A research in English on the study conducted at the Faculty of Agriculture in Kafr El-Sheikh during the years 93, 94, 1995 with the aim of producing mono plants by planting Mutok and eggs of caucus percussion plants, the Alexandrian variety. The study included two main parts and egg cultivation. The first is to study the effect of some sugar levels and 2.4-d, as well as the interaction between them on the production of mono plants from the cultivation of mottals, where sucrose was used at levels of 30, 60, 90, 120, 150 and 150 g / l, and used 2.4-d at a concentration of 0.1, 1.0, 2.5, 5 mg / liter and among the most important results obtained with regard to the production of callus and the distinction of plants that in terms of the influence of sugar levels and the effect of the concentration of 2.4-d and the effect of the interaction between sucrose, 2.4-d
As for the second experiment, it was conducted to study the effect of some concentrations of articles 2.4 - d, chitin (1, 2.5, 5 mg / l) on the production of callus and the distinction of plants resulting from the cultivation of zucchini squash tokens. The diameter of the cup and the distinction of plants were highly significant differences with respect to the number of callus produced for plants, the number of plants per dish, the number of plants per callus and secondly the production of mono plants by planting eggs, the first experiment was conducted to study the effect of treatment at low temperatures (4 ° C for zero, 2, 4, 8, days) and the focus of 2.4-d and their interaction on the production of mono plants from the cultivation of zucchini squash eggs and the most important results for the effect of low temperature treatment gave
Untreated eggs at low temperatures The largest number of eggs produced for plants and the largest number of plants per 100 eggs Production of untreated or treated eggs at a temperature of 4 m for a period of 8 days The largest number of callus per 100 eggs The number of plants per egg was not affected by different cold periods and also effects Different for each of the concentration of 2.4 - d and the effect of the interaction between the coldness factors and 2.4 - d. The second experiment was conducted to study the effect of the interaction between some concentrations of 2.4 - d and chitin (0.01, 0.1, 1.0 mg / l) on the production of mono plants from the cultivation of squash squash eggs and thirdly Cytological studies examined the peaks of development of 20 plants resulting from the cultivation of mottok and resulting from the cultivation of eggs under the optical microscope.
