- Carrot tissue culture and plant regeneration factors including explants , medium and culture condition are combined together to study the most efficient protocol of carrot tissue culture and plant regeneration thereof . the most suitable explant is fresh hypocotyls segment and precultured hypocotyls derived from 7 - 10 day old aseptic plantlets generating in dark or in dim light , the best recipe for cullus induction and subculture is b5c ( 85 with 0 . 5mg / l 6ba and 0 . 5mg / l 2 , 4 - d ) , the ideal recipe for plant regeneration is 65 or ms free of hormone . a phytotron with a 16 / 8 h day / night cycle , at 25 is feasible for plant regeneration , and occasional exposure to sun light dramatically stimulates plant growth
建立了高效的胡萝卜组织培养及再生体系以适于生产饮料的胡萝卜“新黑田五寸人参”为材料，研究不同外植体、不同培养基，不同培养条件对胡萝卜愈伤诱导及再生的影响，建立一套高效的胡萝卜组织培养再生体系：最适于诱导愈伤的外植体是弱光或黑暗下发芽7 - 10d无菌苗下胚轴，最适合的愈伤诱导培养基和继代培养是b _ 5c ( b _ 5 + 0 . 5mg l6ba + 0 . 5mg l2 ， 4 - d ) ，最适于植株再生的培养基为不添加任何激素的b _ 5或ms ，组织培养条件为25 、光照周期为16hr 8hr 。 - A detailed literature review of physiological effects of light on laying hens was undertaken , with reference on the effects of light intensity , photoperiod and light color on the ontogenetic , survive , feeding , growth , reproduce abilities , in order to provide some information for research work and application in this field in the future
摘要本文综述了光照对蛋鸡生理学特征影响的研究进展，主要涉及光照周期、光照强度和光色对蛋鸡个体生长发育、存活、摄食、生长、繁殖等方面的研究进展，以期为我国进行该领域的研究和指导养殖实践提供一定的参考。
