Among stone fruit, the peach (Prunus persica (L) Batsch) is one of the most widely grown species in Brazil, in both area cultivated and in production.
The aim of this study was to evaluate the physiological quality of heavy and light seeds of four cultivars of Prunus persica for two storage periods, from tests of electrical conductivity, germination, and an analysis of initial plantlets growth.
The Electrical Conductivity test (EC) was conducted in a Completely Randomised Design (CRD), in a 4 x 2 x 5 factorial scheme with five replications. The germination test was carried out in CRD, in a 4 x 2 factorial scheme with eight replications. The physiological quality of the seeds was determined at zero and twelve month's storage. For the growth analysis, the experimental design was in CRD, in a 4 x 2 factorial scheme with four replications.
Under the conditions of the present study, it was found that the tests of germination and electrical conductivity were complementary in evaluating physiological quality in seeds of Prunus persica rootstock, suggesting that independent of the weight of the seeds, in 'Capdeboscq', 'Aldrighi', 'Okinawa' and 'Okinawa Roxo', there is a loss of quality and viability when the seeds are stored for a period of 12 months.
Under the experimental conditions of the present study, it was concluded that storage for a period of 12 months in Recent patents is not rather recommendable for maintaining quality and viability in seeds of Prunus persica of the Capdeboscq, Aldrighi, Okinawa and Okinawa Roxo cultivars.
在核果类中，桃（Prunus persica (L) Batsch）是巴西种植面积和产量都最广泛的品种之一。
本研究的目的是通过电导率测试、发芽试验以及对幼苗初期生长的分析，评估四个桃品种重种子和轻种子在两个储存期的生理质量。
电导率测试（EC）采用完全随机设计（CRD），按4×2×5析因方案进行，重复五次。发芽试验采用CRD，按4×2析因方案进行，重复八次。在储存零个月和十二个月时测定种子的生理质量。对于生长分析，实验设计采用CRD，按4×2析因方案进行，重复四次。
在本研究条件下，发现发芽试验和电导率测试在评估桃砧木种子的生理质量方面具有互补性，这表明在‘卡德博斯克’、‘阿尔德里吉’、‘冲绳’和‘冲绳罗索’品种中，无论种子重量如何，储存12个月后种子质量和活力都会下降。
在本研究的实验条件下，得出结论，对于保持卡德博斯克、阿尔德里吉、冲绳和冲绳罗索品种桃种子的质量和活力而言，储存12个月不是很推荐。
