Their early development rate and hatching ratio were observed on the 10th, 31st, 65thand 227th days after the accomplishment of the flight. Three main results were obtained asfollows: (i) The treatment accelerated the development of the eggs not flown; (ii) it also en-hanced the resistance of the flown eggs against unfavorable spaceflight effects (retarding ear-ly development and lowering the hatching ratio), and promoted the recovering ability of theflown eggs from the affected state; and (iii) the latent beneficial effect produced by treatmentwas found to be very durable, still appearing in the development of the treated eggs on the318th day after treatment (the 227th day after the flight).展开更多
