As a cheeky weed reference, Leafs by Snoop is abbreviated across the products as "LBS," a play on buying in bulk.
The ability of source leaf phloem to take up L-[1-C]AsA, or a number of substrates related to AsA metabolism ([1-C]DHA, D-[U-C]mannose, L-[1-C]galactose and [U-C]sucrose as a reference) was tested in leaf discs of Nicotiana benthamiana, a model system for phloem uptake studies as it allows good resolution of major and minor veins [ 28].
Based on these two data sets, the principal component analysis (PCA) and band-band correlation methods were used to select significant wavelengths with no reference to leaf biochemical properties, while the partial least squares (PLS) method assessed the contribution of each narrow band to leaf biochemical content associated with each loading weight across the nitrogen and water stresses.
The experiments were novel in that three characteristic reference areas (leaf area AL, frontal projected area under flow AP, and still-air frontal projected area A0) as well as the foliage stem reference area ratio (AL/AS) were evaluated.
To do so, one to two older and three younger leaves than the reference senescing leaf (rank 0) from Aviso and Express plants grown under optimal and sub-optimal nitrogen fertilization were analyzed.
The hand serves as a visual reference for leaf size, which is also given in both metric and English units (Table 1: Best Practice 5).
Furthermore, the number of healthy leaves per shrub and stem circumference were lower around the power plants than the reference site, while leaf damage and other plant growth traits did not differ.
A second notable aspect of the Field Guide to Native Oak Species is the inclusion of the leaf reference guide at the back of the book (Stein et al. 2003).
A set of 36 cuttings (6 7 cm) were collected from the P. trichocarpa Nisqually-1 reference genotype (narrow leaf) and grown in hydroponic chambers containing ½ concentration MS solution for 48 h.
The algorithm generates an HLA alignment tree for each read based on the mapping results against an HLA reference database whose leaf nodes indicate four-digit alleles and inner nodes represent allele families to which the read could be mapped.
