激光技术在果树育种的应用

在激光果树育种中,激光的生物效应不仅取决于辐照时的激光参数,也取决于被辐照组织的部位、辐照季节等。本文对如何预选激光参数,并对激光诱变生物效应的机制均进行了探讨。紫外和可见激光的诱变机制主要是光化学反应;红外激光的诱变机制,在强激励方式下主要是多光子吸收,在弱激励时则热效应和非热的相干共振效应同时存在。

APPLTCATION OF LASER TECHNOLOGY IN FRUIT TREE BREEDING

In Laser genetic breeding field, the biological effects of lasers depend not only on irradiate parameters but also on the irradiate position on a living organism and on a season and so on. The mechanism of induced mutation of UV and visible laser can be briefly described as a photochi-niacal reaction. When strong doses infrared laser is absorbed mainly by methed of multipliphoton. When weak doses thermal effects and coherence reosonance (non-thermal) effect exist simultaneously.
