Effect of Transplanting Date on the Phenology and Production of 4 Tomato (Lycopersicon Esculentum Mill.) Hybrids Grown Under Greenhouse

The effect of cultivar, sowing date and transplant location in field on bolting of Welsh onion (Allium fistulosumL.)

“…The JinGuan (C 1 ) and TieGanWuTong (C 7 ) cultivars could be considered early-bolting varieties, whereas the XiaHei (C 3 ) and LinBang (C 10 ) cultivars could be considered late-bolting varieties. Transplant characteristics are closely related to the bolting characteristics of plants [ 19 ]. In our experiment, because the seedling age and the environment conditions, such as AAT and EAT, during nursing were different for the different sowing date treatments, the morphological development of the seedlings was not the same on the transplant date, and thus, the sowing date has an influence on the bolting of the Welsh onion.…”

“…The Welsh onion belongs to the green plant vernalisation type, which is characterised by seedlings that must be grown to a certain age before they can sense the cold environment and begin the process of vernalisation. The characteristics of transplants also determine the establishment rate of plants and their ability to respond to low temperature [ 19 ]. Moreover, the response of plants to vernalisation is determined not only by the temperature during the vernalisation period but also by the duration of the low-temperature exposure [ 20 , 21 ], and thus, the cold requirements for vernalisation vary greatly with the genotype and the environment [ 22 ].…”
