葡萄硬枝插条的花穗通常在发芽后就枯萎而死。最初由Mullins设计用之于试验植株而使插条少量结实的方法,现已加以改进。这种方法是:在一间冷屋(4℃)里,插条置于加热箱中(插条基部为26℃)生根,芽则保持休眠。四周后,生了根的插条移入温室或栽培室昼27℃、夜22℃,60瓦米~(-2)的光,16小时光照。)发芽时,一看到花穗基部的和邻近的叶片就掐去,然后掐掉顶尖。这些处理可促进花穗生长。在主梢上许多去
The spikes of grapes and hardwood cuttings usually die after germination. Mullins has been originally designed to test the plant and make a small amount of strong cuttings, has now been improved. This method is: in a cold room (4 ℃), cuttings placed in the heating box (cuttings at the base of 26 ℃) rooting, buds remain dormant. Four weeks later, the rooted cuttings were moved into the greenhouse or daylight at 27 ° C, night at 22 ° C and 60 W (-2) light for 16 hours. ) When germinated, the spikes are pinched at the base and adjacent leaves of the spikes, then pinched off. These treatments can promote flower spike growth. On the main shoot many go
