periderm การใช้

• Those three tissues form the periderm, which replaces the epidermis in function.
• They initiate mining in the periderm but later feed exclusively in the cortex.
• Suberin is found in the phellem layer of the periderm ( or cork ).
• Within the periderm are lenticels, which form during the production of the first periderm layer.
• Within the periderm are lenticels, which form during the production of the first periderm layer.
• Additional structural support was provided in lycophytes by a special periderm tissue in the outer cortex.
• Areas of loosely packed cells in the periderm that function in gas exchange are called lenticels.
• Curing is a technique done to toughen up the outer layer of skin ( periderm ).
• The mines are formed in the living periderm of the host causing superficial injury to the tree.
• Moisture is stored in the cortex of the roots, which is protected by a thin periderm.
• The colonies are covered with chitinous periderm and can be either prostrate or erect with weak or sympodial branching.
• At this point, the cork cambium begins to form the periderm, consisting of protective cork cells containing suberin.
• They feed in the periderm, as it does when it occurs in the absence of congeners on white ash.
• Woody stems and some other stem structures produce a secondary covering called the periderm that replaces the epidermis as the protective covering.
• In some colonial polyps, a chitinous periderm gives support and some protection to the connecting sections and to the lower parts of individual polyps.
• A "'plant cuticle "'is a protecting film covering the leaves, young shoots and other aerial plant organs without periderm.
• "The periderm is much tougher in this area, so it won't deteriorate as fast from dog urine, " he said.
• Many species within the genus, including " flanaganii ", have photosynthetic modified stems that lack, or have delayed development of, periderm.
• In more severe cases, " H . solani " causes weight loss in potatoes and creates lesions in the periderm, creating entry points for other tuber pathogens.
• Sporulation occurs in endosperm tissue until the entire kernel is converted into a sorus consisting of a dark brown to black mass of teliospores covered by a modified periderm, which is thin and papery.
