Kernel Growth

The response of rate and duration of kernel dry matter accumulation to temperatures in the range 10–25 °C was studied for two maize (Zea mays L.) hybrids grown under controlled-environment conditions. Kernel growth rates during the period of linear kernel growth increased linearly with temperature (b = 0.3 mg kernel−1 d−1 °C−1). Kernel dry weight at physiological maturity varied little among temperature treatments because the increase in kernel growth rate with increase in temperature was associated with a decline in the duration of kernel growth proportional to the increase in kernel growth rate.Key words: Zea mays L, period of linear kernel dry matter accumulation, controlled-environment conditions, kernel growth rate

Routine Handling

Maize (Zea mays L. cv. XL45) plants were grown from seed in controlled-environment rooms. Twice-daily weighings of the plants and containers for 7 days reduced height, and removing plants from the rooms for two 20-min periods daily for 7 days gave significant reductions in stem and leaf dry weights and total leaf area. Transpiration rates were not affected by either of these treatments. Short-term removal from the rooms (up to 10 min daily) produced no significant reductions in plant characteristics. Measuring leaf lengths daily for 10 days resulted in significant reductions in stem dry weight and plant height. It is suggested that control plants should always be subjected to the same degree of handling as treated plants.

This research was aimed at understanding the corn plant using plastic covers. The above mentioned plant was grown in plastic covers that have colours (transparent, red, green, and blue) and without plastic covers. This research was carried out in the Faculty of Agriculture, IPB from the month of May to June 2008. It was implemented using the Completely Randomized Design with three repetitions. The results of the research show that light intensity was higher in the plant that was not enclosed in the plastic covers. Generally, the research shows that the corn plant that was in the plastic covers is better than that one without plastic covers. The use of a plastic cover helps increases the height of the corn plant and the leaves. Chlorophyll a and Chlorophyll b are higher in the corn plant that was not in the plastic covers. The results of the research also indicate that transparent and red plastic covers have better responses compared to plastic covers with blue and green colors.

Rate Of Leaf Appearance

Rates of leaf appearance were evaluated for three maize (Zea mays L.) hybrids grown at two day/night temperatures (20/17 °C and 30/27 °C) in environmentally controlled growth facilities, and for 10 maize hybrids grown in the field. Differences in rate of leaf appearance occurred among genotypes and among phases of development for maize hybrids grown both under controlled-environment and field conditions. Differences in mean rate of leaf appearance between two hybrids common to both experiments were approximately 15% in both the field and the controlled-environment experiments. In addition, hybrid × phase-of-development interactions were highly significant.Key words: Zea mays L., rate of development, temperature, genotype × phase-of-development interaction
