  Okra is warm season crop native to Africa. Presently it is widely grown in the northeastern parts of Brazilia, both northen, and western parts of Africa, southeast Asia, and in the eastern parts of the Mediterraneum. In Hungary it is a rarity. It’s adaptation to Hungary began about 40 years ago.The optimal sowing time under Hungarian climatic conditions is middle of May. The harvests is started – depending on the weather – first, by the middle of July, and picking continues until the first of September.
  According to our results, seed soaking, sowing under a perforated foil sheet-covered trench (2 weeks earlier the normal sowing time), and 55-65 g thousand weight seeds are favourable.
  The harvest period under Hungarian circumstances is appr. one and half months.

  Various abiotic stresses including high salinity strongly affect seed germination. Three Hungarian wheat landraces Gamási, Fóti and Kartali have been tested for seed germination, seedling growth and chemicals parameters when seeds were soaked in gibberellic acid (GA3) at the concentrations of 0, 75 and 150 ppm and at four levels of salinity stress 0, 5, 10 and 15 dSm-1. A laboratory experiment took place at Research Institute of Nyíregyháza. Factorial Experiment based on Randomized Complete Block Design (RCBD) in four replications has been conducted. Seed soaking in GA3 before sowing significantly affected germination characteristics, seedling properties and the results of chemical analysis. The highest germination as well as K+ content of seeds were observed at seed soaking into 150 ppm GA3. However, Na+ and proline contents in seedling were decreased. The behavior of the tested Hungarian wheat varieties was genotype-dependent. Increasing salinity stress up to 15 dSm-1 significantly affected germination characteristics, seedlings parameters and chemical analysis. Fóti variety turned out to be the best at 150 ppm GA3 compared to the other two varieties. Moreover, it had the lowest Na+ and proline contents and highest K+ content.
