Variety traits
Lagenaria siceraria (Molina) Standl.
The tolerance of bottle gourd to abiotic stresses is a critical breeding trait that determines yield stability and the effectiveness of the crop as a rootstock for other cucurbits.
In the reference 3 varieties crop Calabash, where this is mentioned in the description.
The evaluation of bottle gourd tolerance to drought, salinity, and temperature fluctuations is based on comparing the morphophysiological indicators of genotypes under control and stress conditions. Calculated yield indices such as SSI, STI, MP, and TOL are used, as well as physiological markers: relative membrane electrical conductivity, gas exchange parameters, photosystem II efficiency, and the content of proline or malondialdehyde.
High tolerance is characterized by a minimal decrease in fruit yield per plant (FYPP) and biomass stability under stress, whereas low tolerance manifests in a high stress susceptibility index and cell membrane damage. For bottle gourd, this trait is particularly important when selecting rootstocks, as it directly ensures the resilience of the scion to adverse soil and climatic factors.
