根据文献资料,冬小麦的越冬性主要决定子分蘖节的抗寒力。有鑑于此,康薩斯州农业试验站曾进行试验,研究多次冷冻对冬小麦巴乌尼品种分蘖节组织的影响。小麦栽植于直径为10厘米的盆缽中(每缽10株)。带株盆缽在12月中旬之前假植于露地,而后分别在人工条件下于零下15.5度的温度中冷冻一昼夜1到5次。供试各组植株均为50株。冷冻后自每组取10
According to the literature, winter wheat winter mainly determine the sub-tillering section of the cold hardiness. In view of this, the state of Kentucky Agricultural Experimental Station has conducted experiments to study the effect of multiple freezing on the tillering node of Bomboni variety of winter wheat. The wheat is planted in pots with a diameter of 10 cm (10 per pot). The stalk pots were planted in the open field before mid-December and were then frozen under artificial conditions for 1 to 5 times a day at temperatures of minus 15.5 degrees Celsius. The test group of plants are 50. After freezing 10 from each group
