Physiological quality seeds Clitoria fairchildiana R. A. howard during storage

Abstract

ABSTRACT:The species Clitoria fairchildiana R. A. Howard, belonging to the family Fabaceae is a fastgrowing ornamental tree, with potential for use in reforestation for heterogeneous vegetation reconstruction and recovery of degraded areas. Storage is aid in quality programs, which allows the preservation of the quality of seeds, however, the water content of the same is a crucial factor in its preservation, because it is high may cause deterioration and death of seeds stored. In this way the objective to evaluate the germination and vigor of seeds of C. fairchildiana stored with different levels of water. That's way was an experiment in completely randomized design in a factorial 5 x 7 (water levels and periods of storage). Before storage for 20, 40, 60, 80, 100 and 120 days, the seeds were subjected to drying in an oven at 40 °C for 0, 6, 12, 18 and 12:0 am, to obtain the following water levels: TA 1 = 19.05, TA 2 = 13.60, TA 3 = 11.99%, TA 4 = 10.51% and TA 5 = 8.70%, respectively. After each interval of storing seeds were subjected to the following evaluations: determination of the moisture content, germination and vigor tests (emergency, first count of germination and emergence and germination speed index and emergence, seedling dry mass and length). The reduction of water content of seed C. fairchildiana to 10.5 and 8.7% (TA 4 TA 5 and, respectively) resulted in greater preservation during storage, giving Orthodox behavior for stand drying until it reaches the water content of around 8%.

Drying and physiological quality of palheteira seeds (Clitoria fairchildiana R.A. Howard)

“…Alves et al (2015) andPelissari et al (2018) studying seed desiccation classified palheteira seeds as orthodox, diverging from the present study that classified palheteira seeds as intermediate in storage. Alves et al (2015) dried palheteira seeds around 8% and 78% of germination, but according to Hong and Ellis (1996), this water content is a characteristic of intermediate species, and orthodox species have a desiccation of at least 2% to 6% moisture content depending on the species.…”
