The effect of different water depths on the growth of wild rice

摘要: The effect of different water depths on wild rice plants (Zizania aquatica L.) was assessed in terms morphological and dry weight changes which occurred during a complete life cycle. Specifically, plant heights, number area leaves, weights leaf, stem, root, flower were determined for grown under controlled environmental conditions those field at Long Point, Lake Erie.Three distinct phases height increase, associated characterized the cycle rice. While duration one three unaffected by depth, time spent phase two increased with depth resulted flowering later than shallower depths. Sufficient is required to cover submersed leaves support floating while aerial stage survived no free above rooting media. Yield parts decreased less 8 cm greate...
