许多作者研究了草莓（Fragaria sp.）生产本研究在哥伦比亚以2500 masl进行。研究了红、蓝、黄、绿色、黑、银膜对草莓生长和果实的影响。在大多数因素上，红色覆盖物的结果与黑色对照相似或更好。叶面积、果实鲜重和果实长度以红色覆盖最高，银覆盖最低。银覆盖的pH值和干果重最低，可溶性固形物/可滴定酸的比值最低，而黑色覆盖的这一比值最高。红色覆盖物的积极影响可能是由于光敏色素对红光和远红光的吸收增加，这反过来又影响了与甜味和风味相关的酶。红色覆盖物的上级结果并不总是具有统计学意义，但本研究表明，对红色覆盖物与黑色覆盖物的效用进行进一步测试的兴趣。如果确实表明红色覆盖物提供更好的产量和质量，那么扩大和改进其生产并稳定其颜色将非常重要，因为在高海拔热带条件下，红色覆盖物往往会褪色。覆盖对草莓的形态发生有影响。生产在本研究中，在海拔2,500 m的试验中评估了红色、蓝色和果实质量的影响。在哥伦比亚中部。在大多数因素上，红色覆盖物的结果与黑色对照相似或更好。叶面积、鲜果重和果实长度以红色覆盖最高，银覆盖最低。银覆盖的pH值和干果重最低，可溶性固形物/可滴定酸的比值最低，而黑色覆盖的这一比值最高。红色覆盖物的积极影响可能是由于光敏色素对红光和远红光的吸收增加，这反过来又影响了与甜味和风味相关的酶。红色覆盖物的上级结果并不总是具有统计学意义，但本研究表明，使用红色覆盖物而不是黑色覆盖物进行进一步试验的潜在价值。如果确实表明红色覆盖物提供更好的产量和水果质量，那么扩大和改进其生产并稳定其颜色将非常重要，因为在高海拔热带条件下，红色覆盖物往往会褪色。
Various authors have studied the morphogenetic effects of the mulch used in strawberry ( Fragaria sp.) production. The present study was carried out at 2500 masl in Colombia. The effects of red, blue, yellow, green, black, and silver mulches were evaluated on strawberry growth and fruit. Red mulch gave results similar or better to the black control for most factors. Foliar area, fruit fresh weight, and fruit length were highest with red mulch and lowest for silver. Silver mulch gave lowest pH and dry fruit weight, and the lowest ratio of total soluble solids/titratable acidity, while black mulch gave the highest value in this ratio. Positive effects of red mulch are likely due to the increased absorption of red and far-red light by phytochrome, which in turn influences enzymes associated with sweetness and flavor. Superior results of red mulch were not always statistically significant, but the present study indicates the interest of conducting further tests on the utility of red mulch versus black mulch. If it were definitively shown that red mulch provides for better yield and quality, it would be important to expand and improve its manufacture and stabilize its color, which often fades under high altitude tropical conditions. Use of mulch has morphogenetic effects on strawberry ( Fragaria sp.) production. In the present study the effects of red, blue, and fruit quality were evaluated in a trial carried out at 2,500 m a.s.l. in central Colombia. Red mulch gave results similar or better to the black control for most factors. Foliar area, fresh fruit weight, and fruit length were highest with red mulch and lowest for silver. Silver mulch gave the lowest pH and dry fruit weight, and the lowest ratio of total soluble solids/titratable acidity, while black mulch gave the highest value in this ratio. Positive effects of red mulch are possibly due to the increased absorption of red and far-red light by phytochrome, which in turn influences enzymes associated with sweetness and flavor. The superior results of red mulch were not always statistically significant, but the present study indicates the potential value of further tests on the use of red mulch instead of black mulch. If it is definitively shown that red mulch provides for better yield and fruit quality, it will be important to expand and improve its manufacture and stabilize its color, which often fades under high altitude tropical conditions.
