يعد القرنفل في البيوت الزجاجية و البلاستيكية أحد أهم محاصيل أزهار القطف في سورية و يعول على الإنتاج في سد احتياجات السوق المحلي، و هناك محاولات جادة للتصدير إلى الأسواق العربية و الأوروبية. نتيجة معاناة المنتجين لهذا المحصول من ظاهرة تقزم النباتات، و صغر حجم الأزهار في فصل الصيف فقد هدف هذا البحث إلى محاولة معرفة أسباب هذه الظاهرة بدراسة تأثير درجات الحرارة الليلية المرتفعة بالمقارنة مع الحرارة النهارية في تطور الأعضاء الزهرية في القرنفل. و شملت أربع معاملات ، White Sim نُفِذت التجربة باستخدام نباتات القرنفل القياسي الصنف حرارية و كرر كلٌ منها أربع مرات. كانت جميع النباتات في جميع المعاملات حتى نهاية التجربة تنمو نهاراً (الساعة 8 حتى 17 ) في البيت الزجاجي ضمن ظروف ضوئية و حرارية واحدة.
Carnation is one of the most important crop for cut flowers not only in Syria but all over the world. The producers in Syria and in other countries are suffering during the seasons of hot temperature from dwarfing of the plants and the production of small flowers. The work conducted here was to investigate the effect of high temperature on flower development and morphology.

The results of this study showed the important role of the light
intensity compared with the light exposure time on coloring the new
formed leaves, also this study had showed that the leaves are not
affected by the different temperatures, and also
that these plants showed
a decrease in the different pigment substances in close proportions.
Concerning the amount of proteins, the results have shown main
differences in the protein bands between the mutated and the natural
species, but we have found a decrease in the amount of proteins in the
mutated species than in natural species.
The effect of temperature on the development of the predator Hippodamia variegata
(Coleoptera:Coccinellidae) reared on the green peach aphid Myzus persicae Sulzer
(Homoptera:Aphididae) was determined at five constant temperatures (15, 20, 25, 30
a
nd 35)°C under laboratory conditions. The present study was conducted at Latakia
Agricultural Research Center during 2015 and 2016. This study aimed to determine
the impact of temperature on the development of the predator H. variegata to
identify the suitable temperature for rearing this predator. The duration (days) and
survival (%) were measured for this predator. Results showed that temperature had
a significant effect on the development of H. variegata immature stages, whereas
the development time from larvae to adult decreased with increasing temperature
at thermal range (15-35)°C. The longest larval developmental duration was 24.84 days
at 15°C, and the shortest duration was 4 days at 35°C. Also, the shortest pupal
duration was one day at 35°C and the longest period was 9.84 days at 15°C. The
lowest developmental time from eggs hatching to emergence of adults was 6 days
at 35°C, while the longest developmental time was 36.84 days at 15°C. Also the
ratio of larval survival was affected by temperature, this ratio was (26%, 52%,
77%, 34%, 4%) at (15, 20, 25, 30 and 35)°C respectively. The results of statistical
analysis showed that there were significant differences between the five constant
temperatures in all studied biological characteristics, and the temperature 25°C was
suitable for a successful rearing of the predator H. variegata.
Collisions induced absorption spectra of pure oxygen and gaseous mixtures
of oxygen and nitrogen were measured at laboratory and studied, in the region
of 1.06 μm, using Cary 5000 spectrophotometer, and White absorption gas cell
with a path length
fixed at 9.6 m. The mixing ratio of oxygen in nitrogen were
20%, 50% and 80%, at temperature 298, 323, 348, 373 K and pressures
between 1 and 25 bar. The absorption band was centered at 1.06 μm, and
raised as a wide continuum absorption, and did not show any rotational
structure.
In this study, the effect of temperature on volume strains in three
types of local clay soils was studied after adding different percentages of
sand for each soil (10%-20%-30%40%-50%) when temperatures change
from (20-60)° C to be used as liners i
n solid waste landfill sites . The
results of the study showed that the mixing of sand with the clay played a
key role in reducing the magnitude of volume strains between (24-27%)
of the value of strains.
This paper concerns the mathematical model of Ignaczak kind for
