Impact of Different Layering Times and Polybag Colors on Root and Shoot Development of Aerial Offshoots for Barhi Date Palm (Phoenix dactylifera. L) Cultivar
Year: 2024
Type: article
Abstract: This study aimed to evaluate the effect of different colors of polybags and layering time on potential root and shoot development, since the lack of root initiation and slow leaves growth are considered as a main problems for aerial offshoots handling in date palm. The study was conducted at Ghour Al-Safi, in Jordan valley on Barhi date palm cultivar at mid-October 0f 2019 to mid-October of 2021. Treatments including three layering periods (mid-October to mid-April, mid-February to mid-August, and mid-April to mid-October) and four different polyethylene bag colors (white, black, blue, brown) and transparent one (as control) were applied on aerial offshoots. Some shoot and root parameters were studied to determine the best layering time and polybag color that could increase the survival rate of aerial date palm offshoots. Root and shoot parameters were preference under blue polybag and layering time that extended from mid-October to mid-April than other treatments. Offshoots under the transparent polybag gave the lowest parameters and reflected poor rooting ability. Although polybag color played a significant role in the root ability for aerial offshoots compared with control, the root and shoot parameters data looked relatively similar between other colors. Layering period could also increase the quantity of new fronds and productive roots.
