Abstract
The hot pepper Dedo-De-Moça (girl-finger) is one of the most consumed peppers in Brazil, mainly in the south and southeast regions.
This hot pepper gives a mild pungency and is generally used as dried flakes or in sauce manufacturing.
Farmers usually use their own seeds and establish the crops by transplanting.
Thus, the seed quality, and hence stand establishment, are not always satisfactory due to compromised genetic purity, low seedling vigor and contamination of microorganisms.
This paper describes seed technology to improve the physiological quality of hot pepper seeds in Brazil. Mari hot-pepper fruits were harvested at different stages of maturation and seed were extracted from fruits by different methods.
Seeds were also osmoconditioned and incubated for germination at different temperatures.
Seeds of Mari red hot pepper fruits had the best germination and vigor when harvested at approximately 60-70 days after anthesis.
Seeds extracted mechanically provided better yield and better quality compared with those extracted manually.
Osmoconditioning improved germination at high temperature (35°C). The results obtained in the different studies will be discussed.
