Yield Effects of Tissue Culture Bananas in Kenya: Accounting for Selection Bias and the Role of Complementary Inputs
We analyze yield effects of tissue culture (TC) banana technology in the Kenyan small farm sector, using recent survey data and an endogenous switching regression approach. TC banana plantlets, which are free from pests and diseases, have been introduced in East Africa since the late-1990s. While field experiments show significant yield advantages over traditional banana suckers, a rigorous ass...
متن کاملWhich Culture System Is better for Chondrogenesis of Adipose-Derived Stem Cells ; Pellet or Micromass?
Background and Aims: The current study was conducted to compare the expression levels of collagen type Π and X during chondrogenesis of human adipose-derived mesenchymal stem cells (hADMSCs) pellet and micromass cultures. Materials and Methods: Extracted hADMSCs were cultured until three passages and then transferred to pellet and micromass cultures in the experimental groups of day 7 and day...
متن کاملBananas Enough for Time Travel?
This paper argues that the most famous objection to backward time travel can carry no weight. In its classic form, the objection is that backward time travel entails the occurrence of impossible things, such as auto-infanticide—and hence is itself impossible. David Lewis has rebutted the classic version of the objection: auto-infanticide is prevented by coincidences, such as time travellers sli...
متن کاملPhenotyping bananas for drought resistance
Drought has emerged as one of the major constraints in banana production. Its effects are pronounced substantially in the tropics and sub-tropics of the world due to climate change. Bananas are quite sensitive to drought; however, genotypes with "B" genome are more tolerant to abiotic stresses than those solely based on "A" genome. In particular, bananas with "ABB" genomes are more tolerant to ...
متن کاملTissue Culture
Dr. Willmer's second edition of this little book fulfills his stated purpose ... to correlate some of the numerous fragments of scattered data which have so far been obtained and to orientate them in such a way as to illustrate the more fundamental contributions which the method has made to physiological knowledge, and to show the manner in which a change of outlook has already been brought abo...
