Species from Aggastache genus are part of mint family (Lamiaceae)
and their flowers represent a lure for insects (bees, butterflies etc.). The common
name of hyssop comes from the plants hyssop flavour. Commercially, this plant
is considered as having culinary importance. Several varieties of this species
were selected in Canada, for their essential oil, which contains methyl chavicol.
The species was cultivated in Moldavia, as an experiment, for essential oil production.
The herb (Agastache foeniculi herba) is used for therapeutic purposes
in treating cardiovascular, nerve and gastrointestinal affections, in treating
cold, fever (North America Indies used the infusion for this intent) and as a
diaphoretic. It also has antiemetic, antibacterial and antifungal properties.
It improves throat pains and cold symptoms. The present study aimed to determine
seed germination, by using classical methods- on paper under layer, in Linhardt
dishes and in blotting paper envelopes. Seeds were 1, 2 and 3 years old. The results
show that seed germination of Agastache foeniculum (Pursh) Kuntze, is
influenced by age and external factors (temperature and light). TP (Top of Paper)
and BP (Between Paper) methods both influence the germinating faculty. |

In the experimental field of UASVM Cluj-Napoca from Jucu we performed,
between 2008-2010, a series of research on the behavior of eight varieties of marigold, in three
conditions of soil fertilization with manure. The average yearly air temperature is 10.71 ° C Jucu in
2008, 11.12 ° C in 2009 and 11.21 ° C in 2010 and during the growing season (aprilie-sept.) of 17.70 °
C 19.07 ° C and 18, 08 ° C. In terms of rainfall, 2008 was very dry (less than 150 mm from the annual
average), 2009 excessively dry (less than 250 mm annual average) and 2010 was very wet (83 mm
more than the annual average). Climatic conditions were favorable to grow marigolds.
A series of biometric measurements have been conducted on the eight varieties of marigold,
such as waist measurement of the average plant, the production of flowers and drying efficiency, the
correlation between average plant size and production.
Average plant size in eight varieties of marigold, in 2008-2010 was between 67.44 and 84.78
cm. Production of fresh flowers was between 7400 and 8507 kg / ha.
The biggest production of inflorescences was obtained from varieties of “Belezza del
Pacifico”, “Cluj 2” and “Starsem 922”, with over 9.000 kg / ha of fresh flowers. Production of
Marigold is strongly influenced by genotype and fertilization. The average yield of drying was 6 / 1.
Between the average height of marigold plant and production there's a direct link. The increase
of production is influenced by the average size of marigold plant. |

Agastache foeniculum has its origins in North-America. In Europe has been
planted for the first time as a decorative plant in flower gardens (Small E., 2006). For species
Agastache foeniculum varies common names have been used: Anise hyssop, Blue giant
hyssop, Giant fennel hyssop (Allen Gary, The Herbalist In The Kitchen, 2007). Multiplication
of the species can be achieved by transplantation of the seedlings in cellular packages or small
containers, 15 to 20 days after seeding (Armitage A.M. and Laushman J.M., 2003).
Multiplication of the species can be achieved by transplantation of the seedlings in
cellular packages or small containers, 15 to 20 days after seeding. The most recommended
temperatures for young plants are bellow 15°C. The plants will bloom at 12-16 weeks after
seeding (Armitage A.M. and Laushman J.M., 2003).
Separation of the stalks is performed in the spring from mature plants, over 2 or 3
years old. Sowing is done by using young stalks from the base potted in pots in the
greenhouse in light shadow. In about 3 weeks the young plants will have their roots formed
and they will be ready to be planted in the field in the summer (Falticeanu Marcela, Munteanu
N., 2010).
During the seedling the experiment took place in the greenhouse, in plastic trays,
throughout April and May at temperatures over 20°C. First observations have been made after
7 days when the first 2 leaves sprouted, followed by observations every 7 days as the other
leaves were forming. For observations, over 80 plants have been chosen to be measured
targeting their hight and the number of leaves.
The texture of the soil for obtaining good seedlings of Agastache foeniculum (Pursh) Kuntze
has to be clay like.
The time needed to form the first pair of leaves at 20°C is 7 days. The next leaves are
formed at aprox. the same period of time, 7 days.
To obtain the seedling of Agastache foeniculum (Pursh) Kuntze in the greenhouse
during April and May we recommend that the temperature should be over 20°C. |

In this paper we present results of the research made between 2008-2010 on the influence of
cultivation, density and fertilization on the plant’s morphology and leaf production.
Experiences had been located in the experimental field of Jucu, CJ. We took four cultivation of
artichokes in the study: “Unirea”, “Violet”, “Agrosel 656” and “Chisinau”. They were placed in the
experimental field of Jucu - Cluj, made in two densities (3.57 pl/sqm and 2.38 pl/sqm) and three levels
of fertilization (unfertilized, fertilized with 20 t/ha farmyard manure and 40 t/ha manure in the fall
plowing). |
