(新鲜收获的水果)、10天和20天。试验设计为完全随机,4个重复,每小区6个果实提取种子。在小于60 DAA的时间内,茄子果实的静息期提高了1000粒种子的质量、发芽率、活力和蛋白质含量。发芽率高、活力强的种子,歧化酶(SOD)、过氧化氢酶(CAT)和过氧化物酶(POX)活性较低。结果表明,茄子制种的理想收获时刻是果实达到黄褐色,对应于60 DAA左右;然而,如果茄子果实收获较早(40或50 DAA),则需要休息约10至20天才能达到较高的生理品质(发芽和活力)。

Physiological quality and antioxidant enzymes activity in eggplant seeds with different ages and resting periods after harvest
ABSTRACT Constant changes during the seed maturation process affect its final quality and the post-harvest fruit resting, which can improve seed physiological quality. Therefore, the objective of this study was to evaluate the physiological and enzymatic activities of eggplant seeds extracted from fruits harvested at different ages and resting periods after harvest. Fruits were harvested presenting different colors at 40, 50, 60, and 70 days after anthesis (DAA) and rested for 0 (freshly harvested fruits), 10, and 20 days. The experimental design was set as completely randomized, with four replications and evaluated seeds extracted from six fruits per plot. The resting periods in eggplant fruits harvested at less than 60 DAA improved the mass of 1000 seeds, germination, vigor, and protein content. Seeds with higher germination and vigor presented lower dismutase (SOD), catalase (CAT), and peroxidase (POX) enzymatic activity. The results indicated that the ideal moment of eggplant harvest for seed production is when the fruit reaches the yellowish-brown color corresponding to about 60 DAA; however, if the eggplant fruit is harvested earlier (40 or 50 DAA), it has to rest for about 10 to 20 days to achieve high physiological quality (germination and vigor).
