Abstract:
This study aimed to investigate the adaptation of the Arecaceae family, Trachycarpus
fortunei, Trachycarpus vagnerianus, Jubaea chilensis and Washingtonia robusta species to the
harsh and continental climate conditions. The results of the study provided insight into the
competition and germination rates of these palms in harsh climate conditions.
Keywords:
Arecaceae, palm species, seed germination, continental climate, adaptation
Introduction
.
The palmadosh family (Arecaceae) has a worldwide distribution, being mostly common in
tropical and subtropical regions. However, some representatives can also adapt to harsh
continental climates. Among others, species such as Trachycarpus fortunei, Trachycarpus
wagnerianus, Jubaea chilensis and Washingtonia robusta are of interest in terms of frost
resistance and seed germination. This article analyzes the flexibility characteristics of the species
of these palms.
Methods
The following techniques were used during the study:
1.Seed germination assessment-the seeds of each species were collected, and their germination
was observed in laboratory conditions under different humidity and temperature conditions.
2.Climate Adaptability Test-plants are planted in natural conditions, their frost resistance level
and vegetation status were observed.
3.Statistical analysis-the results were processed using mathematical and statistical methods and
conclusions were drawn on the flexibility of each species.
Further sections cover research results and conclusions

A representative of the palmadosh family, the trachycarpus seed (Table 1) was planted in 3
different variants at a depth of 0.5 – 1 cm, 1 – 1.5 cm, 1.5 – 2 cm. In the course of studies,
according to the results of observations, the highest rate of germination was observed in seeds
planted to a depth of 1 – 1.5 cm. The tensile state achieved a result above 70%.

according to the results of observations of the experiment, we can see a more effective result in
the germination (42%) and growth dynamics (3.1 – 3.8 cm) in palm seeds planted to a depth of 2
options(0.5 – 1 cm and 1.5 – 2).
We can also see a more effective result in 1.3 (0.5 – 1 cm and 1.5 – 2 ) options compared to 2
options(1-1.5 cm) in germination(42 %) and growth dynamics (3.1-3.8 cm) in palm seeds
planted to a depth.

ative of the palmadosh family is Fenik (phoenix canariensis), when sown in 3 different variants
(Table 3), the germination of seeds sown to a depth of 1.5-2.0 CM was achieved by a slightly
higher rate of 86% compared to those of other variants. The germination of a different sign of
Phoenix from other species was found to be somewhat premature when compared to other
species

It was observed that even the Canarian (jubaea chilensis) seed from the palmadosh Family
(Table 4), when planted in 3 different variants, the optimal selected depth is 1.5-2 cm for us. In
this, the germination rate of the seed was 86%.
It was observed that the most optimal selected depth for us is 1.5-2 cm when sowing seeds of the
Chamerops (chamaerops) type, which are representatives of the palmadosh family, also in 3
different variants (Table 5). In this, the germination rate of the seed was 86%

Another representative of the family showed a relatively more effective result (57%) of seeds
planted on the Earth's surface even with low-spread butya (butia) seeds sown in 3 different
variants (Table 6), 0.5 – 1.0 cm, 1.0 – 1.5 cm, 1.5 – 2.0 CM, the closest 0.5 cm to the Earth's
surface regardless of seed size.

Conclusion
Of the representatives of the palmadosh family, Canaries (jubaea chilensis), Chamerops
(chamaerops) and Phoenix (phoenix canariensis) in laboratory conditions, we can observe in the
table that the most effective result of germination is achieved when planting a depth of 1.5-2.0
CM in the canvas. Trachycarpus, one of the representatives of this family, as well as Washington
seeds, observed that seeds 1.0-1.5 cm deep showed a satisfactory result when they were observed
to be germinated. The representative of the palmadoshs in Butya showed the result that we did
not expect in terms of germination of seeds planted in the depth of the ground to a size of 0.5 cm.
Because, in terms of size and weight of seeds of this species (for example, one grain of
Palmadosh Butya species has an average weight of 0.67 grams, the volume is in the range of 2.0
– 2.4 cm), the palmadosh family is large in size and weight is greater than the seeds of other
species we have used in our experiment.
