Abstract

Grafted and ungrafted ‘Primo Red’ tomato (Solanum lycopersicum) transplants were planted at 16-, 20-, and 24-inch spacing in a commercial high tunnel in central New York, USA, to compare yields. ‘Primo Red’ scions were grafted onto ‘Maxifort’ rootstocks and left to heal in a commercial greenhouse facility. Tomatoes were harvested as they ripened, and the weight and number of fruit per plot was recorded and then calculated out to a per-plant basis. Wider plant spacings resulted in higher yields for both grafted and ungrafted plants. However, economic returns remained highest in the highest density (16 inches in-row) spacing with grafted plants. This indicates that growers may not need to adjust density despite additional foliage from grafted plants. Foliar incidence of Botrytis gray mold (Botrytis cinerea) was not significantly different under spacing or grafting treatments. Grafting resulted in higher yields across all plant spacings compared with ungrafted plants. Commercial growers can use this information to make choices on grafting and spacing in high tunnel tomato.

‘Primo Red’高隧道番茄嫁接的最优间距
移植和未移植的‘Primo Red’番茄(Solanum lycopersicum)以16、20和24英寸的间距种植在美国纽约市中心的一个商业高隧道中,以比较产量Primo Red的接穗被嫁接到Maxifort的砧木上,并在商业温室设施中愈合。番茄在成熟时收获,记录每个地块的果实重量和数量,然后按单株计算。植株间距越大,嫁接植株和未嫁接植株的产量都越高。然而,在嫁接植物的最高密度(行间距16英寸)处,经济回报仍然最高。这表明,尽管嫁接植物有额外的叶子,种植者可能不需要调整密度。灰霉菌(Botrytis cinerea)的叶片发生率在间隔处理和嫁接处理下没有显著差异。与未嫁接的植物相比,嫁接导致所有植物间距的产量更高。商业种植者可以利用这些信息来选择高通道番茄的嫁接和间距。
