Reproductive Biology Data of Avena ludoviciana in relation Elevated Temperature

Avena sterilis ssp. ludoviciana data on reproductive biology of four A. ludoviciana biotypes in relation to elevated temperature when applied at different times during their seed development. Plants of all four A. ludoviciana biotypes were grown in an ambient temperature glasshouse (23/14 C day/night). At panicle initiation, a portion of the plants were transferred to an elevated temperature glasshouse (29/23 C day/night) and remained there until maturity. This process of plant movement was repeated on three further occasions with separate batches of plants, each 10 days apart. The remaining plants were kept under ambient conditions for their whole lifespan. Plants exposed to elevated temperature from panicle initiation to maturity, matured 18 days earlier than plants kept under ambient conditions, had 30% fewer filled seeds, 37% lower seed mass, and 40% less seed dormancy.

本数据集涵盖假野燕麦（Avena sterilis ssp. ludoviciana）4个生物型在种子发育不同阶段施加高温处理时的生殖生物学相关研究数据。所有4个路德维吉假野燕麦生物型的植株均种植于常温温室（昼/夜温度23℃/14℃）中。在穗始期，将部分植株转移至高温温室（昼/夜温度29℃/23℃）并培养至成熟。该植株转移操作另外在三批独立植株上重复开展，每批间隔10天。剩余植株则全程在常温环境下培养。从穗始期至成熟全程暴露于高温环境的植株，较全程常温培养的植株提前18天成熟，其饱满种子数量减少30%，种子质量降低37%，种子休眠性下降40%。
