Abstract:
Experiment was carried out at Agro Climate Research Centre, Tamil Nadu Agricultural University, Coimbatore, during October 2018 – March, 2019 to understand horse purslane response to elevated temperature in order to manage them during under future climate scenarios. The experiment was carried out under pot culture mode in Climate Control Chamber with six treatments by Factorial completely randomized design. Each treatment was the combination of one temperature and one moisture level. Three temperature levels viz., ambient (0 °C), elevated +2 °C and elevated +4 °C three moisture and levels viz., supply of moisture at 100 per cent, 140 per cent and 60 per cent ET of previous day. Horse purslane has high reproduction and efficient seed dispersal mechanisms on +2 °C elevated temperature and excess moisture when compared to ambient temperature and elevated +4 °C. Even under drought condition the treatment of elevated temperature performing better than the ambient temperature. From this experimentation, it is concluded that Trianthema portulacastrum will grow vigorously and efficiently utilise the resources even under elevated temperature and moisture stress condition in the cropped field.
