Effect of nursery regimes and establishment irrigation on root development ofLotuscreticus seedlings following transplanting

Effects of irrigation and air humidity preconditioning on water relations, growth and survival of Rosmarinus officinalis plants during and after transplanting

“…For such purposes, the use of wild Mediterranean plant species such as Rosmarinus officinalis may be an interesting solution because of their strong resistance to environmental conditions (Savé et al, 1993;S ! anchezBlanco et al, 1998;Franco et al, 2001). Nevertheless, the transplant and establishment phases are critical for success in revegetation and landscaping projects (Whitcomb, 1986), and those plants that leave the nursery with a greater ability to function in adverse conditions, will stand a greater chance of survival in field conditions.…”

Root System Response to Drought and Salinity: Root Distribution and Water Transport

“…The distribution of assimilates from the aerial part to the root system in water stress situations has been observed by several authors in different species, such as Capsicum annuum (Davies et al 2002;Kulkarni and Phalke 2009;Shao et al 2010), Lonicera implexa , Lotus creticus (Franco et al 2001;Bañón et al 2004), Lupinus havardii (Niu et al 2007), Myrtus communis (Bañón et al 2002), Nerium oleander Niu et al 2008), Opuntia ficus-indica and Opuntia robusta (Snyman 2004 Franco et al 2008), Limonium cossonianum (Franco et al 2002) and Argyranthemum coronopifolium (De Herralde et al 1998).…”

“…Processes of osmotic adjustment in roots through the active accumulation of organic solutes from the aerial part would alter the physical support, strengthen the roots and lessen the possibility of breaking during transplanting . In this sense, moderate deficit irrigation in nursery conditions would improve plant resistance to water-deficit situations in plants grown in field conditions after transplanting (Franco et al 2001). This behaviour was also seen to be related to the reordering of the assimilate gradient as the flow of solutes towards the roots intensified.…”

“…The hardening of roots, as revealed by an increased percentage of brown roots at lower irrigation rates in Lotus creticus (Franco et al 2001) and Limonium cossonianum (Franco et al 2002), is of great interest for producing seedlings that are better adapted to drought stress after transplantation. The change in colour from white to brown is associated with suberisation of the exodermis and may reflect a metacutisation process, a process of lignification and suberisation that results in a resting root being protected against significant fluctuations in environmental conditions, including drought, and renders it capable of regrowth when conditions improve.…”

Wild geophytes of ornamental interest in the native flora of southern Italy

“…Over the last decade, a growing interest has emerged for wildspecies and wild-flowers (De Herralde et al, 1998;Cabot and Travesa, 2000;Franco et al, 2001;Martìnez-Sànchez et al, 2003).…”
