However, certain metabolites are toxic in nature, which necessitates the toxicological evaluation of natural products, which includes testing of plants for cytotoxic, genotoxic, and mutagenic potentials [ 7, 8].
Amended regulations may require standard operating procedures for both plant exporters and importers, including plant inspection and testing, detailed recordkeeping, and small-scale field testing of plants excluded for importation pending risk assessment (if this proposed exclusion category is in fact established by regulation amendments) (USDA APHIS 2004).
There is no substitute for detailed examination of plants and soil conditions in the field, followed by simple fertilizer tests, quick tests of plant tissues, and analysis of soils and plants.
Furthermore, the lack produces uncertainties of the sensitivity tests of plant responses to doubled CO2 concentration and increased air temperature conditions.
According to conventional tests of plant injury and fast chlorophyll fluorescence rise kinetics, four different croftonweed populations collected from South China were successfully classified into three categories by exposing whole plants to heat treatment at 40 °C: sensitive, intermediate, tolerant.
Tests of plant traits indicated that the crayfish responded primarily to plant structure, the apple snails primarily to plant chemistry, and that plant protein concentration played no detectable role.
Node of first fruiting branch (NFFB): Used as a test of plant maturity and development by the examination of the maintem node (counted from the first true leaf) of the first fruiting branch [ 20].
There were also tests of planting weapons in which new members had to participate in order to show their loyalty to the CRASH unit.
Besides, one can test the validity of interpretation by traditional progeny tests of plants raised from tissue culture from sectors as in Nicotiana and/or by precursor analysis as done in Antirrhinum.
In parallel tests of plants under long days or short days, the RfBP gene was highly expressed and a substantial amount of the RfBP protein was produced in leaves of RfBP+ in contrast to the absence of gene expression and protein production in the WT plant.
