Abstract

This investigation Elimed the increase of fruit
yield and capsaicin contlent by studying the effects
of water regimes and chemical cytokinens spraying on
growth. fruiting and chemical composition of Capsicum
aIUlUum L.
T,h.eexperiments were carried out during two successive
years of 1981 and 1982 at the Experimental Station,
Faculty of Agriculture at Moshtohor. Zagazig University.
In a split plot design 6 water reg~es involving
quantity of water and water supply intervalS were in
the main plots. The sub-plots treatments included the
application of two growth regulators namely (PBA) (6(
benzylamino)9(2-tetranyDROPyronyl) 9.H purine) and NPA
(6(benzylamino)9(2-tetrahyDROPyranyl)4H nicotinamide).
The most important results are :
1. The minimum amount of water supply produced the
highest number of branches on pepper plants.
2. Maximum amount of watering at 5-day interval gave
the least number of branches.
3. Water stress due to longer intervals of irrigation
serioUSly decreased the number of fruits carried on
the plant.
4. Adequate and high amounts of water supply significantly
increased fruiting.
5. Moderate amounts of water. at snort intervals as 5-da.ys
economically produced a good crop in both number and fresh weight.6. Decreasing water supply may increase the fresh weights
of vegetative organs but fruiting was seriously decreased.
7. The highest percentage of dry matter of fruits was
corncided with irrigation every 10 days.
8. Spraying PBA at 100 ppm increased the number of branches
especially those subjected to drougbt conditions.
9. Application of FBA increased fruit-set and fresh
weigh t of fruits.
10. The application of FBA may improved the flower and
fruit DROP in crops grown under drought conditions.
11. NFA at the proposed concentrations baS deteriorating
effects on fruit-set of pepper.
12. Pepper plants can be grown under moderate amounts
of water as 4)00 Y)/feddan and sprayed by 100 ppm
of PBA for better yield.
1). Shortage of water supply as (quantity or loneer
intervals of irrigation increased capsaicin ingredient
in fruits of pepper.
14. PBA at 100 ppm generally increased capsaicin content
except with plants subjected to long intervals of
irrigation.
15. PBA may be applied to increase capsaicin in fruits of
plant grown under high or moderate water regimes.
16. The concentration of PBA as 200 ppm decreased capsaicin
in pepper fruits by 82 % for plants grown under long
intervals of irrigation.
17. NPA increased the capsaicin only with plants grown
under frequent and abundant water supply.
18. Carbohydrate percentages were high in leaves of plants
grow under moderate amounts of water, and increased by
PHA ~pplication.
19. Treatment (A) with 200 ppm of PEA or NPA increased the
percentages of (a) and (b) chlorophyll.
