不同品种高粱根系形态特征与产量形成的关系

摘要

选用目前辽宁省主要推广高粱品种辽杂10、辽杂13、辽杂18、锦杂93、锦杂100、沈杂5共6个为试材。开花期测定高粱不同品种根部形态指标,研究高粱根系形态特征与产量形成的关系,研究表明,地下部根系数量多,对高粱植株的生长发育和产量形成具有明显的促进作用。根冠比越大,越有利于高粱产量的形成。%Six main released varieties of Liaoza10,Liaoza13,Liaoza18,Jinza93,Jinza100,and Shenza5 in Liaoning were used as the test materials.The different sorghum varieties root morphological index were measured and the root morphological characters and yeild forma
