在原民主德国,培育耐旱性强的黑麦品种是一重要育种目标.研究发现黑麦抽穗—开花期对干旱胁迫最为敏感;生物学产量高、开花前茎秆中同化的贮藏物质多、育性好的品种,干旱胁迫后籽粒产量仍较高.测定脯氨酸含量有助于评价耐旱性.Al(铝)测验可用于单株选择.在塑料薄膜建造的温室内,可以非常可靠地检测耐旱性;采用水培法以无性繁殖方式可以培育耐旱性强的育种材料.
In the former Democratic Germany, breeding of drought-tolerant rye cultivars is an important breeding goal.It is found that the heading and flowering stages of rye are the most sensitive to drought stress, the biological yield is high, and the amount of stored materials assimilated in stems before flowering is high Good quality varieties, the grain yield is still high after drought stress Determination of proline content helps to evaluate the drought resistance Al (aluminum) test can be used for single plant selection in the plastic film greenhouse construction, can be very reliable Detecting drought tolerance; using hydroponics to reproduce asexual breeding breeding materials with strong drought tolerance.
