“…Idso et al (1989) also observed similar moderating effect of CO2 enrichment in Azolla sp. On the contrary, Reddy et al (1998) reported that high temperature during the critical stages of plant growth nullified the effect of C02.…”

We studied the growth of Anabaena fertilissima under graded C 0 2 and temperature conditions to assess its suitability as a C02 scavenger for carbon recycling. A. fertilissima reached maximum growth at 6% C02, but growth declined above this C 0 2 level; yet, at no C 0 2 concentration growth was less than that at ambient C02. High temperature (>30°C) reduced growth of the cyanobacterium, but presence of elevated (6%) C02 lessened the intensity of that reduced growth. High temperature also reduced biomass, pigments, total protein, and nitrogen fixation, but elevated C 0 2 significantly moderated this negative effect. Elevated C02 reduced I4co2 uptake by 50% at 30°C and >44% at higher temperatures compared to uptake at ambient C 0 2 at 30°C. Similarly, carbonic anhydrase activity also showed inhibition at high C02.

“…Temperature appears positively correlated with SD (Ferris et al, 1996;Reddy et al, 1998;; but see Apple et al, 2000), a likely consequence of enhanced water stress. Temperature may also affect SI (Ferris et al, 1996;, suggesting an in¯uence on stomatal initiation.…”

“…Temperature may also affect SI (Ferris et al, 1996;, suggesting an in¯uence on stomatal initiation. Reddy et al (1998), however, found no response. The in¯uence of temperature on stomatal initiation may be inconsequential, though, as most plants partially normalize for¯uctuating temperatures by adjusting the timing of leaf development, and so the temperature at which stomata form remains fairly constant .…”

“…Suggested solutions to these problems were selection of tolerant cultivars, effective and timely insect and weed control, adequate irrigation regime, use of proper crop monitoring techniques and application of plant growth regulators. Reddy et al (1998) found that when Upland cotton Gossypium hirsutum cv. DPL-51 was grown in naturally lit plant growth chambers at 30/22°C day/night temperatures from sowing until floral bud production, and at 20/12, 25/17, 30/22, 35/27 and 40/32°C for 42 d after floral bud production, fruit retention was severely curtailed at the 2 higher temperatures compared with 30/22°C.…”

Understanding the impact that climatic factors have on cotton production may help physiologists to determine possible control mechanisms which influence the flowering of cotton plants. This study was conducted to investigate the nature of the effects of climatic factors prevailing prior and subsequent to either flowering or boll setting on flower and boll production and retention in Egyptian cotton Gossypium barbadense L. Two uniform field trials using the cotton cultivated variety Giza 75 were carried out at the Agricultural Research Center, Giza, Egypt. Randomly chosen plants were used to record daily numbers of flowers and bolls during the production stage (68 d in Season I and 62 d in Season II). The daily records of the climatic factors (air temperature, diurnal temperature range, evaporation, soil surface temperature, sunshine duration, and humidity) were recorded during the entire period of production and also for the 15 d periods before and after anthesis. The effects of climatic factors on flower and boll production were quantified in non-limiting management techniques. Relationships in the form of simple and multiple correlations were computed between climatic factors and flower and boll production and retention. The data indicated that evaporation, minimum humidity and sunshine duration were the most effective climatic factors during preceding and succeeding periods on boll production and retention. There was a negative correlation between flower and boll production and either evaporation or sunshine duration, while the same correlation with minimum humidity was positive. Thus, it appeared that low evaporation rate, reduced sunshine duration and high humidity would enhance flower and boll formation. Accordingly, the deleterious effects of climatic factors on cotton production could be minimized through applying appropriate production practices, which would control and adjust the impact of these factors and thus potentially lead to an important improvement in cotton yield in Egypt.KEY WORDS: Boll retention · Evaporation · Flower and boll production · Humidity · Sunshine duration · TemperatureResale or republication not permitted without written consent of the publisher
