Application Of Plant Tissue Culture In Horticultural Production
Waithaka, K (University of NairobiCollege of Agriculture and Veterinary Sciences, 1988)The term 'plant tissue culture' is normally used as a 'blanket' term to cover the cultivation of all plant parts whether a single cell, a group of cells or an organ on an artificial medium. The in vitro cultures are now ... -
Carbohydrate Traffic During Opening Of Gladiolus Florets
Waithaka, K; Dodge, LL; Reid, MS (University of NairobiCollege of Agriculture and Veterinary Sciences, 2001)The opening of gladiolus florets was accompanied by a substantial increase in fresh and dry weight and carbohydrate content of the perianth. The principal soluble carbohydrate was fructose, with substantially lower ... -
The Effect Of Conventional Methods Of Growing Tea On Yields
Magambo, MJS; Waithaka, K (University of NairobiDepartment of crop science, 1985)Tea bushes are manipulated so as to form strong woody frames with the largest possible plucking surface area. Studies on dry matter production and partitioning of tea bushes have shown that the harvest index is low in old ... -
The effect of phosphorous fertilization on growth and tuberization of sweet potato, ipomoea Batatas L.
Rashid, K; Waithaka, K (Department of Plant Science and Crop Protection, University of Nairobi, 1985)A study was conducted to investigate the effect of phosphorus fertilizer levels on the growth and tuberization of two sweet potato cultivars. P did not cause any significant influence on growth or yield of vines and tubers ... -
Flower Bulb Forcing In Kenya
Waithaka, K (University of NairobiCollege of Agriculture and Veterinary Sciences, 1986)Cut flowers are among the most important horticultural produce in Kenya for domestic and export markets. Other than carnations, roses, statice, mollucela etc., bulbous plants such as liatris, arabicum, tuberose, ornithogalum, ... -
Growth And Flowering Patterns Of Liatris Corms In Kenya
Waithaka, K (University of NairobiDepartment of plant science and crop protection, 1985)Terminal and axillary buds of Liatris corms require cold treatment for flower induction and release from dormancy. The terminal and a few axillary buds closest to the terminal one develop into flower buds after chilling. ... -
Growth And Runner Production Of Everbearing Strawberries In Kenya
Waithaka, K (University of NairobiDepartment of plant protection and crop science, 1985)Strawberry production in the tropics is hampered by lack of enough propagative material. Propagation in Kenya is mainly by crown division because the continuous short day condition in the tropics does not favour enough ... -
Growth performances of everbearing strawberries in Kenya
Waithaka, K; Ngugi, CW (University of NairobiDepartment of Crop Science, 1985)In Kenya propagation is mainly by crown division because the continuous short-day conditions favour branch crown development over runner production. Continuous crown division and flowering resulted in a decline in vegetative ... -
The Influence Of Plant Density On Dry Matter Production And Partitioning And Yield In Young Clonal Tea In Kenya
Magambo, MJS; Waithaka, K (University of NairobiDepartment of crop production, 1985)Dry matter production and partitioning and yields in clonal tea bushes planted at 3 different spacings (0.30 x 0.30 m; 0.61 x 0.61 m; and 1.22 x 1.22m) and brought into plucking at 2 different heights (0.25 m and 0.50 m) ... -

The Relationship Between N, P And K Concentrations In Sweet Potato Vines And Dry Matter Accumulation In Vines And Tuberous Roots As Influenced By P Fertilization
Reshid, K; Waithaka, K (University of NairobiDepartment of crop science, 1988)Higher N concentrations in vines of 'Musinya' and 'Gikanda' cultivars showed a positive correlation with dry matter accumulation in the vines and a negative correlation with dry matter accumulation in tuberous roots during ...
