Plantago lanceolata L. növünün ex situ və in situ şəraitində ekoloji-anatomik xüsusiyyətlərinin təhlili

The study analyzed the anatomical features of Plantago lanceolata in situ and ex situ conditions.Transverse sections of the samples were analyzed by optical means after placement in temporary and permanent preparations.Anatomical transverse sections were obtained from the leaf, rosette part and root and analyzed as a result of histological staining.As a result, it was established that various tissues are formed in these organs and in the plant as a whole and which adaptations and changes they have depending on the environment in which they spread.As a result of comparative anatomical studies on Plantago lanceolata samples, it was found that the entire tissue complex in the plant taken from in situ conditions is more conservative.In the sample grown in ex situ conditions, the cortex part of the root is more voluminous, the amount of phellem, phellogen and phelloderm cells in the periderm is less.On the contrary, in the in situ sample the central cylinder is better developed.It can be noted that in the in situ sample, the leaf mesophyll is relatively thin, the main parenchyma tissue is more densely located, and in the main central vessel, the number of small vascular bundles is higher, and the number of xylem tubes and sclerenchyma cells is relatively higher.
