  Indices of tomato seedling quality maintenance level after production before field trans-planting were studied through simulated experiments, small-scale operation, indoor analyses and measurements, and field observation. The results showed that under simulated storage and shipment conditions, seedling quality change under different durations (days) of shipment and storage was correlated significantly or even very significantly with certain physiological and morphological indices. When various indices meas...

  This paper analyzed error sources on Abbe Refractometer measurement which is a conventional method for free water and bound water in plant tissues. The measurement method was improved by measuring tissues weight instead of sucrose concentration. The improved method was established by testing different plant tissues, which is simple, convenient and less error.

  The experiment was conducted in solar greenhouse with tomato varieties Zhongza No.9 and Beril, in order to investigate the nutrient absorption characteristics in winter-spring. The results showed that, except P 2O 5, the uptake rate and amount of total N, K 2O, Ca, Mg, and Fe of Beril is obviously higher than that of Zhongza No.9. The uptake percentage of main elements is also different between varieties. Zhongza No.9 has a higher percentage of P 2O 5 and K 2O, but has a lower percentage of Ca and Mg.
