Explanation:
New roots are primarily white. When choosing a tree for transplantation, the arborist should pay close attention to the roots since the tree's capacity to survive on stored carbohydrates and take up water right away will be crucial to its success in its new habitat. A good measure of root health is whiteness. Verifying that the roots are correctly positioned and do not round the stem is also crucial.
Explanation:
The size of a tree is the main factor that determines its value in the CTLA trunk formula method. It was the Council of Tree and Landscape Appraisers that developed the CTLA method. It's critical to distinguish between the CTLA's trunk formula approach and its more comprehensive tree health evaluation rubric, the CTLA methodology. When evaluating a tree, the CTLA technique adds ratings about species, location, size, and condition.
Explanation:
Hooker's pitcher-plant, Nepenthes x hookeriana, is a hybrid. The x, which shouldn't be italicized, indicates this. A plant crossed between two different species is called a hybrid. A hybrid is usually created from plants that belong to the same genus.
Explanation:
Naturalized species are non-indigenous species that have established themselves in a certain location and can reproduce on their own. A species that has been transported to a new location is referred to as introduced. An introduced species is said to be naturalized if it is successful and survives for several generations without assistance from humans. When an invasive species is brought into a new habitat, it soon becomes dominant, displacing native species and upsetting the ecosystem. At last, a native species inhabits its natural habitat, to which it has developed complete adaptations.
Explanation:
Class, order, family, and genus are arranged from general to specific. Kingdom, phylum (also known as division), class, order, family, genus, and specific epithet make up the entire taxonomic system. To remember these concepts, arborists frequently employ mnemonic devices, such as Keeping Precious Creatures Organized For Grumpy Scientists. All trees belong to the kingdom of plants, which is the highest classification level. Trees are classified into two groups at the phylum level: those with vascular tissue and those without. Dicotyledons, which contain two seeds per leaf, and monocotyledons, which have one, are the two groups of trees. Next, trees are further separated based on family and order. Similar fruit and/or flowers are typically seen on trees belonging to the same family. The species name is made up of the last two components, genus and specific epithet.
Explanation:
Maple, ash, dogwood, and horse are the principal genera of trees with opposing leaf arrangements. The acronym MAD Horse, which stands for maple, ash, dogwood, and horse chestnut, is a common way for arborists to remember this knowledge. When a tree has complex leaves, the arborist should identify leaf and bud configurations that are opposite and alternate based on the location of entire leaves rather than leaflets. When leaves are arranged in an opposing pattern, they appear at the same location on either side of the stem. Although there are leaves on both sides of the stem in the alternating leaf arrangement, they appear at various points along the stem's length.
Explanation:
The ability of a tree to tolerate excessive heat or cold as well as other unfavorable circumstances like drought and flooding is known as hardiness. When determining plant hardiness, moderate and temperate temperatures are not taken into account. While temperature changes within the permitted range typically do not harm plants, they can nevertheless have an impact on physiological processes, temperature extremes are generally harmful to plants. Hardiness is a quality that is frequently disregarded while choosing trees for transplantation. To enhance arborists' capacity to choose suitably hardy trees, the U.S. The National Arboretum has produced several maps showing North America's different hardiness zones.
Explanation:
In terms of plant care, vitality refers to a plant's capacity to thrive in a specific environment, whereas vigor is the genetic capacity of the plant to withstand stress. Despite their close relationship, these two phrases have slightly different meanings. Vitality is the degree to which a plant flourishes, whereas vigor is the capacity to withstand biotic and abiotic stresses. In other words, vigor is tied to a plant's survival, whereas vitality is related to a plant's growth.
Explanation:
A variety is a subspecies that naturally breeds to have a particular attribute that sets it apart from the other members of the species. Conversely, forma are closely related groups within a species that share a common geographic location and occur naturally but differ somewhat in certain aspects. For example, the form of a given species can provide blooms with varying colors. While a subspecies shares the same geographic location and occurs naturally with other members of the species, it differs even more from those other members. Last but not least, cultivars are unique plants within their species that need human labor to develop and exhibit the desired characteristics.
Explanation:
A cultivar is a type of plant that requires human care and cultivation to maintain a certain characteristic. Put another way, asexual propagation is necessary for these plants. Cloned animals with the same genes will be the result of this cultivation. Conversely, a variety will inherently breed with a characteristic that sets it apart from other individuals in its species. Human intervention is not necessary to create a variation. Plants known as forma exhibit subtle differences from other members of their species. For example, compared to other comparable plants, a form may respond to environmental conditions marginally better or worse. Forma are found throughout nature. Although a subspecies also exists in nature, it differs greatly from other members of its species.
Explanation:
A monoculture is an extensive planting of the same species across a large area. Because monocultures are simple to plant, many landscape designers do so, yet the environmental effects can be severe. The trees are more vulnerable to disease and pest infestations when there is less variation. A self-sustaining variety of plants in a specific location is called a permaculture. A plant with only one seed leaf, such as a grass or palm, is called a monocot. A creature or material that causes sickness is called a pathogen.
