the formation of fruit intrinsic quality. The kind and content of fatty acids are the
important indexes of fruit quality of industrial oil plants.
1.1.2.3 Evaluation of Stress Resistance of Industrial Oil Plant Germ
Resources
It mainly includes the adaptability and resistance of industrial oil plants to diseases,
pests, low temperature, high temperature, drought, waterlogging, saline-alkali soil,
heavy metal stress and so on.
The vast territory of our country, diverse ecological environment have created
rich industrial oil energy plant resources [19]. In the long process of coevolution
with the environment, each kind of industrial oil plant has formed a unique suitable
environment, but the industrial oil energy plants in nature do not always live under
suitable environmental conditions, and often encounter diseases and insects. Cold,
drought, salt and other adverse environmental factors, this industrial oil energy plant
survival or growth of the environment is called adversity, also known as stress. The
stress of industrial oil plants can be divided into biological stress and abiotic stress.
Biological stress mainly includes disease, pest, grass damage and so on. Abiotic
stress includes low temperature, high temperature, drought, waterlogging, saline and
alkali soil, heavy metal and so on. Some industrial oil and energy plants cannot adapt
to these bad environments. Some plants can adapt to these environments, and this
adaptability and resistance to bad environment is called the resistance (tolerance)
of industrial oil plants to the adverse environmental resistance, which leads to the
reduction of production or quality, or even the inability to survive, but some plants
can adapt to these environments.
The evaluation of stress resistance mainly refers to the systematic identification
and gene analysis of adverse environmental factors, such as low temperature, high
temperature, waterlogging, drought, saline-alkali soil, acid soil, excess or lack of
individual elements in soil, resistance to diseases and insect pests, tolerance and
gene analysis.
Disease identification: there are many methods for identification of plant disease resistance, which can be divided into population level, individual level, tissue
level and molecular level according to the different levels of non-identification [20].
According to the place of identification, it can be divided into field identification and
laboratory identification, and plant materials can be divided into adult identification,
seedling identification and retirement identification. In order to evaluate the disease
resistance of industrial oil plant germplasm resources quickly and comprehensively,
the disease resistance should be identified according to the different requirements
of disease, infection type, epidemiological standard and yield, and various methods
should be used flexibly to give full play to the advantages of various identification
methods.
Field identification: it is the most basic identification method and the main basis
for evaluating the identification results of other methods. Field identification needs
to be tested in an ad hoc disease resistance identification nursery, according to the
